Identifying Strong Electrolytes, Weak Electrolytes, and Nonelectrolytes - Chemistry Examples

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.

Strong Electrolytes include: strong acids, strong bases, very soluble compounds.
Weak Electrolytes include: An insoluble ionic compound, weak acid, weak base
You have to have all the acids and the solubility rules memorized if you guys are confused as to wtf is going on.

Things to search first before watching this:
1. How to know if they're weak / strong acid
2. How to know if they ionize in water

[cynthiasabazali]

This is so frustrating! How do we know what compounds are strong/weak acids/bases? Is that just memorization? If so, why doesn't any video just let us know?! I get that electrolytes and strength/weakness have a direct relationship, but how do you determine that?

[kinbela]

FYI this video is great for practice. I would look up and memorize what are you strong bases, acids, and soluble/insoluble salts first. Then use this as practice. If you come here without even trying, it could probably not be the best. But if you come to this video prepared, it feels like such a great boost!

I know this has been like 3 years ago, but if anyone is needing help with this, you are needed to be able to remember that non electrolytes are covalent compounds, or a non metal and non metal, such as glucose. However, some like NH3 does have covalent compounds and the nitrogen is extremely soluble in water, making it a weak base. Strong acids would have a H+ in front, with them constituting to the saying of CSI NBC, or Charlie Brown Is Now Super Charles, and weak acids would be the opposite of these 7. Stronger bases would start with a group 1/2 ion combined usually with a hydroxide.

After practising for months now i'm starting to get a good idea of what constitutes a strong electrolyte.. but a lot of it is memorization. This is important stuff to know about for questions involving the common ion effect/ LCP, etc

[Misscoolisthename]

your voice is so relaxing. chemistry is my favorite class but is often stressful. your videos before bed are so nice
thank you <3

[imberrysandy]

My teacher keeps referring back to your channel as supplemental material. I love how you making things easier to understand the main point

[PPando]

How can you tell if the ionize ?
Or tell if they are an electrolyte

[sethwiggins]

Okay- This is a late post, but a great breakdown.

Solubility is not equal to electrolytes.

Solubility is determined by the solubility charts.

Strong electrolytes are Ionic Compounds or Molecular Compounds that semi-ionize (7 Strong Acids/8 Strong Bases)

Weak Electrolytes tend to be anything that ionizes just a tad (Weak Acids/Weak Bases)

Non-electrolytes are usually molecular compounds.

Professor Organic Chemistry Tutor, thank you for a short and sweet explanation of How to Identify Weak Electrolytes, Strong Electrolytes and Nonelectrolytes in AP/General Chemistry. The strong/weak acids and bases increases my understanding of this material. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

A common misconception is that insoluble ionic compounds are weak electrolytes. In fact all ionic compounds are strong electrolytes, because that which is dissolved exist entirely as ions in water. Even insoluble ionic compounds (e.g., AgCl, PbSO4, CaCO3) are strong electrolytes, because the small amounts that do dissolve in water do so principally as ions; i.e., there is virtually no undissociated form of the compound in solution. That which is insoluble exists in the solid crystal phase and is therefore by definition not in solution and even "insoluble" ionic compounds have some degree of solubility however small. The extent to which an electrolyte dissolves in solution does not indicate whether it is strong or weak. It is the relative proportion of dissociated and associated species in solution. For any ionic compound, all of the species in solution are dissociated.

thank u so much. i had dowloaded tons of ur video pls keep it up. you are great teacher! i'm migrating from non science to science pls always make it easier ans simple for someone like me. thanks alot u have been a great help.

[aaronius]

Hey man. Usually your videos are great, but this one didn;t explain how to know if each compound is ionic or molecular which determines their ability to conduct electricity lol.

[earth]

Well, I noticed most of strong electrolytes are either strong acid or strong basic as well as salt from strong acid and strong basic. But, NH4Cl which is salt from weak basic and strong acid is strong electrolyte? How do you determine if the solution is strong or weak? Is NH4Cl the exception?

[jesseloving]

But why though, I already have lists of strong/weak acids/bases. How do you determine which is more or less soluble. My solubility chart looks just like everyone else's just soluble/insoluble?

[itsworldwideguy]

Sigma rule : any compounds which contains no3, so4, cl they are strong electrolyte rest of them are weak electrolyte💫 you can easily solve any type of question 😉 #neetaspirants

[amsayals]

first time watched ur video.
Teaching very well. but ur teaching vry fast.

[elizabethpadilla]

can u explain WHY its a strong weak or nonelectrolyte? ...not just say the answer -.-

[aaronius]

So if you had like MgBr2 would that be strong electrolyte or a weak one?
