WebJan 5, 2016 · Now, phenolphthalein, itself a weak acid, is an indicator that is colorless at pH values that are below #8# and pink, even fuschia, at pH value that are above #10# and below #12#. The half-way stage, where you have equal amounts of phenolphthalein and ionized phenolphthalein, takes place at a pH of about #9.6# . WebJan 30, 2024 · Howto: Solving for Ka. When given the pH value of a solution, solving for Ka requires the following steps: Set up an ICE table for the chemical reaction. Solve for the concentration of H 3O + using the equation for pH: [H3O +] = 10 − pH. Use the concentration of H 3O + to solve for the concentrations of the other products and reactants. grammy 2020 nominations
