Weak Acid/Base vs. Strong
What is the best way to differentiate between a strong acid/base and a weak acid/base. For example how do we know ammonia is a weak base while sodium hydroxide is a strong base and acetic acid is a weak acid while HCl is a strong acid.

Re: Weak Acid/Base vs. Strong
The strength of an acid or base is defined by the extent of dissociation it has in water. So if it is completely dissociated, then it can be considered a strong base/acid. However, if it is partially dissociated, then it will be a weak acid/base.

Re: Weak Acid/Base vs. Strong
If it does completely dissociate in water how do you actually tell when this happens? Is there a way to tell how much it will dissociate?

Re: Weak Acid/Base vs. Strong
For the purposes of this class, I wouldn't worry too much about figuring out which bases/ acid is stronger because the best way of "figuring it out" would be experimentally. You may be able to have an idea of how much an acid/ base would dissociate based on electronegativity differences though.

Re: Weak Acid/Base vs. Strong
For this class, a good way to differentiate between strong acids/bases from weak acids/bases is by memorizing the strong ones. Only a few acids and bases are strong. If you do not recognize the acid as a strong acid, it is most likely a weak acid.

Re: Weak Acid/Base vs. Strong
It's honestly easier to memorize the strong acids and bases so when you have to identify the acids and bases, it will be quicker to recognize which are strong or weak.

Re: Weak Acid/Base vs. Strong
Can strength be measured by dissociation in a solvent other than water?

Re: Weak Acid/Base vs. Strong
Just like others have said, it is much easier to memorize the strong acids and bases to differentiate
