A 250.0 ml solution of 0.100 m hclo is titrated with 0.200 m naoh. What is the expected ph of the resulting solution once 50.0 ml of the naoh solution has been added to the hclo solution?

i think it is true since you can test the answer and can use observations to complete it.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

the answer your looking for is c).
