Ions in Acid Solutions
Part of the Acids and Bases section of Coddy's Chemistry journey. Lesson 9 of 30.
A strong acid or base splits completely. Read the ions off the formula:
H₂SO₄ + 2H₂O → 2H₃O⁺ + SO₄²⁻
In 0.2 M H₂SO₄: [H₃O⁺] = 0.4 M and [SO₄²⁻] = 0.2 M.
Strong bases too: Ba(OH)₂ → Ba²⁺ + 2OH⁻, so 0.05 M Ba(OH)₂ has [OH⁻] = 0.1 M.
0.2 M H₂SO₄
Challenge
A car battery acid sample is sulfuric acid. Taking both protons as fully given, what is [H₃O⁺]?
