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...

Hi, can anyone please help me with this? i have no clue how to define if a reaction is Oxidation reduction or not. Thanks a lot OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
