1. Phosphoric acid ionizes in three steps with their ionization constant values
\(Ka_1\), \(Ka_2\), and \(Ka_3\), respectively,while K is the overall ionization constant.
Which of the following statements are true?A. \(\text{log} K\, =\, \text{log} Ka_1\, + \,\text{log}Ka_2\, +\, \text{log}Ka_3\).
B. \(H_3PO_4\) is a stronger acid than \(H_2PO_4^-\) and \(HPO_4^{2-}\).
ะก. \(Ka_1\) > \(Ka_2\) > \(Ka_3\).
D. \(Ka_1\,= \,\frac{Ka_3\,+\,Ka_2}{2}\).
Choose the correct answer from the options given below:
