The reaction was stopped before all the nickel reacted, and 36.5 g of solid metal (nickel and silver) is present. Make sure you have theĪ 21.5 g sample of nickel was treated with excess silver nitrate solution to produce silver metal and nickel(II) nitrate. Calculate the mass of silver nitrate present in the first solution.

2.89 g of precipitate is produced (assume silver chromate). Calculate the mass of silver chloride in grams required to make 4.7 g of silver plating.Ī technician mixes a solution containing silver nitrate with a solution containing sodium chromate. Silver chloride, often used in silver plating, contains 75.27% Ag. Using the same initial set up of 10mL of 1M silver nitrate is combined with 25mL of 0.1M sodium chromate, what is the reaction quotient (Q) of the silver chromate? (Is a precipitate going to form?) The Ksp for silver chromate (Ag2CrO4) is 1.1x10-12. What will be the concentration of Ca^2+ (aq) when Ag2SO4(s) begins to precipitate? What percentage of the Ca^2+ (aq) can be separated from the Ag^+ (aq) by

Sodium sulfate is slowly added to a solution containing 0.0500 M Ca^2+ (aq) and 0.0390 M Ag^+ (aq). I need help with a few more btw to double check if i'm doing these right. What is the solubility of Ag2SO4 if the Ksp of Ag2SO4 is 1.4 × 10-5? 7.4 × 10^-3 M 1.5 × 10^-2 M 2.4 × 10^-2 M 3.7 × 10^-3 Mģ.) Calculate the mass of oxygen gas that can be produced in the decomposition of 5.55 g of silver oxide. How long would it take in minutes to plate 1.00 gram of silver to a watch when 9.2 amps are passed through a silver (I) chloride solution? (atomic mass of silver is 107.8682 g/mol).
