Questions & Step-by-Step Solutions

What is the pH of a solution with a hydrogen ion concentration of 1 x 10^-3 M? (2019)
  • Step 1: Identify the hydrogen ion concentration given in the question, which is 1 x 10^-3 M.
  • Step 2: Use the formula for pH, which is pH = -log[H+].
  • Step 3: Substitute the hydrogen ion concentration into the formula: pH = -log(1 x 10^-3).
  • Step 4: Calculate the logarithm: log(1 x 10^-3) equals -3.
  • Step 5: Substitute this value back into the pH formula: pH = -(-3).
  • Step 6: Simplify the expression: pH = 3.
