2. The colorless solution of an unknown solid turned red litmus blue. No odor was noted upon adding NaOH. A gray-white precipitate formed upon adding AgNO, and a white precipitate formed upon adding Pb(NO),. The flame test gave a violet color, and bubbles formed after adding HCl. Identify the unknown from the list of possibilities in the Introduction to this experiment.

Perform these calculations for nickel(II) carbonate. (a) With what volume of water must a precipitate containing NiCO3 be washed to dissolve 0.100 g of this compound? Assume that the wash water becomes saturated with NiCO3 (Ksp = 1.36 × 10–7).(b) If the NiCO3 were a contaminant in a sample of CoCO3 (Ksp = 1.0 × 10–12), what mass of CoCO3 would have been lost? Keep in mind that both NiCO3 and CoCO3 dissolve in the same solution.

In this activity, you will develop an experimental procedure to solve a problem. Consider the followingscenario:You are the manager of a chemical stockroom, and find a bottle containing approximately one liter of aclear and colorless solution of unknown identity and concentration. Your only clue to its identity is thatit was found between bottles of silver fluoride and sodium fluoride, so it is likely an aqueous solution ofone of those two compounds. You will need to develop a procedure to determine the following:a) The identity of the unknown solutionb) The concentration of the unknown solutionWrite out a precise procedure, which includes all glassware, reagents, and steps. You will also need towrite the calculations that you would need to determine the concentration of the solution. Assume thatyou have access to any reagent you might need

1. The substance to be analyzed – is white, highly soluble in water salt. When interacting with concentrated sulfuric acid – evolving of some odorless and colorless gas is observed. Reaction with diluted acids or NaOH solution doesn’t lead to any precipitation. Interaction with Nessler's reagent leads to formation of reddish-brown precipitate. Addition of barium chloride solution leads to appearance of white precipitate, which soluble in acetic acid. What kind of salt is this? Explain you answer, provide chemical equations
