What color is benedicts solution when mixed with bread?
because it contains glucose
Is iodine an indicator of glucose?
Iodine is not an indicator of glucose. Iodine is primarily used as an indicator for the presence of starch in a solution through the formation of a blue-black color complex. Glucose can be tested using methods such as Benedict's solution, Fehling's solution, or glucose test strips.
What is the color of the fehlings solution?
Fehling's solution is typically blue in color due to the presence of copper ions. When Fehling's solution is mixed with reducing sugars, such as glucose, it turns from blue to brick-red or yellow-brown due to the formation of a copper oxide precipitate.
Why does petrol change color when mixed with iodine solution?
Petrol changes color when mixed with iodine solution due to covalent bonding.
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 color is when NaCl mixed with phenolphthaline?
Nothing it is colourless solution.
What two solutions produce a blue-black color?
When iodine solution is mixed with starch solution they produce blue-black color.
What color is the solution of red cabbage and lemon juice when first mixed?
The color remain red because vinegar is an acidic solution.
What color does saliva turn into with the Benedict's solution?
Benedict's solution changes colors (blue to green to yellow to orange to red) in the presence of "reducing" sugars, which are not normally present in saliva. An interesting experiment, however, is testing table sugar with Benedict's solution. Table sugar is a glucose sugar joined to a fructose sugar, so they cannot react with the Benedict's solution and no color change occurs. Put table sugar in your mouth for a few moments, and then test the saliva. Now the Benedict's solution will react! (The reason: saliva has an enzyme, amylase, which breaks the glucose and fructose apart so that they can react to the Benedict's.)
When testing to determine the presence of carbohydrates specifically simple sugars like glucose in the foods we eat which solution or reagent should be used?
To test for the presence of simple sugars like glucose in foods, the Benedict's reagent is commonly used. When mixed with the sample and heated, a color change indicates the presence of reducing sugars; a blue solution will change to green, yellow, or red, depending on the concentration of glucose. Alternatively, the Fehling's solution can also be used for similar testing.
When blueberry juice is mixed with a solution of baking soda it turns what color?
grey
What color change does bougainvillea juice undergo when mixed with dove solution?
Bougainvillea juice will turn from its original color to pink when mixed with dove solution, due to the presence of anthocyanin pigments in the bougainvillea juice reacting with the alkaline nature of the dove solution.
