using a buret, add 1, 5, 10, and 15mL of standardized 0.0024 M K2CrO4 to each of four clean, dry 100-mL volumetric flasks and dilute to the 100 mL mark with 0.25 M NaNO3. Calculate the CrO4 2- concentration in each of these flasks

Expert Solution

given Ksp = [Ag+ ]^ 2 [CrO4 2- ]

=> Initial [CrO4 2- ] = 0.0024 M

K2CrO4(s)== 2K+(aq)+ CrO42-(aq)

volume of 0.0024M [CrO4-]

K2Cr2O4

1ml 2.4 x 10-5

5ml 1.2 x 10-4

10ml 2.4 x 10-4

15ml 3.6 x 10-4

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...
