A student performing this lab experiment receives his unknown solution that may contain ( Ba, Ca, and Mg ). And begins to conduct tests to identify the cations present in the unknown solution. Based on the following observation 1) When the unknown solution was treated with K,Cro,, yellow precipitate was formed. 2) The resulting solution from step 1 was basified with 6M NH, before the addition of aqueous K,C,0, which forms a white precipitate. 3) To the resulting solution from step 2, was treated with ammonia and of Na,HPO, A white precipitate was formed after heating the solution for 10 minutes at 60°C. Which cations were present in the student's unknown solution? Select one or more: 2+ Са 2+ Mg 2+ Ba

4. You are titrating 100.0 ml of a solution containing unknown concentrations of Hg22* and Ba2* (as their soluble nitrate salts) with a solution of 0.134 M NazSO4. BaSO4 is over 1000 times more insoluble than Hg2SO4, so the added S0,² will react with the Hg22* in solution first, before reacting with the Ba* in solution. Below is the titration curve for the addition. The unit on the y-axis is not important. The unit on the x-axis is ml of 0.134 M NazSO4 added. Note the two equivalence points. What are the concentrations of the Hg2* and Ba2* in the 100.0 ml solution? 5 10 15 20 25 30
A saturated solution of an unknown solid reacted with AgNO3 to give a pale yellow precipitate and also reacted with Pb(NO3)2 to give a white precipitate. Based on only these two results, you can conclude that the unknown solid contains which anion? Write the correct balanced equations for the reaction of the anion with each of these reagents.
Which of these anion compounds form a precipitate when added to: 1. AgNO3 ? Or 2. BaCl2 ? ... Anion Compounds: NaCH3COO Na2CO3 NaF NaCl NaBr NaI NaNO3 NaSCN Na2SO4 Na3PO4
1. At a certain temperature, the solubility product constant* of copper (II) iodate, Cu(IO3)2, is 7.17x10-8 M3. Calculate the solubility of this compound for this temperature.*Unless stated otherwise all solubility product constants are for water. 2. Calculate the solubility of copper (II) iodate in 0.21 M copper (II) nitrate. Ksp* is 7.4x10-8M3.*You should know that the Ksp must refer to the copper iodate because all nitrate compounds are soluble and strong electrolytes! 3. What is the initial (before any reaction takes place) lead nitrate concentration when 6.0 mL of 0.171 M lead nitrate is added to 11 mL of 0.0086 M sodium chloride?
