Suppose you are asked to determine the identity of a white solid. When you add water to the white solid, it dissolves and forms a clear solution. When you add a solution of Na, so , a white precipitate forms. Add HO Add Na SO Determine the identity of the original solid, OPCI, OCaCI, ZnCl2 MgCl2
< Question 4 of 15 > Suppose you are asked to determine the identity of a white solid. When you add water to the white solid, it dissolves and forms a clear solution. When you add a solution of Na, SO, a white precipitate forms. Add HO Add Na, so Determine the identity of the original solid. O Agi O Srl OKI Nal
Suppose you have an unknown clear, colorless solution. In attempt to identify it, you add NaOH dropwise and find that a white gelatinous precipitate forms, but when more NaOH was added the precipitate dissolved again. To another test tube of the same unknown solution is added AgNO3 dropwise, and a white precipitate forms. What salt most likely comprises the unknown solution? Explain your reasoning (3 points) 2. Suppose you have a different unknown solution that you know to be 50/50...

MgCl2 is white as a solid and colorless if it dissolves in water. HCl is also colorless when it is dissolved in water If Mg is the limiting reagent, at the end of the reaction the solution will be completely transparent but there will be solid MgCl2 at the bottom of the flask. hydrogen gas will continue to bubble through the solution. Adding more HCl will make the reaction start again and produce more product. the solution will be completely...
Lab Section: 1 Prelab: Inorganic Group I Ions 1. On the report sheet, complete the flow diagram for the separation and identification of the ions in Group I 2. Write balanced net ionic equations for the following reactions: The precipitation of the chloride of Pb a. in Step 1. The formation of a yellow precipitate in Step 4. b. The formation of a complex ion in Step 5. c. d. The reaction that forms a white precipitate in Step 5....
1) Suppose you are trying to determine the identity of the metal ions in your unknown mixture for this lab and you find that after step 1 you have a precipitate. You separate the precipitate from the solution and perform step 2 (on the precipitate) and step 3 (on the solution). Your results of step 2 do not yield a precipitate. Your results from step 3 yield a precipitate. Which spot tests should you run to completely determine the identities...
Cold water is added to each of the following pairs of solid salts. In each case state whether a precipitate will be present, and if so what its composition is. Note: The precipitate may be either one or both of the original salts or one or more of the products formed by reaction between the salts. 3. (10 pts) a. Pb(C2H,O2)2 and NaCI b. BaSO4 and Cus c. Ni(NO3)2 and CaCl2 d. AgCl and Cu(NO3)2 e. Na CO, and MgCl2
In the CO 2 test, what is the milky solid (white solid in suspension) that forms in the li solution? Use chemical equations to show the formation of the white solid. 4. In the test for l, you use methylene chloride. How does the density of methylene chloride compare to the density of water? The formation of a yellow precipitate is the confirmatory test for PO. 8. Test for co Figure 1: Test for Carbonate 8.1 Put about 1 mL...
