Develop a sequential analysis to test for the presence of the following sets of ions. The answer you submit should be in the form of a flowchart as we did in class. The flowchart should also include the net ionic equations that show the formation of any precipitate that forms. Phosphate and hydroxide Lead (II) and barium

QUESTION #1: TOPIC: Solving for a reactant in solution  One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe(s) +CuSO4(aq) →Cu(s) +FeSO4(aq) Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 350. mL copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of 93. mg. Calculate the original concentration of copper(II) sulfate in the sample. Round your answer to 2 significant digits.   ? g/L         QUESTION#2: TOPIC: Limiting reactants…
