What is the formula for calculating the concentration of hydrogen ions in a solution from its pH?
  1. [H+] = 10^-pH
  2. [H+] = pH/10
  3. [H+] = 10^pH
  4. [H+] = pH^10

Questions & Step-by-Step Solutions

What is the formula for calculating the concentration of hydrogen ions in a solution from its pH?
  • Step 1: Understand that pH is a measure of how acidic or basic a solution is.
  • Step 2: Know that the pH scale ranges from 0 to 14, where lower values are more acidic.
  • Step 3: Remember that the formula to find the concentration of hydrogen ions ([H+]) is based on the pH value.
  • Step 4: The formula is [H+] = 10^-pH, which means you take 10 raised to the power of negative pH.
  • Step 5: If you have a pH value, plug it into the formula to calculate [H+]. For example, if pH = 3, then [H+] = 10^-3 = 0.001 M.
