Question

Balancing Redox Equations and Stoichiometry:

Part A

Balance the following equation:

K2CrO4+Na2SO3+HClKCl+Na2SO4+CrCl3+H2O

Generally coefficients of 1 are omitted from balanced chemical equations. When entering your answer, include coefficients of 1 as required for grading purposes.

Enter the coefficients for each compound, separated by commas, in the order in which they appear in the equation (e.g.,  1,2,3,4,5,6,7).

Part B

In the process of oxidizing I to I2, SO42 is reduced to SO2. How many moles of SO2 are produced in the formation of one mole of I2?

Express your answer numerically in moles.

Explanation / Answer

Part A :

2K2CrO4 + 3Na2SO3 + 10HCl -----> 4KCl + 3Na2SO4 + 2CrCl3 + 5H2O

coefficients (2 , 3 , 10 , 4 , 3 , 2 , 5)

ParT B :

2 I- + SO4 2- + 4 H+ ------------------> I2 + SO2 + 2 H2O

1 mole of SO2 required.

formation of one mole of I2 , 1 mole of SO2 required.
