What happens when Benedict's solution is heated?
When Benedict's solution is heated, the reduction reaction between the copper (II) ions and the glucose or other reducing sugars present causes the solution to change color from blue to green, yellow, orange, or red, depending on the amount of reducing sugar present. This color change indicates the presence of reducing sugars in the sample being tested.
Why the color of benedicts solution change when heated?
The color change in Benedict's solution when heated is due to the reduction of copper ions in the solution. Initially, the blue-colored Cu(II) ions in Benedict's solution are reduced to form a reddish-brown precipitate of Cu(I) oxide. This color change indicates the presence of reducing sugars in the solution.
What happens when you mix blue litmus paper in bases?
Blue litmus does not change when placed in a basic solution.
How do you think bromothymol blue solution works?
Bromthymol Blue, when heated in a solution, indicates carbon dioxide. If there is carbon dioxide in the solution, it will turn bright yellow (when heated).
What would happen to blue ink if heated?
It would evaporate
When blue crystals are heated is it a physical or chemical change and why?
It would be chemical.
What happens when copper sulphate crystal is heated?
When copper sulfate crystals are heated, they lose their water of hydration and turn into anhydrous copper sulfate, which is a white powder. The color change from blue to white signifies the removal of water molecules.
What colour does hydrous copper sulphate turn when heated?
Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.
What happens when you violate a blue law?
The state confiscates your license.
What normally happens when iodine solution is added to starch?
it will change into blue black colours.
What is the colour of brass when it is heated?
When brass is heated, it can oxidize and change color. It typically starts as a golden-yellow color when cool, then turns to a darker brown or red color as it gets heated, and eventually may develop blue or greenish hues due to oxidation.

Why does copper burn blue?
The chemical change causes the color change when the two new chemicals combine.
