Questions & Step-by-Step Solutions

What is the pH of a solution with [H+] = 0.00001 M?
  • Step 1: Identify the concentration of hydrogen ions [H+]. In this case, [H+] = 0.00001 M.
  • Step 2: Use the formula for pH, which is pH = -log[H+].
  • Step 3: Substitute the value of [H+] into the formula: pH = -log(0.00001).
  • Step 4: Calculate the logarithm: log(0.00001) = -5.
  • Step 5: Apply the negative sign: pH = -(-5) = 5.
