Explain at what ph will precipitation of al(oh)3

Reference no: EM13250802

The precipitation of aluminum hydroxide, Al(OH)_3 (K_sp)=1.3 x 10^{-33}), is sometimes used to purify water.

At what pH will precipitation of Al(OH)_3 begin if 5.70 lb of aluminum sulfate, Al_2(SO_4)_3, is added to 2050 gallons of water (with a negligible change in volume)?

Below are some potentially useful conversion factors.

1 lb = 453.6 g
1 gallon = 4 quarts
1 quart = 0.946 L
