Now let's take up this question.
00:02
In the question, ksp value for the nickel to hydroxide, it is given as 5 .5 multiplied with 10 raised to the power minus 16.
00:18
This is the ksp solubility product.
00:21
So we have to find the ph of the saturated solution of the nickel hydroxide.
00:28
So the answer to the part 1 can be calculated as follows.
00:36
Nickel hydroxide, it can dissociate in aqueous medium like this to give nickel to positive along with 2 -0 -8 -negative ions.
00:47
So ksp can be written.
00:50
Concentration of nickel -2 -positive ion, concentration of o -h -negative ion along with the square.
00:58
So 5 .5 multiplied with 10 raised to the power minus 16 will become 5.
01:06
S, let us say concentration of nickel is s.
01:10
And along with that, concentration of o h would become 2s and square of 2s.
01:14
So it will become 5 .50 multiplied with 10 raised to the power minus 16, 4s square...
