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.
