The universe as a whole does not have a specific colour. However, in a science experiment, when an antacid solution is added to a universal indicator, it may change colour based on the pH level of the solution. This change in colour signifies the acidity or alkalinity of the solution.
breaks down sucrose into glucose and fructose
The color change that occurs when iodine solution is added to starch is a dark blue or purple color. This reaction is commonly used to test for the presence of starch in a solution.
Potato turns blue or purple when Benedict's solution is added, indicating the presence of reducing sugars such as glucose. This color change occurs due to the chemical reaction between the reducing sugars in the potato and the copper ions in the Benedict's solution.

The color change in glucose when Benedict's solution is added and heated is from blue to green, yellow, orange, or red, depending on the concentration of glucose present. This color change occurs due to the reduction of cupric ions in Benedict's solution by the glucose molecules, forming a colored precipitate.
The reacting sucrose solution color will depend on the concentration of the sucrose in solution. The higher the concentration, the darker the color: green is the least concentrated, to yellow/orange, red, and brown with the highest concentration.
It causes the reaction to speed up showing more simple sugar in a solution, faster than just letting it sit.
A neutral solution added to universal indicator will turn green.

u add equal amounts of solution you want to test and bendict and heat until no colour change is seen then follow these colours. BlUE=> GREEN=> YELLOW=> ORANGE=> BrICKRED NO GLUSOE LESS concentration mild concentration high concentration VERY high concentration
Na2CO3 is added to the solution before the Benedict's test to create an alkaline environment, which helps to stabilize the blue copper (II) ions in the Benedict's reagent. This stabilization is important for the detection of reducing sugars, as the copper (II) ions must be reduced to form a red precipitate in the presence of reducing sugars.
