Consider the following reaction at equilibrium. CH,COOH(aq) = CHyco0 (aq) + H*(aq) When NaCH3CO0 is added to the solution will the value of the equilibrium constant, K, and the pH of the solution increase, decrease, or remain the same? Select one: O A. K, decreases and pH increases O B. Ka remains the same and pH decreases O C. Ka decreases and pH remains the same O D. K, remains the same and pH increases O E. K, increases and pH decreases

h To add an 0 atom in basic solution, add 2 OH" to the side that needs the O atom, and also add an H20 to the other side. (OH has one more O than HOH). How many H20 molecules should be added to the left side? How many OH ions should be added to the right? H20 + CIO3 - CI" + OH Number of H50 molecules = 1 Number of OH ions =2
