1. Methyl orange, HMO, is a common acid-base indicator. In solution it ionizes according to the equation: HMO(aq) = H(aq) + MO"(aq) red yellow If methyl orange is added to distilled water, the solution turns yellow. If a drop or two of 6 M HCl is added to the yellow solution, it turns red. If to that solution one adds a few drops of 6 M NaOH the color reverts to yellow a. Why does adding 6 M HCl to...

Part III. Single Replacement. With the following reactions, evidence of a reaction may not be immediately apparent. Before making a decision be sure to let the reaction stand for approximately 10 minutes. If no reaction occurs, write, "NO RXN" in under balanced chemical equations; Do not Wrile products or other equations. 1. Fill a test tube half full with DI water and place it behind the safety shield in the hood. Sodium metal is stored under a non-reactive solvent such...
