Acids and Bases Exercise: (a)What is the conjugate base of HClO 4, H 2 S, PH 4 +, HCO 3 ? (b)What is the conjugate acid of CN , SO 4 2 , H 2 O, HCO 3 ?
Acids and Bases Exercise: The hydrogen sulfite ion (HSO 3 ) is amphiprotic. Write an equation for the reaction of HSO 3 with water (a) in which the ion acts as an acid and (b) in which the ion acts as a base. In both cases identify the conjugate acid–base pairs.
Acids and Bases Exercise: Calculate the concentration of H + (aq) in (a) a solution in which [OH ] is 0.010 M, (b) a solution in which [OH ] is 1.8 10 9 M. Also calculate the pH values for the both solutions. Note: In this problem, we assume, unless stated otherwise, that the temperature is 25 C.
Acids and Bases Exercise: A sample of freshly pressed apple juice has a pOH of 10.24. Calculate [H + ].
