For a solution containing at least one of the Group II cations involved in this experiment, when the solution is acidified to pH 0.5 and H2S is added, a precipitate results. KOH is added to the precipitate. The supernatant liquid is separated from the precipitate and tested with HCl/H2S. A colorless solution results, with no precipitate. Which cation(s) may be present in the original solution tested? (Select all of the possible cations.) Question 2 options: Bismuth Cadmium Copper Tin Save

Question 4 (1 point) Question 4 Unsaved For a solution containing at least one of the Group II cations involved in this experiment, when the solution is acidified to pH 0.5 and H2S is added, a precipitate results. KOH is added to the precipitate. The supernatant liquid is separated from the precipitate and tested with HCl/H2S. A colorless solution results, with no precipitate. The remaining original precipitate was treated with dilute HCl. The supernatant liquid was tested with NH3 and...

An unknown solution may contain some of the cations listed below. One student preformed a series of experiments to determine what ions are in the solution. Based upon the experiments performed by the students, the results are as follows: a) On addition of 6 M HCl, a white precipitate results. The white precipitate is then mixed with NH3 where it dissolves. b) On the addition of 1 ml (20 drops) of 1 M thioacetamide (CH3CSNH2), the test tube was then...

One analyzed an unknown solution containing some of Analytical Group 1 cations (Ag+, Hg2+2, and Pb+2) according to the procedure presented in this experiment. Following was observed: A white precipitate results when an unknown solution is treated with 6M HCl. After washing, 1 mL of distilled water is added, the precipitate is stirred, and the tube is heated in near-boiling water. After centrifuging, the solution is drawn off and set aside. Then the 6M NH3 is added to the precipitate,...

An unknown solution may contain any of the seven cations listed below. One student preformed a series of experiments to determine what ions are in the solution. Based upon the experiments performed by the students, the results are as follows: On addition of 6 M HCl, a white precipitate results. The white precipitate is then mixed with NH3 where it dissolves. b) When acidic H2S is added to the unknown, a black precipitate results, and is dissolved in NH3 giving...

An unknown containing only cations of group III yields, after Step 1, a precipitate and solution. Step 1 B results in the formation of a gray black solid. Treatment with aqua regia ( HCl and hno3 mixture), Step2 leads to a Green Solution. step 3 leads to a deeply colored precipitate. Treatment of the color is supernate with nitric acid, then with aqueous ammonia, does not produce a precipitate. the step 3 precipitate is treated by step for then dissolved...

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean, dry, glass centrifuge tube. 2. Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...
