If the pH of a solution is 3, what is the concentration of H+ ions? (2023)
Step 1: Understand that pH is a measure of how acidic or basic a solution is.
Step 2: Know that the formula to find the concentration of hydrogen ions (H+) from pH is: [H+] = 10^(-pH).
Step 3: Since the pH given is 3, substitute 3 into the formula: [H+] = 10^(-3).
Step 4: Calculate 10^(-3), which equals 0.001.
Step 5: Conclude that the concentration of H+ ions is 0.001 M.
pH and Hydrogen Ion Concentration – The pH scale measures the acidity or basicity of a solution, where pH is the negative logarithm of the hydrogen ion concentration ([H+]). A pH of 3 indicates a higher concentration of H+ ions.
