Four solutions at 298 K: P ; Q weak acid HA, ionised; R ; S (). Which statements are correct?

  1. AR and S have the same pH.
  2. BThe pH of Q is .
  3. CEqual volumes of P and R give a neutral solution (pH ).
  4. DThe pH of P is higher than that of Q.

Answer: A, B, C

R: ; S: , so both have pH . Q: , pH . Equal volumes of strong acid and base of equal molarity neutralise exactly, pH . P (pH ) is lower than Q (pH ), so option 4 is false.
