What volume of O_{2} (g) at 0^{o}C and 760 mmHg is produced
when 5 A of current is passed through a dilute aqueous solution of KCl for
5 minutes?
Don't be fooled, this problem was simply an electrolysis of water question
in disguise.
Problem :
Molecular masses can be determined through electroplating. Determine the
molecular mass
and identity of a +2 metal, X, that plates 46.3g of X in 6.75 hours at a
current of 2 A.
Problem :
How long will it take for 1.25 L of a 1.0 M CuSO_{4} solution being
electrolyzed with a current of 3.40 A to reach a concentration of 0.25 M?
