A hydrated nickel chloride compound was found to contain 24.69% Ni, 29.83% Cl, and 45.48% water. Determine the empirical formula of this hydrated compound

Expert Solution

element % A.wt relative number simple ratio

Ni 24.69 59 24.69/59 = 0.418 0.418/0.418 = 1

Cl 29.83 35.5 29.83/35.5 = 0.84 0.84/0.418 = 2

H2O 45.48 18 45.48/18 = 2.53 2.53/0.418 = 6

empirical formula = NiCl2. 6H2O
