Alrighty, so chapter 2, problem 15, gets a little mathy, which a lot of people have an aversion too.
00:07
But let's talk about the ph scale here.
00:10
So it runs from zero all the way up to 14.
00:15
And at zero, we're most acidic.
00:20
And at 14, we are the most basic.
00:25
And of course, neutral.
00:27
Right in the middle, that's 7.
00:28
Now each of these numbers represents 10 times difference.
00:41
Okay, so if you want to go from, say, 6 to 7, you would be becoming 10 times more basic than you were at 6.
01:03
Alternatively, if you were to go from, let's pick some other numbers up here, if you want to say, if you want to go from, if you want to go from, if you want to go from 10 to, to 9, then you'd be becoming 10 times more acidic because you're moving in the direction of acidity...
