When a solution of chromium salt X is electrolysed, chromium metal is deposited on the cathode, according to the following equation.
Crn+(aq) + ne- → Cr(s)
When a current of 1.8A was passed for 40 minutes through a solution of salt X, it was found that 0.776 g of chromium had been deposited.
Calculate the value of n in the above equation. Show your working.
The enthalpy of formation of MX2 is ?Hf° = -829 kJ/mol. The enthalpy of sublimation of M is ?Hsub = 117 kJ/mol. The first and second ionization energies of M are IE1 = 717 kJ/mol and IE2 = 1433 kJ/mol.
