What molar ratio of acetic acid to sodium acetate is required to create a buffer solution at a pH of 4.89 at 25 degree C? Ka for acetic acid is 1.8 X 10-5 A. 2.9 B.0.56 C.1.4 D.0.72 E.0.2 ( I chose this and got is wrong) I'm lost on how to do these problems, but I started ...

Oops, typo. 10,800 = (3600p/100 - p) *** oh, and i just realized, the equation didn't show up when i asked the question. Suppose the cost C of removing p% of the impurities from the waste water in a manufacturing process is given by C(p) = (3600p/100 - p)**

;). Thanks to anyone who tried, but i figured it out on my own. If anyone is interested in the answer.... a) p=100 b) means they can't remove 100% of the impurities. c) 18,00 = (3600p/100 - p) 10,800(100 - p) = 3600p 1,080,000 - 10,800 = 3600p 1,080,000 = 14400p p = 75 rem...
