How many moles of hydrochloric acid must be added to a liter of buffer that is 1 .5 molar in acetic acid and 0 .75 molar in sodium acetate if we desire a buffer of 4 .10? okay, so let's go ahead and write down our chemical formula here because there's my acetic acid.
00:30
This is my l.
00:35
This is an aq.
00:36
Q.
00:37
That'll be in equilibrium with my acetate ion and my h2o.
00:56
Hello? hey, are you upstairs? no.
01:05
Okay, let me finish this problem.
01:07
Okay, 435.
01:09
Okay, sorry about that.
01:15
I got a call.
01:16
So let's go ahead ahead and figure this out.
01:20
So i'm going to, after i'm going to figure out my ice table here.
01:31
So i have 1 .5 in this and i'm going to be adding ch plus.
02:01
So after adding my h3o plus, got it.
02:13
So this this is 0 .75.
02:18
This is 1 .5.
02:21
And after i add my h plus, what's going to happen here? i'm going to add h plus.
02:43
I'm going to add x amount of this.
02:48
So this is going to go down x.
02:51
Whoopsie.
02:52
This one's going to go up x.
02:55
And this is going to go down by x.
02:57
Okay...
