Questions & Step-by-Step Solutions

What is the pH of a 0.1 M solution of sulfuric acid (H2SO4)?
  • Step 1: Understand that sulfuric acid (H2SO4) is a strong acid, which means it completely breaks apart in water.
  • Step 2: When H2SO4 dissolves in water, it releases hydrogen ions (H+). For a 0.1 M solution, this means it produces 0.1 M of H+ ions.
  • Step 3: The pH scale measures how acidic or basic a solution is. The formula to find pH is pH = -log[H+].
  • Step 4: Substitute the concentration of H+ ions into the pH formula: pH = -log(0.1).
  • Step 5: Calculate -log(0.1). The result is 1, so the pH of the solution is 1.
