Question

Can someone explain in detail how to do these problems? Youcan answer them as separate posts if you want more points. 1a. For Ag3Po4, the measured "s" at 25oC is 6.7 x10-3 g/L and Ksp(Ag3PO4) = 2.8x 10-18.Assuming "s" is correct, show the calculations that prove that thisKsp value is not correct. b. Use Ksp(Ag3PO4) = 1.3 x 10-20 and s = 6.7 x10-3 g/L to calculate [PO4-3] forsaturated aqueous Ag3PO4 soln at 25oC. Then calculatepercent hydrolysis for PO4-3. c. Comment of the calculated percent hydrolysis. Is it toolow, too high, or reasonable? Why? Can someone explain in detail how to do these problems?

Explanation / Answer

ksp of a compound let AxBy is given by (xs)x(ys)y where s is the solubilty so here x= 3 and y = 1 so ksp = 33* (6.7 x 10-3 g/L)4               = 5.4408 * 10-8 so ksp value given is wrong
