Use the definition of pH to compute the equilibrium hydronium concentration of this solution.
Create an ICE Table based on the given values, where I ''stands for the initial concentrations, C' stands for the changes in concentration, and'' E' stands for the equilibrium concentrations. Use multiples of z based on the stoichiometric coefficients in the balanced equilibrium equation to represent the changes in concentration in terms of x. Reactants decrease, so their changes are given negative values. Products increase, so their changes are given positive values. Keep in mind that the concentrations of liquids are never included in an ICE table. Note that the initial concentration of hydronium is
