When an Elodea leaf is added to a phenol red solution, the leaf will release oxygen through photosynthesis. The oxygen will cause the phenol red solution to change color, indicating the presence of oxygen production.

If you added the oxidizing agent chromate to a solution of phenol would the phenol be oxidized and would a green Cr3 plus solution be formed?

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.


What happens to a concentrated solution when a large amount of solventis added to it?

When a large amount of solvent is added to a concentrated solution, the concentration of the solution decreases. This process is known as dilution. The overall volume of the solution increases, but the amount of solute remains the same.


If a base is added to an acidic solution what happens to the ph?

Adding base will increase pH-level


Why phenol does not dissolve in water when excess?

Phenol is slightly soluble in water due to hydrogen bonding between the hydroxyl group of phenol and water molecules. However, when excess phenol is added, it disrupts the hydrogen bonding network of water molecules, making it less soluble. This is because phenol-phenol interactions become stronger than phenol-water interactions, leading to precipitation.


When more solvent is added to a solution what happens to the concentration?

When more solvent is added to a solution, the concentration of the solute decreases. This is because the total volume of the solution increases while the amount of solute remains constant, resulting in a more diluted solution.

tribromophenol is formed.


What will happen to the color of sodium bicarbonate if phenol red is add?

If phenol red is added to sodium bicarbonate, the color of the solution will change based on the pH. In an acidic solution, phenol red will appear yellow, in a neutral solution it will be red, and in an alkaline solution (such as when sodium bicarbonate is added), it will turn a pink or magenta color.

Why Hcl is added in estimation of phenol?

Hydrochloric acid (HCl) is added to the solution during the estimation of phenol to convert phenol into its corresponding chloride salt, which is easier to separate and quantify. This reaction helps in the extraction and analysis of phenol from the sample.


What happens when bromine water is added to phenol?

tribromophenol is formed.


What happens when you add phenol red indicator to calcium chloride?

When phenol red indicator is added to calcium chloride, there won't be any specific chemical reaction between the two. Phenol red is commonly used as a pH indicator, changing color based on the acidity or alkalinity of a solution. However, since calcium chloride does not significantly affect the pH of a solution, the color of phenol red may not change in this case.


What happens when a solute is added to an unsaturated solution?

It will dissolve in the solution.


What the importance of adding sodium carbonate in phenol content determination?

Sodium carbonate is added in phenol content determination to help neutralize the acidic phenol solution, making it less acidic. This step allows for accurate measurement of phenol content by stabilizing the pH level of the solution. Additionally, sodium carbonate helps in the formation of a colored complex with phenol, which can be easily measured and quantified.

Does phenol red change baking soda to red?

Phenol red is a pH indicator that changes color in response to pH changes. It turns yellow in acidic conditions and red in basic conditions. When added to a solution containing baking soda (sodium bicarbonate), which is a basic substance, phenol red can turn red.
