HCN(aq) ⇌ H+(aq) + CN-(aq) The ionization constant (Ka) of above acid increases by — AITS & Test Series Chemistry Question

💡 Solution & Explanation

2x + 22x+1 = (y –1) (y +1) Shows that the factors y – 1 and y + 1 are even, exactly one of them divisible by 4. Hence x  3 and one of these factors is divisible by 2x-1 but not by 2x.
