What color is sugar on the pH scale?

Answer 1

The pH scale is numeric and has no inherent colors. Various indicators have different colors and operate over different ranges; for example, phenolphthalein turns pink at high pH and is colorless in acidic or neutral solutions, but litmus is pinkish in acid solutions and blue in basic solutions.

Answer 2

This question does not describe the test- or experimental method (Benedict's, Fehling's, Silvertest) and which kind of sugar is to be tested: monosaccharides (glucose, fructose) or table sugar (sucrose), reducing or non-reducing.

Benedict's test is on reducing sugars like glucose, mannose and the non-reducing alpha-hydroxy-ketone fructose;

Negative results are obtained with non-alpha-hydroxy-ketone-sugars.

Important:

Though sucrose is a disaccharide containing glucose and fructose, they are joined by a glycosidic bond between their respective aldehyde and keto groups, which does ONLY hydrolyse with acid, not with soda in Benedict's test.

Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent

Color change B's test: red-green-yellow

Answer 3

sugar does not change the pH of a solution, so if a sugar solution would be neutral but for color you have to check what indicator you are using and the color for neutralthe pH is 0.5

Answer 4

The most common test is with Benedict reagent; the color depends on the concentration of sugar (green, yellow, red).

Answer 5

Sugar is neither acidic nor basic on the pH scale. It is neutral with a pH value around 7.

Answer 6
