Hi there.
00:03
This question is about an indicator, and you use an indicator when you're doing acid -based titrations.
00:11
An indicator is a substance that is going to change different colors based upon whether the solution is acidic or basic.
00:27
So i'm going to say discernible colors.
00:30
So colors that we can tell are different.
00:46
All right.
00:46
So we use that indicator for, and that's what this question is asking.
00:51
We have five possible options there.
00:53
I'm just going to.
00:54
To label them a, b, c, d, and e, as i want to talk about each one.
01:02
So the first one, letter a, to bring the equivalence point to seven.
01:07
While that is false, an indicator does nothing with the actual equivalence point.
01:14
It just gives us a color change to let us know what's going on.
01:18
Letter b says, it's fun to add indicator...
