Because of the toxicity of mercury compounds, mercury(I)chloride is used in antibacterial salves. The mercury(I) ion (Hg22+ ) consists of two bound Hg+ ions.
a. What is the chemical formula of mercury(I) chloride? (1mark)
b. Calculate [Hg2 2+ ] in a saturated solution of mercury(I)chloride (Ksp = 1.5 x 10-18 ).
c. Seawater contains 0.03 kg of NaCl per litre. Using a suitableapproximation, find [Hg2 2+ ] if the seawater is saturated withmercury(I) chloride.
d. How many grams of mercury(I) chloride are needed to saturate4900 km3 of water (the volume of Lake Michigan)? e. Howmany grams of mercury(I) chloride are needed to saturate 4900 km3of seawater?
