If you omitted methyl red in the reaction mixture, you would not be able to visually monitor or detect the pH change in the reaction. Methyl red is a pH indicator that changes color in response to pH changes, so without it, you would not be able to accurately determine when the reaction has reached a specific pH endpoint.
Yes, if chromate is added to a solution of phenol, the phenol can be oxidized. Chromate (CrO4^2-) acts as an oxidizing agent, converting phenol into various oxidized products, such as quinones. During this reaction, the chromate ion is reduced to Cr³⁺, which is typically a green solution. Thus, the presence of a green Cr³⁺ solution indicates that the oxidation of phenol has occurred.
A positive Lucas test on phenol would indicate that phenol is a strong enough acid to react with Lucas reagent (a mixture of concentrated hydrochloric acid and zinc chloride) to form a cloudy solution or a precipitate. This reaction distinguishes phenol from other alcohols that do not react with the Lucas reagent.
The reaction would shift to balance the change
Cresol is a derivative of phenol. It is an organic compound with a similar structure to phenol, but with a methyl group attached to the benzene ring.
Without phenol, the bromine would not have a stable medium for the reaction, leading to a lack of suitable environment for the reaction to occur. Phenol acts as a catalyst in this reaction by providing a stable medium for the formation of the bromine products.

It is impossible a reaction without reactants.
They would be purple.

This reaction distinguishes phenol from other alcohols that do not react with the Lucas reagent.
To convert phenol to 2,4,6-trinitrophenol (picric acid), you would first nitrate phenol by treating it with a mixture of nitric and sulfuric acids. This will lead to the substitution of hydrogen atoms on the phenol ring with nitro groups, resulting in the formation of the 2,4,6-trinitrophenol compound.
If the Na2S2O3 solution were omitted, the appearance of the solution would not change significantly for each kinetic trial. Na2S2O3 is a reagent that acts as a reducing agent and is not directly involved in the appearance of the reaction solution. Its absence would likely affect the reaction rate rather than the visual appearance of the solution.
Hydrogen ions and hydroxide ions are omitted from the net reaction for the hydrolysis of water because they act as both reactants and products in this reversible reaction. Including them would make the reaction appear overly complex. The net reaction focuses on the overall process of water breaking down into hydrogen and hydroxide ions.
