Reaction calculations
WebTranscript When a weak acid and a weak base are mixed, they come to an equilibrium state represented by the following equation: HA (aq) + B (aq) ⇌ A⁻ (aq) + HB⁺ (aq). WebThese quantitative relationships are known as the reaction’s stoichiometry, a term derived from the Greek words stoicheion (meaning “element”) and metron (meaning “measure”). In this module, the use of balanced chemical equations for various stoichiometric applications is explored. The general approach to using stoichiometric ...
