IB Chemistry HL 2.1.3 Limiting reactant
Learn to identify the limiting reactant from amounts or observations, then use it to calculate the maximum amount of product formed.
How this is tested
- identify the limiting reactant by comparing mole ratios, e.g. 0.20 mol Mg with 0.20 mol HCl
- deduce HCl is limiting when the same NaHCO3 mass gives different CO2 masses in acids of different c
- calculate theoretical yield once the limiting reactant is known, including product masses from equations
