Schultze's solution turns purple when tested with cellulose due to the presence of iodine in the solution, which forms a complex with the hydroxyl groups in cellulose. This interaction results in a characteristic color change, as the iodine molecules fit into the helical structure of the cellulose, producing a deep purple color. This reaction is commonly used as a qualitative test to confirm the presence of cellulose in various substances.

If you are doing the baeyer test and your solution stays purple what does that mean?

If your solution stays purple during the Baeyer test, it means that no unsaturation (such as carbon-carbon double or triple bonds) is present in the compound being tested. The purple color indicates a negative result for unsaturation.

What is a positive test result for starch?

A positive test result for starch is the formation of a blue-black color when iodine solution is added to the sample being tested. This color change indicates the presence of starch in the sample.


A solution is tested and found to have a pH of 1 the solution is?

The solution is acidic. A pH of 1 indicates a high concentration of H+ ions in the solution, making it strongly acidic.


How can pH of a solution be tested?

By dissolving the pH solution a colour change will occur in the solution that should be tested.Compairing the colour of solution to the colours marked on of pH chart we can find out if the solution we tested is of alkaline nature or of acidic nature or neutral.Solutions of pH7are neutral solutions.Solutions below pH7 are acidic solutions and those above pH7 are alkaline solutions.
