Calculate how many grams of silver chloride will dissolve in 1.0 L of a 1.0 M NH3 solution through formation of the complex ion Ag(NH3)2+.

A solution of barium chromate (BaCrO4)is prepared by dissolving6.3×10−3g of this yellow solid in 1.00 L of hot water. Will solid barium chromate precipitate upon cooling to 25°C, according to the solubility product expression? Explain.

At 100°C, water dissolves 1.8×10-2g of AgCl per liter. Compute the Ksp of AgCl at this temperature.

Question: An aqueous solution of K2Pt(OH)6 has a pH greater than 7. Explain this fact by writing an equation showing thePt(OH)62- ion acting as a Brønsted-Lowry base and accepting a hydrogen ion from water.

Question: Silver iodide (AgI) is used in place of silver chloride for the fastest photographic film because it is more sensitive to light and can therefore form an image in a very short exposure time. A silver iodide emulsion is prepared by adding 6.60 L of 0.10 M NaI solution to 1.50 L of 0.080 M solution at 25°C. Calculate the concentration of silver ion remaining in solution when the mixture comes to equilibrium and its chemical amount relative to the amount present initially
