Interpretation: Theoretical and Percent yield of hydrogen in the electrolysis of water is to be determined
Concept Introduction: Electrolysis of water is the process in which electricity is used to split water in hydrogen and oxygen gas.
Answer to Problem 102A
The theoretical yield of H2 is 4 g.
Percent yield of H2 is 95%.
Explanation of Solution
Step 1: Write balance chemical equation
Step 2: Convert the mass of reactant to moles
Step 3: Convert moles of reactant to moles of product using a mole ratio.
2 mole of
Step 4: Convert moles of product to mass (theoretical yield)
Actual yield = 3.8 g (given)
