Which of the following relationship is correct?
Correct answer: D. None of these
- A. Ka = 1/Kb
- B. Ka = Kb
- C. pKw = log Kw
- D. None of these
Explanation
The correct answer is 'None of these' because none of the provided relationships reflect the true mathematical expressions involving dissociation constants. The accurate relationship for a conjugate acid-base pair is Kw = Ka * Kb. Additionally, pKw should be expressed as -log Kw, not log Kw. Thus, options A, B, and C are incorrect.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.

Suppose Kb value for HSO4- is 1 x 10^-9 what is the Ka value for H2SO4?
The strength of a mixture of HCl & H2SO4 is 0.1 N. On treatment with an excess of AgNO3 solution, 20 ml of this acid mixture gives 0.1435 gm of AgCl. The strength of the H2SO4 is:
