Question

Ka1 ,Ka2 and Ka3 are the respective ionisation constant for the following​

Answer 1

Question: Ka1 , Ka2 and  Ka3 are the respective ionisation constants for the following reactions. H2S ⇄ H+ + HS– HS– ⇄ H+ + S2– H2S ⇄ 2H+ + S2– The correct relationship between Ka1 , Ka2 and Ka3 is (i) Ka3 = Ka1 × Ka2 (ii) Ka3 = Ka1 + Ka2 (iii)  Ka3 = Ka1 - Ka2 (iv)  Ka3 = Ka1 / Ka2. Answer: (i) Ka3 = Ka1 × Ka2.
