a 0.241 -g sample of NaCl (molar mass=58.44g/mol) is dissolved in enough water to make 5.20 mL of solution. Calculate the molarity of the resulting solution

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
