Question

Σ
A solution containing 0.319 g of CrCl3.6H2O was passed through a
cation exchange resin and acid coming out of the cation exchange resin
required 28.5 mL of 0.125 M NaOH. Determine correct formula of the
complex [mol, Wt of the complex = 266.5)​

Answer 1

Answer:

A solution containing 0.319 g of complex CrCl3. 6H2O was passed through cation exchanger and the solution given out was neutralised by 28.5 ml of 0.125 m NaOH. The correct formula of the complex will be: [ molecular weight of complex =266.5
