3. Tris(hydroxymethyl)aminomethane [ (HOCH2)3CNH2, commonly called "Tris" ] is a good non-interacting buffer frequently used with proteins. The pKa value for the protonated form [ (HOCH2)3CNH3* ] is 8.075. The solid salt made with HCl(aq) ("Tris-HCI", the protonated form with a Cl- counter ion) is often utilized to make the buffer - it has a molecular weight of 157.596 g/mole. a. A buffer is made from 15.431 g of solid "Tris-HCI" dissolved in 1000.0 mL of water that contains 0.0462 M NaOH (assume the final volume is also 1000.0 mL). Calculate the pH of this solution. b. Exactly 16.30 mL of 1.761 M HCl(aq) is added to the 1000.0 mL buffer described in part A. What is the new pH?

A solution containing a mixture of metal cations was treated with dilute HCl and no precipitate formed. Next, H, S was bubbled through the acidic solution. A precipitate formed and was filtered off. Then, the pH was raised to about 8 and H, S was again bubbled through the solution. A precipitate again formed and was filtered off. Finally, the solution was treated with a sodium carbonate solution, which resulted in no precipitation. Classify the metal ions based on whether they were definitely present, definitely absent, or whether it is possible they were present in the original mixture. Definitely present Definitely absent Possibly present Ag* Hg²+ Lit Ba²+ Pb2+ Mg²+ Hg3* 2+ Answer Bank Zn2+ Sn2+ Ni2+ Cu2+ Bi3+ A13+ Incorrect
3. To verify the existence of silver in your solution, one should first form a white precipitate by addition of NaCl. Next, the precipitate should dissolve in aqueous ammonia. Silver can re- precipitate by addition of 6M HNO,. Using chemical equations, describe the identity of the product formed in each step.

If you are simul- taneously identifying cations in both a reference solution and a test solution, adjust the procedure accordingly. If the test solution is a sample with an environmental origin, then gravity filter 10-15 mL before beginning the Experimental Procedure. Prepare the hot water bath for use in Parts A and D. 1. Separate the hydroxide precipitates from the amphoteric hydroxides. To 2 mL of the reference solution (in a small test tube) add 10 drops of 6 M NaOH (Caution!) (see Dry Lab 4.A). Centrifuge and save the precipitate. Test for complete precipita- tion (see Dry Lab 4.B) by adding several drops of 6 M NaOH to the supernatant. Decant the…
The colorless solution of an unknown solid turned red litmus blue. No odor was noted upon adding NaOH.
