How can the knowledge of stoichiometry help us to resolve reactions between ions in solutions?

At its most basic level, stoichiometry represents the conservation of mass: given 10 g of reactant, a maximum of 10 g of product can be produced. However, charge is also conserved in chemical reactions; to represent a redox reaction, electron addition or removal is used to represent reduction or oxidation, respectively. The charge conservation is demonstrated by cross-multiplying the individual redox reactions.

Knowledge of stoichiometry helps us resolve reactions between ions in solutions by allowing us to determine the precise quantities of reactants and products involved in a chemical reaction. This enables us to predict the amounts of substances that will be consumed or produced, as well as the ratios in which they will react or combine. By applying stoichiometric principles, we can balance chemical equations, calculate molar quantities, and determine the limiting reactant, which are essential steps in understanding and predicting reactions between ions in solutions.
