First we calculate the number of moles of sugar (which I assume is sucrose). number of moles = mass / molecular weight number of moles of sugar = 19 / 342 = 0.055 moles Now we may calculate the molarity of the solution. molarity = number of moles / solution volume (L) molarity = 0.055 / 0.05 = 1.1 M

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
