it is heated from 30 °C to 50 °C? *
A).4 J/g °C
B).2 J/g °C
C).1 J/gºC
D).5 J/g °C

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
