Which white powder turns orange in benedicts solution?
The white powder that turns orange in Benedict's solution is glucose. Benedict's reagent contains copper ions which can be reduced by glucose, resulting in a color change from blue to orange-red.
Why does the indicator goes purple in sodium hydroxide solution?
The purple color in sodium hydroxide solution is an indicator of the presence of phenolphthalein, which turns pink in basic solutions. When phenolphthalein is added to sodium hydroxide solution, it reacts with the hydroxide ions in the solution to form the purple color.
What colour does universal indicator turn in a strong alkaline solution?
Universal indicator turns dark blue or purple in a strong alkaline solution.
Does sodium hydroxide turn litmus solution purple?
yes, it turns in purple or a very light pink-ish purple color
In a basic solution what color does litmus paper turn?
Litmus paper turns blue in basic solution.
What is the indicator for carbohydrates?
Simple(sugar): benedicts solution. Turns bright orange. Complex(starch): iodine turns dark purple/black
When iodine solution is applied to starch it turns?

Universal indicator turns dark blue or purple in a strong alkaline solution.
Why does litmus turn purple?
Litmus paper turns purple in a basic solution due to a chemical reaction with hydroxide ions in the solution. The dye in litmus paper undergoes a change in structure when it comes in contact with a base, causing it to reflect purple light.
Does sodium hydroxide turn litmus solution purple?
yes, it turns in purple or a very light pink-ish purple color
What colour does iodine solution turn when starch is presant?
It turns a dark purple/blue colour
In a basic solution what color does litmus paper turn?

What happens when an onion membrane is put into a vinegar solution?
it turns purple and under a microscope you can see swirlys
When a base and an acid neutralize one another the litmus turns what color?
The color is purple in a neutral solution.
What colour does universal indicator turn in ammonia solution?
Universal indicator turns blue or purple in ammonia solution. Ammonia is a weak base, so it causes the indicator to change to a blue or purple color on the pH scale. This color change indicates the basic nature of the solution due to the presence of ammonia molecules.
