In a reaction 1 test tube has CaCl2 mixed with H2C2O4, HCl and NH3. After adding the NH3 into the oxalate acid solution was the precipitate calcium oxalate or calcium hydroxide and how do you know?
(Note in test tube B CaCl2 was mixed with (NH4)2C2O4, when mixed the reaction remained clear and colourless)
Also where would hydroxide ions come from to form hydroxide precipitate (a chemical reaction is necessary)

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...

Part I Color changes of Methyl Violet. We will study the following reaction: HMV (aq) + MV (aq) + H* (aq) yellow greenish-blue violet Step 1. Place about 4 mL of distilled water in a regular test tube. Add two drops of methyl violet indicator. Record the color of the solution. Violet Next, add drop by drop, add 6M HCI. This forces equilibrium to be shifted to the left or right-circle the right answer). Adding HCl changes color from to...
