More information is needed to determine the answer to the question asked.7.Kw is which of the following?a. The equilibrium constant for water which is always 1.0 x 10-¹4 @ 25°℃b. ka x kb for conjugate acid - base partners @ 25°Cc. The log [H₂O] @ 25°Cd. Both a and be. none of the above8.For phosphoric acid, H3PO4, the kai expression is:a. [PO4³-][H¹+]³ / [H3PO4]b. [HPO4²-][H¹+] / [H3PO4]c. [H₂PO4¹ ][H¹+] / [H3PO4]d. [H3PO4] / [H₂PO4¹][H¹+]e.
