Solid potassium hydroxide is slowly added to 75.0mL of a 0.176 M Melanesian acetate solution until the concentration of hydroxide ion is 0.0410 M. The percent of magnesium ion remaining in the solution is?

did you find the answer?

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
