Identifying Strong Electrolytes, Weak Electrolytes, and Nonelectrolytes - Chemistry Examples
 
10:13
This chemistry video tutorial explains how to identify weak electrolytes, strong electrolytes, and nonelectrolytes. Strong electrolytes including strong acids and bases as well as soluble ionic compounds that ionize completely in solution. Weak electrolytes include weak acids and bases and insoluble ionic compounds that ionizes partially in aqueous solution. Nonelectrolytes may be soluble in water but they do not ionize. Sugar and alcohol mixed with water are common nonelectrolytes that do not conduct electricity.

How to Identify Strong, Weak, and Non-Electrolytes
 
05:44
If you liked my teaching style and are interested in tutoring, go to http://www.conquerchemistry.com/online-tutoring/ In this video, you'll learn what strong electrolytes, weak electrolytes, and nonelectrolytes are. Then you'll learn how to identify whether a compound is a strong, weak, or non-electrolyte. An electrolyte is a compound that dissolves in water to produce a solution that conducts electricity. A strong electrolyte is a compound that readily dissociates. Strong electrolytes are either strong acids, strong bases, or soluble ionic compounds. A weak electrolyte is a compound that partially dissociates. Weak electrolytes are either weak acids, weak bases, or insoluble ionic compounds. Weak electrolytes conduct electrical current poorly. A non-electrolyte is a compound that does not dissociate when dissolved in water. Non-electrolytes are covalent compounds that aren't acids nor bases. By the end of this video, you'll know exactly how to Identify Strong, Weak, and Non-Electrolytes.

How Are Strong and Weak Acids Different | Chemistry for All | FuseSchool
 
05:26
Learn the basics about strong and weak acids, and how they differ. Strong acids are often used in School Science labs for experimentation but they have important uses in industry and the everyday world. Sulphuric acid for example is found in car batteries but industry uses 200 million tonnes annually for the chemical industry. Hydrochloric acid found in your stomach and nitric acid are also examples of strong acids. Acids react with water to produce hydrogen ions, or more strictly hydroxonium ions: Strong acids dissociate fully into their ions. Most acids are weak, and remain largely as molecules in solution. Acids can be identified by using full-range indicator from 0 to 7 on the pH scale. pH is a measure of the concentration of hydrogen ions. If you dissolve 1 mole of a strong acid, like HCl in water to make 1litre of solution it dissociates completely into ions so you also get 1 mole per litre of H+ ions, and a pH of 0. To get a solution of pH 4 you have to dilute this with 10,000 times its volume of water. We still have a STRONG acid but it is VERY dilute! However, if you dissolve 1 mole of a weak acid, like ethanoic acid (also called acetic acid) to make a litre of solution it remains mostly as undissociated molecules. If an acid is only 0.01% dissociated - so only one molecule in 10,000 are split into ions. Although the concentration of acid is 1 Mole, the concentration of hydrogen ions is only 0.0001 moles per litre, that is 10 to the power negative 4, making the pH 4. So here is an example of a fairly concentrated acid which is weak. So acids cab be both concentrated and fully dissociated so STRONG, concentrated but not fully dissociated so WEAK, dilute but STRONG because fully dissociated or finally dilute and weak. A weak acid can be concentrated and a strong acid can be dilute. Most acids are commonly occurring organic acids such as you find in lemons or vinegar - which are all WEAK so remain mostly as molecules and often have a smell. There are only a few STRONG acids, mostly non-metal oxides dissolved in water like sulfuric and nitric acids, but there is also Hydrochloric acid - found in your stomach to aid digestion!

Strong and Weak Acids - Examples and Explanation
 
02:48
The primary difference between strong and weak acids is how the behave in water. Strong acids dissociate (break apart) completely in water). For example, HCl, a strong acid will break apart into H+ and Cl- ions. Weak acids dissociate partially in water. For example, HF, a weak acid, will only have some of the HF molecules dissociated at any given time. It is also to be able to distinguish between concentrated and dilute acids. This is covered at the end of the video.

Strong and Weak Alkalis | Chemistry for All | FuseSchool
 
02:53
An acid is a substance that will dissociate in water to give a proton (or H+ ion) and a conjugate base. An acid is considered to be strong if dissociation nears 100%, and weak if dissociation is usually less than 1%. In this lesson, we will learn about strong alkalis and weak alkalis. An alkali is a soluble base that has a pH greater than 7, turns red litmus paper blue, and universal indicator solution green if it is weak and blue to purple if it is strong. But in the absence of universal indicator solution, how can we tell if an alkali is strong or weak? In water, sodium hydroxide dissociates into a Na+ ion and a OH- ion. Since sodium hydroxide almost completely dissociates (100%), it is considered to be a strong alkali. The concentration of OH- ions in a solution containing a strong alkali will be high. Other examples of strong alkalis include potassium hydroxide and calcium hydroxide. These substances, when dissolved in water will turn universal indicator solution a very deep purple, and are highly corrosive. In contrast, a weak alkali is one that does not completely dissociate in water. A good example of a weak alkali is ammonium hydroxide (NH4OH). In water, it does not completely dissociate into its respective ions. The concentration of OH- ions in a solution containing a weak alkali will be much lower. These substances, when dissolved in water will turn universal indicator solution a green or light blue, and are less corrosive than strong alkalis for a given concentration. In conclusion, a strong alkali dissociates almost completely in water to give a high concentration of hydroxide ions, whereas dissociation for a weak alkali is much less and therefore the concentration of hydroxide ions is much lower.

View full lesson: http://ed.ted.com/lessons/the-strengths-and-weaknesses-of-acids-and-bases-george-zaidan-and-charles-morton Vinegar may have a powerful smell, but did you know it's actually a weak acid? In the chemical economy, acids actively give away their protons while bases actively collect them -- but some more aggressively than others. George Zaidan and Charles Morton use the currency of subatomic particles to explain this unseen exchange. Lesson by George Zaidan and Charles Morton, animation by Karrot Animation

8.4 Strong and weak acids and bases (SL)
 
03:47
8.4 Strong and weak acids and bases Understandings: Strong and weak acids and bases differ in the extent of ionization. A strong acid is a good proton donor and has a weak conjugate base. A strong base is a good proton acceptor and has a weak conjugate acid. Guidance: The terms ionization and dissociation can be used interchangeably.

8.4 Distinguish between strong and weak acids and bases IB Chemistry [SL IB Chemistry]
 
02:30
8.3.1 Distinguish between strong and weak acids and bases in terms of the extent of dissociation, reaction with water and electrical conductivity. "Strong" in this context means that the acid (or base) is completely dissociated when added to water. This gives high electrical conductivity since there are lots of free moving charged particles. Strong acids (and bases) react faster than weak ones since the strong have much higher concentrations of ions. Strong acids/bases tend to be more dangerous than weak ones. "Weak" means partially dissociated -- a weak acid will only release very few protons into solution and a weak base only releases very few hydroxide ions. Dr Atkinson strongly hopes to be awakened from his Inception dream sometime this weak. Leave chemistry alone!

We’ll learn how to identify them based on their extent of dissociation – more specifically strong acids dissociate completely and weak acids partially – and see some examples. Then we’ll be introduced to the acid dissociation constant Ka, a measurement to present the strength of an acid in a solution, and its logarithmic version pKa which is more convenient to use. In conclusion, we’ll look at an exam style question.
