A chemist attempts to seperate barium ions from lead ions by using the sulfate ion as a precipitating agent.

a) What sulfate ion concentrations are required for the precipitation of BaSO4 and pbSO4 from a solution containing 0.010M Ba^2+ aq and 0.010M Pb^2+ aq?

b) What is the concentration of barium ions when the lead sulfate begins to precipitate?

Barium Sulfate can be made by mixing solutions containing thebarium and sulfate ions. The net ionic equation for this reactionis Ba2+(aq) + SO4 2-(aq) ----> BaSO4(s). Patient requiring astomach X-ray are often to asked to consume a large container of abarium sulphate suspension ( a mixture of solid barium sulphate andwater) prior to the procedure. This helps to make the stomach andesophagus more visible in the X-ray.Barium ions are toxic butbarium sulphate is safe to consume.
question: which ion is the limiting reagent and which reagent isexcess when barium sulphate is made.?justify your prediction
