Correct: Acids have a sour taste, Buffers maintain pH as equilibrium shifts when acid or base is added, When water self-ionizes, it produces H3O+ & OH-, A conjugate pair has formulae that differ by 1 H+, Acid-base neutralization reactions produce water & a salt, Bases have pH > 7, Acids have pH < 7, If product concentration increases, equilibrium shifts left, If reactant concentration increases, equilibrium shifts right, If product concentration decreases, equilibrium shifts right, If reactant concentration decreases, equilibrium shifts left, Buffering is an example of LeChatelier's principle, Equivalence is shown as the point of inflection on a titration curve, Endpoint for a titration is when the indicator changes color, Equivalence point for a titration is when the acid's H+ balances the base's OH-, Buffers are made with a weak acid or base & a conjugate salt, pH of a salt depends on relative strengths of its parent acid & parent base, Incorrect: Bases have a sour taste, A conjugate pair has formulae that differ by 1 OH-, Bases have pH < 7, Acids have pH > 7, If product concentration increases, equilibrium shifts right, If reactant concentration increases, equilibrium shifts left, If product concentration decreases, equilibrium shifts left, If reactant concentration decreases, equilibrium shifts right, In every titration, end point = equivalence point, Equivalence for all titrations is at pH = 7, Equivalence for a titration is when the indicator changes color, Buffers are made with a strong acid or base & a conjugate s, Salts have pH = 7, Equilibrium occurs when [reactants] = [products], Changing temperature has no effect on equilibrium,
