Ph of khco3

WebbpH is defined as the negative of the base-ten logarithm of the molar concentration of hydrogen ions present in the solution. The unit for the concentration of hydrogen ions is moles per liter. To determine pH, you can use this pH to H⁺ formula: pH = -log([H⁺]) Step by Step Solution to find pH of 0.12 M : Given that, H+ = 0.12 M
