Question

For a diprotic acid, which of the following is true for first and second ionization constants? (Ka1 and Ka2 ). (A)  Ka1 = Ka2  (B)  Ka1 > Ka2  (C)  Ka2 > Ka1  (D)  Ka2 ge Ka1

For a diprotic acid, further ionization is difficult, therefore K a1 > Ka2

Q. For a diprotic acid, which of the following is true for first and second ionization constants? $(K_{a_{1}}$ and $K_{a_{2}}$ ).

$K_{a_{1}} = K_{a_{2}}$

$K_{a_{1}} > K_{a_{2}}$

$K_{a_{2}} > K_{a_{1}}$

$K_{a_{2}} \geq K_{a_{1}}$

For a diprotic acid, further ionization is difficult,
therefore
$K_{a_{1}} > K_{a_{2}}$

Q. For a diprotic acid, which of the following is true for first and second ionization constants? (Ka1​​ and Ka2​​ ).

Ka1​​=Ka2​​

Ka1​​>Ka2​​

Ka2​​>Ka1​​

Ka2​​≥Ka1​​
