1) 20.0 mL of 0.01 M AgNO3 and 30.0 mL of 0.010 M K2CrO4 are
mixed together and allowed to react. Will a precipitate form? What
will be the molarities of the silver ion and chromate ion at
equilibrium?
2) Tooth enamel is composed of hydroxyapatite, whose simplest
formula is Ca5(PO4)3OH and whose corresponding Ksp = 6.8 x 10^-27.
As discussed, fluoride in fluorinated water or in toothpaste reacts
with the hydroxyapatite to form fluoroapatite, Ca5(PO4)3F whose Ksp
= 1.0...
