The determination of cyanide ions (CN-) is carried out according to the Mohr method: a titrating solution of silver nitrate (AgNO3) is gradually added to the aqueous sample until a red precipitate corresponding to the silver (I) chromate (Ag2CrO4) appears. To observe the titration end point, a small amount of Sodium Chromate is added to the aqueous sample. From the solubility product of Ag(CN)(s), calculate the maximum concentration of Ag+ ions allowed in solution in equilibrium with the solid phase.

As part of the analysis of water samples, the hardness of water is commonly measured and calculated. It is commonly expressed in ppm by mass (parts per million) of CaCO3. Parts per million is also equivalent to milligrams of CACO3 per liter of water. In a sample taken by an environmentalist, he was able to observe a hardness count of 205 mg CacO3/L. Given this hardness count of the sample, what is the molar concentration of Ca2+ ions in the water sample?
The solubility of lead(II) fluoride, PbF2, in pure water is 2.1 × 10–3 moles per liter. Calculate the value of Ksp for lead(II) fluoride from this data.
The solubility of Ca(OH)2 is measured and found to be 0.912 g/L. Use this information to calculate a Ksp value for calcium hydroxide.
We began the chapter with an informal discussion of how the mineral fluorite (as shown) is formed. Fluorite, CaF2, is a slightly soluble solid that dissolves according to the equation: CaF2(s) ⇌ Ca2+(aq) + 2F−(aq)The concentration of Ca2+ in a saturated solution of CaF2 is 2.15 × 10–4 M; therefore, that of F– is 4.30 × 10–4 M, that is, twice the concentration of Ca2+. What is the solubility product of fluorite?
(TOPIC: Gravimetry multi-component analysis) A 0.8612-g sample of a mixture of sodium bromide, sodium iodide, and sodium nitrate is analyzed by adding silver nitrate and precipitating a 1.0186-g mixture of silver bromide and silver iodide. The precipitate is then heated in a stream of chlorine gas, which converts it to 0.7125 g of silver chloride. Calculate the %w/w nitrate in the sample.
Write the Ksp expression for the solubility of potassium bitartrate at room temperature and describe how the Ksp for the solubility of potassium bitartrate changes as the solution is heated to its boiling point.
To determine the fluoride content in an aqueous and chloride-containing preparation of ammonium fluoride, the following analysis was performed. 105.2 mg of the preparation was dissolved in 100.0 mL of water. Then a 300 mL 40 mM lead chloride solution was added, whereby all fluoride ions were precipitated out of the solution in the form of the sparingly soluble salt PbClF (s). The precipitate was separated and washed at 15 degrees with a lead fluoride chloride saturated solution and dried at 130 degrees. The precipitate weighed 651.3 mg. a) Calculate the fluoride content (as % by weight F) in the preparation.b) Determine the purity of the ammonium fluoride preparation
