A hydraulic fracturing water sample has high concentration of salts. Among various salts dissolved in it, Strontium (Sr) is one of the big concerns because of its radioactivity. A scientist is trying to use precipitation reaction to remove Sr2+ from hydraulic fracturing water sample. As he found, SRSO4 has low solubility, with a Ksp of 107.53, given the hydraulic fracturing water ionic strength of 1.23, at what concentration (in mg/L) the SO,2 needs to present in hydraulic fracturing water in order to lower the Sr2+ concentration to 100 mg/L. Note: the atomic weight of Sr is 88.

The Handbook of Chemistry and Physics (http://openstaxcollege.org/l/16Handbook) gives solubilities of the following compounds in grams per 100 mL of water. Because these compounds are only slightly soluble, assume that the volume does not change on dissolution and calculate the solubility product for each. (a) BaSiF6, 0.026 g/100 mL (contains SiF62- ions) (b) Ce(IO3)4, 1.5102 g/100 mL (c) Gd2(SO4)3, 3.98 g/100 mL (d) (NH4)2PtBr6, 0.59 g/100 mL (contains PtBr62- ions)
15). If Ca(NO3) (aq) is slowly added to solution containing CO32– and SO42– what compound would precipitate out first given the solubility products (Ksp (CaSO4) = 2.4 x 10–5 and Ksp (CaCO3) = 8.7 x 10–9)? CaCO3 would precipitate first because it is least soluble. CaSO4 would precipitate first because it is least soluble. CaCO3 would precipitate first because it is more soluble. CaSO4 would precipitate first because it is more soluble.
