1. Lead based paints have been responsible for poisoning in many cases over years. A
common component is Lead II Carbonate, PbCO3. 535 Litres of a saturated solution of
this compound contains only 25.2 mg of solute in solution. Calculate the Ksp.
2. Strontium compounds are often burned in fireworks to produce a brilliant red colour.
Given that the Ksp of SrF2 is 7.8 x 10-10, what is the solubility of strontium fluoride?
Good Luck...
