Study Notes

Neutralization Reactions

  • Dilute acids react with alkalis to produce salt and water.
  • This process is referred to as a neutralization reaction.
  • Bases and alkalis are capable of neutralizing acids, resulting in the formation of salts alongside water.

Brønsted–Lowry Concept

  • Defines acid-base reactions as involving proton transfer.
  • Emphasizes that these reactions are universally reversible.
  • Conclude with an establishment of acid-base equilibrium as a result of the reaction dynamics.
