If 65.27g of precipitate is actually recovered, what is the percentageyield?What mass of silver nitrate will precipitate out of solution if 950.0g of silver nitrate is initially dissolved into 225 g of water at 50oC and then the solution is cooled to 20oC?The solubility of TlCl [thallium(I) chloride], an intermediate formed when thallium is being isolated from ores, is 3.46 grams per liter at 20 °C. What is its solubility product?
- Imagine an experiment in which the percentage of manganese, Mn, in a manganese ore is to be determined by gravimetric analysis. If 0.8423g of the more yielded 0.3077g of Mn3O4 precipitate what is the percentage Mn in the oreIt is sometimes asserted that carbonates are soluble instrong acids because a gas is formed that escapes (CO2).Suppose that CO2 were extremely soluble in water (as, forexample, ammonia is) and therefore it did not leave thesite of the reaction, but that otherwise, its chemistry wasunchanged. Would calcium carbonate be soluble in strongacids? Explain.If a gas has a solubility of 0.85g / L at 25°C and 425 kPa, what will its solubility be at a pressure of 200 kPa and the same temperature?
- You are designing a process to remove carbonate ions from an aqueous system by precipitation.

Explain your answer. Salt Ksp CaCO3 4.8109 FeCO3 3.51011 PbCO3 1.51013 Ag2CO3 8.21012Tooth enamel is composed of hydroxyapatite, whose simplest formula is Ca5(PO4)3OH, and whose corresponding Ksp = 6.8 * 10-27.

K, of Fe(CN)g3- is 4.0 x 1043.
