82. Formulate the rule of the ionic product of water. Will the value of the ionic product of water change with increasing temperature, diluting the solution and adding acid and alkali to it? What is pH? Calculate the values ​​of pH, pOH based on the concentrations in the table or the values ​​of the concentrations of the substance based on the values ​​of pH, pOH in the table. Make calculations for all columns of the table related to your option. The activity coefficient in solutions of strong electrolytes is equal to 1. The values ​​of the dissociation constants are given in the appendices.
