In this video, we're going to talk about acid -based buffers.
00:04
Acid -based buffers resist change in ph.
00:10
This is really important in a lot of chemistry applications, but one that's pertinent to everyday life is blood.
00:20
The ph of blood is approximately 7 .4.
00:24
And if this ph changes too much, so if it goes too high or too low, it can be very dangerous.
00:29
So the buffer system within your blood makes it so that the ph of the blood doesn't change too drastically, so it stays in that safe range.
00:40
A buffer system consists of a weak acid and its conjugate base, or a weak base and its conjugate acid.
01:08
A weak acid or base and its conjugate base or acid together is called a conjugate pair.
01:23
So in order to see how an acid -based buffer works, let's look in an example...
