The Keq for the reaction of water with water is called KwH2O + H2O ⇔ H3O+1 + OH-1 [H3O+1][OH-1] Kw = ––––––––––––– = [H3O+1][OH-1] = (1 x 10-7)2 = 1 x 10-14 [H2O]2 The inverse logarithm, or -log, of [H3O*][OH1] = 10-14 is pH + pOH = 141. What happens to the [H30*1] when acid is added to neutral water ?the [H3O*'] goes2. What happens to the pH when acid is added to neutral water ?an example of an increased [H30*l] is [H30*l]=1 x 10-6. Thus pH = -log[10ʻ] = 6thus, adding acid makes the pH go3. What happens to the [OH'] when acid is added to neutral water ?in the equation [H3O+'][OH´1] = 10-14, when [H3O*1] increases, the [OH1] goes4. What happens to the pOH when acid is added to neutral water ?when [OH-'] decreases, the pOH goessince the pOH = -log[OH1]this can also be seen using pH + pOH = 145. What happens to the Kw when acid is added to neutral water ?because it's a constant.a. downb. upc. no change

Water has many unique properties that make it very special and important for life on earth. The presence of hydrogen bonds within the water molecules and the ability of water molecules to form a hydrogen bond with other molecules make it a universal solvent. Pure water is a neutral solution and has a pH of 7. Water is the major component of the cells and our body. The water exists in equilibrium with H+ and OH- ions. The product of the concentration of H+ and OH- ions is always 1×10-14 M. 1) When acid is added to the water, the acid release H+ ions, increasing the concentration of H3O+ ions in the solution. Therefore, the blank has to be filled with up. 2) pH of a solution, is the negative logarithm of H+ ion concentration present in the solution. Thus, they are inversely proportional, as the concentration of H+ ion increase, the pH decrease. Adding acid to a neutral solution, increase the H+ ion in the solution, decreasing the pH of the solution. Therefore, the blank has to be filled with down 3) When, the H3O+ ions concentration increases on the addition of acid, the concentration of OH- ions reduces to re-establish the equilibrium. As a result, the Kw of the water remains constant, 1×10-14 M. Therefore, the blank has to be filled with down. 4) The Kw is the product of the concentration of H+ and OH- ions the value of Kw is always the same (constant), and the value is 1×10-14 M. Therefore, the blank has to be filled with no change.
