Show how you would work carry out this calculation: 1.96g of an unknown hydroxide X(OH)2 was dissolved in water, and the solution was made up to 250.00cm in a volumetric flask. In a titration, 25.00cm of this solution of
X(OH)2 required 21.20cm of 0.250 mol dm' HCl(aq) to reach the end point.
Equation: 2HCl(aq) + X(OH)2(aq) → XC12(aq) + 2H2O(1)
