Acids, bases, and salts are fundamental chemical compounds that we encounter daily in our lives. From the citric acid in lemons to the sodium hydroxide in soap, these substances play crucial roles in both natural processes and industrial applications. This chapter explores the definitions, propertie
Key Concepts
An acid is a substance
An acid is a substance that, when dissolved in water, furnishes hydronium ions (H₃O⁺) as the only positive ions. Acids have a sour taste, turn blue li
Acids are classified based on
Acids are classified based on: (1) Source: Mineral acids (HCl, H₂SO₄) vs Organic acids (CH₃COOH, HCOOH); (2) Strength: Strong acids (complete ionizati
A base is a substance
A base is a substance that reacts with hydronium ions from acids to form salt and water only. An alkali is a water-soluble base that furnishes hydroxy
pH is defined as the negative
pH is defined as the negative logarithm of hydronium ion concentration: pH = -log[H₃O⁺]. The pH scale ranges from 0-14, where pH 7 is neutral, pH < 7
Normal salts
Normal salts: Complete replacement of H⁺ ions (NaCl, Na₂SO₄); Acid salts: Partial replacement of H⁺ ions (NaHSO₄, KHCO₃); Basic salts: Partial replace
