This creates a contamination risk. The Ka of HC2H3O2 is found by calculating the concentrations of the reactants and products when the solution ionizes and then dividing the concentrations of the products multiplied together over the concentration of the reactant. Neutralization reaction is one type chemical of reaction in which acid and base reacts with each other in a quantitative amount to form salt and water. between: a.
