b)n=4 to n=2
c) n=3 to n=2
d) n=3 to n=1
e) n=2 to n=1

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

explanation:

scientist are people who discover why and how things are done and made in the world.
