Answer to Question #120292 in General Chemistry for ogooluwa

Question

what mass of hydrogen gas is produced when 1.25A of current is passed through and electrolytic cell

Answer 1

Solution.

$I=1.25A;$

Electrochemical equivalent of hydrogen:

$k=0.0104\sdot10^{-6}kg/Cl;$

$m=kIt;$ $t-$ the time during which the current passed;

$m=0.0104\sdot10^{-6}kg/Cl\sdot1.25A\sdot ts=1.3\sdot10^{-8}t(kg);$

Answer: $m=1.3\sdot10^{-8}t(kg).$
