WebpH 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 0.055 M : Given that, H+ = 0.055 M WebOct 22, 2024 · Weak Acid pH Calculations We typically write the acid dissociation as: HA ⇌ H + + A − Noting that water is omitted and hydronium is written as H + (implicitly meaning H 3 O + and not a free proton). This gives the following equilibrium constant Ka = …
