A solution contains one or more of the following ions: Ag*, Ca, and Co. Lithium bromide is added to the solution precipitate forms. An excess of lithium sulfate is then added to the solution and a precipitate forms. The precipitate is and lithium phosphate is added to the remaining solution, producing a precipitate. Which ions are present in the original solution? O Ag* O Ca+ Write a net ionic equation for the formation of the precipitate observed after the addition of lithium sulfate. Include physical states.

Based on the reactants phosphoric acid + potassium hydroxide identify the reaction type and how you determined it. Then write and balance the complete reaction including states for every reactant and product.

In the laboratory you are given the task of separating Ag+ and Co2+ ions in aqueous solution.For each reagent listed below indicate if it can be used to separate the ions. Type "Y" for yes or "N" for no. If the reagent CAN be used to separate the ions, give the formula of the precipitate. If it cannot, type "No Y or N Reagent Formula of Precipitate if YES 1. fill in the blank 1 NaOH   2. fill in the blank 3 Na2CO3   3. fill in the blank 5 NaI

A barium hydroxide solution is prepared by dissolving 3.22 g of Ba(OH), in water to make 58.1 mL of solution. What is the concentration of the solution in units of molarity? concentration: The barium hydroxide solution is used to titrate a perchloric acid solution of unknown concentration. Write a balanced chemica equation to represent the reaction between barium hydroxide and perchloric acid. chemical equation: If 18.5 ml of the barium hydroxide solution was needed to neutralize a 8.04 mL aliquot of the perchloric acid solution, what is the concentration of the acid? concentration:

Chromium(III) ions are very poisonous. They can be removed from solution by precipitating very insouble chromium(III) hydroxide. Chromium(III) chloride reacts with calcium hydroxide to form chromium(III) hydroxide and calcium chloride.   Write the balanced formula unit equation for the reaction stated above. Now, determine the total ionic equation for the reaction stated above. Now write the balanced net ionic equation for the reaction stated above.

79. A solution contains an unknown mass of dissolved barium ions. When sodium sulfate is added to the solution, a white precipitate forms. The precipitate is filtered and dried and found to have a mass of 258 mg. What mass of barium was in the original solution? (Assume that all of the barium was precipitated out of solution by the reaction.)
