The solubility product of calcium fluoride (CaF2) is 3x10^-11. If water contains 300 mg/L calcium, how much fluoride will be soluble?
please show work
Each of the insoluble salts below are put into 0.10 M hydrochloric acid solution. Do you expect their solubility to be more, less, or about the same as in a pure water solution ?
silver chloride More soluble than in pure water.
barium fluoride Similar solubility as in pure water.
lead bromide Less soluble than in pure water.
calcium sulfite
