1. I placed 5 mL of 0.025 M CuSO4 in a test tube, and slowly added 15 M NH3 until my solution turned blue, I then removed reactant by adding (CuSO4, NH3, H20, HCl, NaOH) and my test tube appeared clear, light light blue. That's because as I removed reactant, the Cu2+ concentration (increased, decreased, stayed the same) 2. In a medium test tube, I added 2 drops of 6 M NaOH to 5 mL of 0.05 M MgCl2(aq) to...

1. In a small beaker mix together 5.0 mL of 0.10 M Co(NO3)2 . 6H2O with 5.0 mL of concentrated HCl. Be sure to mix thoroughly with your glass stirring rod. This is your equilibrium mixture. 2. Place 1.0 mL of your equilibrium mixture in a small test tube add 1.0 mL of concentrated HCl. Observe any color changes and state in which direction (if any) the equilibrium shifted. Place a new 1.0 mL sample of your equilibrium mixture in...

(b) Saturated Barium Chromate. Watch Video-3b where to 3 mL of 0.1 M BaCl2, 5-6 drops of 1 MK2CrO4 are added, and then 10 to 12 drops of 6 M HCI. Write down the chemical reaction(s) involved (you might look back at Part la), being sure to include the state of matter of all reactants and products so it is clear if there is a solid/precipitate expected.

Experiment 8 Solubility of lonic Precipitates Lead chloride is a slightly soluble salt. When lead chloride dissolves in pure water or an aqueous solution, the small quantity that dissolves completely ionizes and reaches equilibrium in a saturated solution, PbCl(s) ® Pb (aq) + 2Cl(aq) Kp = [Pb (C) (1) Lets be the molar solubility of lead chloride. In pure water, s = [Pb ) = (CH) / 2. In a solution containing Cl, a common ion to lead chloride, s...
