: I 6 A Solution Having A Ph Of 9 00 Contains 0 20 M Of Fluoride Ion F Which Is A Weak Base Find The Ks Of Fluoride Io 2 (27.77 KiB) Viewed 41 times

I 6. A solution having a pH of 9.00 contains 0.20 M of fluoride ion (F) which is a weak base. Find the Ks of fluoride ion. 7. What is the equilibrium concentration of a hypochlorous acid (HCIO) solution with K. - 3.0 x 10 if the pH is 4.10? 8. Acetate ion, CH,COO, has a concentration of 2.0 M. Its Ks is 7.7 x 10³. What is the pH?
9. Lactic acid, HC3H5O3(aq), is a weak acid that gives yogurt its sour taste. Calculate the pH of a 0.0010 M solution of lactic acid. The K₂ for lactic acid is 1.4 x 104. I 10. Ascorbic acid, HC6H-06(ag), is a weak organic acid, also known as vitamin C. A student prepares a 0.20 M aqueous solution of ascorbic acid, and measures its pH as 2.40. Calculate the K, of ascorbic acid.
