(choose chapter or problem)

Because of the toxicity of mercury compounds, mercury(I) chloride is used in antibacterial salves. The mercury(I) ion (Hg2 2?) consists of two bound Hg? ions. (a) What is the empirical formula of mercury(I) chloride? (b) Calculate [Hg2 2?] in a saturated solution of mercury(I) chloride (Ksp 1.5?10?18). (c) A seawater sample contains 0.20 lb of NaCl per gallon. Find [Hg2 2?] if the seawater is saturated with mercury(I) chloride. (d) How many grams of mercury(I) chloride are needed to saturate 4900 km3 of pure water (the volume of Lake Michigan)? (e) How many grams of mercury(I) chloride are needed to saturate 4900 km3 of seawater?
