what is the difference between an electrolyte and a nonelectrolyte This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you Identifying Strong Electrolytes, Weak Electrolytes, and Nonelectrolytes – Chemistry Examples. Following along are instructions in the video below:
This video. Were going to talk about how to identify a weak electrolyte. A a strong electrolyte and a non electrolyte.
So first whats the difference between these types of electrolytes. What you need to know is that a strong electrolyte conducts electricity. Very well a weak electrolyte conducts.
It just a little and a non electrolyte does not conduct electricity in water. So. What are some examples of strong electrolytes strong acid strong bases and ionic compounds that are very soluble our strong electrolytes.
These compounds they ionize completely in water. A weak electrolyte could be an insoluble compound. An insoluble ionic compound.
It could be a weak acid. A weak base. A non electrolyte could dissolve in water.
But it just doesnt on eyes weak electrolytes. They ionize may be 1 2. Strong electrolytes.
The ina is completely almost 100 percent ionization. So im going to give you some compounds and i want you to determine if its a weak strong or non electrolyte. So lets start with hcl hydrochloric acid.
Which category should we place this molecule in hydrochloric acid is a strong acid. So therefore. Its a strong electrolyte.
It on eyes is completely and it conducts electricity very well when placed in water now what about h f h. F. Is a weak acid it doesnt im a very well so hf is a weak electrolyte now what about h2so4 sulphuric acid.
So furyk acid is one of the strong acids that you need to know so. This would go in the strong electrolyte column now what about sucrose c12 h22 o11 sucrose table sugar dissolves in water. But it doesnt ionize sugar water is not conductive.
If you try to pass an electrical current to it nothing will happen it doesnt conduct electricity. So this is a non electrolyte since it doesnt ionize at all now what about sodium chloride. Table.
Salt salt dissolves in water. And it ionizes in water because it dissolves well because its soluble. Its going to be a strong electrolyte it ionizes completely now what about silver chloride.
According to the solubility rules silver chloride is insoluble. Its an ionic compound. But for the most part not in that percent of it does not dissolve.
Only a small fraction is also we can put this as a weak electrolyte. Theyre very very weak electrolyte. But only a small percentage actually break sevens ions.
Now what about ammonium chloride. Which category would you place this compound. In is this a weak electrolyte.
Strong electrolyte or a non electrolyte ammonium chloride breaks up into ammonium cations and chloride ions and according to the solubility chart. Ammonium is always soluble. So therefore.
This is a strong electrolyte anytime. You have a soluble ionic compound. It will ionize completely now what about potassium hydroxide.
Which category would you place this under koh is a strong base and anytime you have an alkaline earth metal. They not outsiders battle. But an alkali metal a group one metal.
They are always soluble. Which means they are not completely. And so they can be part of the strong electric category.
Another example of a strong base would be very american sign. Its soluble and it releases a lot of hydroxide ions in solution. It ionizes pretty well.
So thats it would be a strong electrolyte. Now what about lead two chloride. Where would you place that the halides are insoluble with silver lead and mercury.
So lets do chloride because its an insoluble ionic compound. Its going to be a weak electrolyte now what about methanol ch3oh typically when you have a hydrocarbon. If you have a molecule with carbon hydrogen and maybe some option as well for the most part not always.
But for the most part its going to be a non electrolyte alcohols like methanol and even fml c2h5oh sometimes you might see written this way ch3 ch2 o h. Ethanol and methanol these alcohols are non electrolytes they do not on eyes now theyre polar and so they dissolve in water you can mix them with water. But they dont ionize.
They dont form positive and negative charges and therefore they dont connect electricity. Which makes them non electrolytes. Now what about this one.
This is acidic acid is that a weak electrolyte strong electrolyte or non electrolyte. This is one of those molecules where it looks like a hydrocarbon with oxygen. But its not a non electrolyte.
Acetic acid is a weak acid. So it does ionize just a little only this hydrogen is acidic. The one on the left.
The other hydrogens are not acidic so it partially ionizes so for every hundred molecules of acidic acid maybe run out of those hundreds. My ionize into are these two ions. So therefore.
A static acid. Which can be found in vinegar is considered to be a weak electrolyte now what about ammonia nh3 does that ionize ammonia is a weak base. When you put it with water it grabs the hydrogen from water form in ammonium and hydroxide.
So therefore nh3. Its a weak electrolyte. It does cause ionization in water to occur.
So creates ions. So nh3 is a weak base. Which makes it a weak electrolyte in water.
Now what about potassium nitrate potassium nitrate is always soluble nitrates. Always soluble potassium. Which is an alkaline metal found in group one thats always soluble.
So thats going to be a strong electrolyte and finally glucose c6h12o6 glucose is a sugar molecule like sucrose so therefore. This is going to be a non electrolyte. It does not ionize so hopefully.
This gave you a good idea of how to distinguish a weak strong and non electrolyte. So keep this in mind strong electrolytes ionizes. Very well they have 100 percent ionization or close to it so strong electrolytes include strong acids strong bases and soluble ionic compounds a weak electrolyte conducts electricity partially so you have partial ionization it could be five percent or less so weak electrolytes include weak acids.
Weak bases and also in soluble ionic compounds. The last category are non electrolytes in a typical general chemistry course the most common molecules. Youll see in this area are the sugar molecules like glucose and sucrose and the alcohols like methanol ethanol propanol and things like that so thats it for this video.

Precalculus or confidence. I got videos on those topics as well so feel free to check that out when you chance. .
