Hello students in this question we have given acetic acid as a vic acid and sodium acid as a conjugate base.
00:07
The p .k value of cs3 cooh is 4 .74.
00:11
We need to calculate ph of gopper solution and that can be calculated using henderson -hoss -illbach equation.
00:35
Now we can write here the equation.
00:41
Here we can write equation.
00:45
We need to substitute value in this formula.
00:47
So here ph of buffer is 4 .3.
00:51
So we can write here 4 .3 which is equal to 4 .74 plus log of ch3, c -o -o -n -a, divided by c -h3.
01:12
C .o .h.
01:18
Now after calculating we are getting minus 0 .44 is equal to log ch3 c .o .o.
01:32
N .a.
01:33
Divided by ch3 c .c .o .h.
01:41
Now after simplifying log, we are getting 0 .363 which is equals to ch3 c .c .o .h.
01:51
C .o .o .n .a.
01:54
Divided by ch3 cooh.
02:03
After simplifying, we are getting 0 .363 into ch3 cooh, which is equals to ch3 coona.
02:20
Now concentration of buffer is equal to 0 .05 molar...
