Hi there.
00:03
In this question, it is asking about a weak acid.
00:07
So to answer this question, i want to compare a strong acid versus a weak acid.
00:17
First of all, strong versus weak when we're talking about acids, is not referring to the concentration.
00:24
That would be concentrated or dilute.
00:26
Those are the terms we would use there.
00:29
But strong acid versus weak acid refers to the amount of dissociation.
00:35
Strong acids, completely.
00:37
Dissociate in water or nearly completely dissociate.
00:48
And what that means, dissociation means they are forming ions, one of which is the hydrogen ion.
01:03
Weak acids on the other hand only dissociate a very small amount.
01:21
For example, acetic acid, which is vinegar, only dissociates about 1%.
01:27
So a very small amount indeed.
01:31
So as we look at the answer options here, which is the following is a characteristic of weak acid.
01:36
Letter a says it's not as dangerous as a strong acid.
01:40
Well, that is not true because to talk about how dangerous it is, we also need to know its concentration...
