What color does Benedicts solution turn when mixed with simple sugars?
Benedict's solution turns brick red when mixed with simple sugars like glucose, fructose, or maltose. This color change indicates the presence of reducing sugars in the solution due to the reduction of copper ions in the Benedict's solution.
What substance turns Benedicts solution blue?
Benedict's solution turns blue in the presence of oxygen. When heated with reducing sugars like glucose, it changes color from blue to green, yellow, orange, red, or brown, depending on the amount of sugar present.
What gas that passed through into an acidic dichromate solution and turn the solution from orange to green?
Sulfur dioxide gas passed through an acidic dichromate solution turns the solution from orange to green.
What colour is universal indicator solution when you put acid in?
Universal indicator solution turns a shade of red, orange, or yellow when added to an acidic solution.
What is the colour change in the titration of KOH with H2SO4 using methyl orange as the indicator?
The titration starts with the solution being yellow due to the presence of excess base (KOH). As the acid (H2SO4) is added, the solution turns from yellow to orange as the pH drops. Finally, the solution changes from orange to pink when all the base has been neutralized by the acid.
What is the indicator for carbohydrates?
Simple(sugar): benedicts solution. Turns bright orange. Complex(starch): iodine turns dark purple/black
What is the name of the product which colourless solution turns orange?
The product you are referring to is likely iodine. Iodine is a chemical element with a colorless solution that turns orange when it comes into contact with starch.
Which white powder turns blue-black in iodine solution?
Starch powder turns blue-black in iodine solution due to the formation of a starch-iodine complex.

Benedict's solution turns blue in the presence of oxygen. When heated with reducing sugars like glucose, it changes color from blue to green, yellow, orange, red, or brown, depending on the amount of sugar present.
What gas that passed through into an acidic dichromate solution and turn the solution from orange to green?
Sulfur dioxide gas passed through an acidic dichromate solution turns the solution from orange to green.
If we prepare a Colloidal solution of milk powder or starch in water what answer will we get?
the solution turns white and light gets diffracted after passing through it.
What happens when iodine and baking powder mix?
it turns the color orange green and black + hard and became sticky.
What colour is universal indicator solution when you put acid in?
Universal indicator solution turns a shade of red, orange, or yellow when added to an acidic solution.

If benedicts reagent turns red what substance is present?
If Benedict's reagent turns red after adding it to a solution, it indicates the presence of reducing sugars such as glucose or fructose. The red color is a result of the reduction of copper (II) ions in the reagent to copper (I) oxide by the reducing sugars.
What are the steps for conducting starch test on given sample of rice grain?
Crush the rice grain into a powder. Add a few drops of iodine solution to the powder. If the iodine solution turns blue-black, it indicates the presence of starch in the rice grain.
