Hi there.
00:03
In this question, we are asked to classify acetic acid, or its common name is vinegar, as a strong or weak acid.
00:12
When we're talking about acids or bases, strong versus weak refers to percent of ionization.
00:31
Strong acids, for example, hydrochloric acid, ionized in water, nearly 100%.
00:46
So pretty much all of it changes to h plus and cl minus.
01:03
That would be a strong acid when we get pretty much the same concentration of h plus as the original acid.
01:11
Weak acids only ionize a very small amount.
01:31
Generally speaking, acetic acid, ionizes about 1%.
01:45
Yes, that's only 1 % as opposed to a strong acid, which ionizes 100%, acetic acid only ionizes about 1%.
01:55
Therefore, it is definitely classified as a weak acid.
02:08
And since it only ionizes about 1%, we have a 0 .1 molar solution of the acetic acid here...
