When 0.50 M CS2 and 1.50 M Cl2 are placed in a container and allowed to come to equilibrium, the mixture is found to contain 0.125 M CCl4. What is the concentration of Cl2 at equilibrium

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 answers are

c and c
