Which of the following is a characteristic of a strong acid? O A. It does not conduct electricity in water.
B. It completely dissociates in water.
C. It reacts with water to form H2 gas.
O D. It increases the OH concentration.

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
