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.

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 10-7.53, 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.
