- Ka for acetic acid at 25.0C is 1754 105. At 55.0C, Ka is 1.625 105. What are H and S for the ionization of acetic acid?arrow_forwardMost naturally occurring acids are weak acids. Lactic acid is one example. CH3CH(OH)CO2H(s)+H2O(l)H3O+(aq)+CH3CH(OH)CO2(aq) If you place some lactic acid in water, it will ionize to a small extent, and an equilibrium will be established. Suggest some experiments to prow that this is a weak acid and that the establishment of equilibrium is a reversible process.arrow_forwardCl2(g) + H2O(l)-> Cl–(aq) + ClO-(aq) + 2H+(aq) The addition of which substance would move the above equilibrium to the right and why?
