We are given a reaction: H2O2 + 2I- + 2H+ → 2H2O + I2 and are asked to find the initial number of moles of each reactant.
V=10mL and C=0.2 mol/L for potassium iodide in the solution.
V=5mL and C=0.5 mol/L for sulfuric acid in the solution.
V=5mL and C=0.02 mol/L for hydrogen peroxide in the solution.
n=CxV where n is the number of moles, C is the concentration, and V is the volume.
The Attempt at a Solution
I know we need to use the equation stated above but should we multiply by the coefficient or not?
