Apply Describe the reaction of aqueous solutions of sodium sulfide and copper(ll) sulfate, producing the precipitate copper(ll) sulfide.

In a dilute solution of sodium chloride in water, the sodium chloride is the: a. solvent. b. solute. c. precipitate. d. reactant.

Certain vegetables and fruits, such as potatoes and apples, darken quickly when sliced. Submerging the slices in water slows this process. Explain.

Apply Students conducted a lab to investigate limiting and excess reactants. The students added different volumes of sodium phosphate solution (Na3PO4) to a beaker. They then added a constant volume of cobalt(ll) nitrate solution (CO(NO3)2) stirred the contents, and allowed the beakers to sit overnight. The next day, each beaker had a purple precipitate at the bottom. The students decanted the supernatant from each beaker, divided it into two samples, and added one drop Of sodium phosphate solution to one sample and one drop of cobalt(ll) nitrate solution to the second sample. Their results are shown in Table 11.5. a. Write a balanced chemical equation for the reaction. b. Based on the results, identify the limiting reactant and the excess reactant for each trial.

An analytical procedure for finding the chloride ion concentration in a solution involves the precipitation of silver chloride: Ag++ClAgCl. What is the molarity of the chloride ion if 16.80mL of 0.629M silver nitrate the source of silver ion is needed to precipitate all of the chloride ion in a 25.00-mL sample of the unknown? Silver nitrate solution is added to an unknown chloride-ion solution, yielding a precipitate of silver chloride.

A solution containing 1.63g of barium chloride is added to a solution containing 2.40g of sodium chromate chromate ion, CrO42. Find the mass in grams of barium chromate that can precipitate. Also determine which reactant was in excess, as well as the mass in grams in excess of the amount required by the limiting reactant.

Complete the missing information in the following skeletion equation and balance the chemical equation: NaOH(aq)+3NaCl(aq)+Al(OH)3(aq)

A student weighs out a 4.80-g sample of aluminum bromide, transfers it to a 100-mL volumetric flask, adds enough water to dissolve it, and then adds water to the 100-mL mark. What is the molarity of aluminum bromide in the resulting solution?

A student was given a 1.6240-g sample of a mixture of sodium nitrate and sodium chloride and was asked to find the percentage of each compound in the mixture. She dissolved the sample and added a solution that contained an excess of silver nitrate. The silver ion precipitated all of the chloride ion in the mixture as silver chloride. It was filtered, dried, and weighed. Its mass was 2.056g. What was the percentage of each compound in the mixture?
