Lead(II) chloride preparation
Preparation: Dissolve 5,00g lead(II) nitrate in 150ml water and slightly with constant stirring add 2,5ml concentrated hydrochloric acid diluted with 30ml water. White product will form. Decant it three times with 100ml water, filter it out and wash with water. Allow to dry at laboratory temperature. Yield is almost theoretical - 4,17g of lead(II) chloride.
Pb(NO3)2 + 2HCl ==> PbCl2 + 2HNO3
Properties: White solid very hardly soluble in water. Another possible preparation is to dissolve PbO in hydrochloric acid. It is used for lead(II) hydroxide-chloride preparation - it is a white paint (Pattinson white). If too much of hydrochloric acid is used, the yield will be small because easy soluble lead complexes will form. Do not wash product with alcohol or you will dissolve it!
