Hello students in this problem we will calculate the ph of 0 .71m k -o -h solution.
00:07
The ph of 0 .71 molar k -o -h solution.
00:18
To calculate the ph, we know the ph is having the formula of negative logarithm of h plus ion concentration, but it has given that it is having the oh minus ion concentration.
00:31
So we know the formula that is to calculate the oh minus ion concentration it has given, that is 0 .71m.
00:41
To calculate the h plus ion concentration, we know the value that is the dissociation constant of water divided by the oh minus ions concentration.
00:51
It is the concentration of oh minus ion.
00:55
It is having the value.
00:56
The kw is the disassociation constant of water having the value 1 into 10 to 0 minus 14m.

Divided by 0 .71 molar...
