In this question, we have to take 0 .5 molar of each of the following compounds in a solution.
00:09
And we have to arrange the ph order of the solution.
00:15
So first is n .a .o .h.
00:19
This is sodium hydroxide.
00:21
This is pure base.
00:27
Second is hbr, which is pure acid.
00:34
Next is nac -ch -3 c -d -o.
00:41
When we treat this with water, we get n -a -o -h plus c -h3 -d -bond -o -o -h.
00:55
N -a -o -h is a strong base and ch3c -c -w is a weak acid.
01:05
So the mixture of strong base and weak acid produces a mild base.
01:16
Now we come to kbr, kbr.
01:21
When we treat this with water, we get k -o -h plus hbr.
01:28
K -o -h is a strong base and hbr is a strong acid.
01:34
So the resultant solution will be neutral.
01:37
Or we can say that the ph will be equal to 7...
