Question

The sample contained an unknown metal, chlorine and water with the MeCl3·xH2O formula. the solution of this sample was electrolyzed for 22min using a current of 1.5A and 0.383g of metal was released at the metal was reacted with a constant voltage of electrolyte to react. However, 4.0575g of the sample was removed and gently heated to a constant weight of 300cels, leaving a dry residue of 2.4375g.
Task:
1. What metal was it?
2. Write and equate the electrolysis reaction equation.
3. How many milliliters of gas are released under normal conditions at the anode as a
result of electrolysis?
4. Determine the number of moles of crystalline water?
