What turn red in glucose solution?
In a glucose solution, the substance that turns red is typically Benedict's reagent when it undergoes a reduction reaction. When heated with a reducing sugar like glucose, the copper(II) ions in Benedict's reagent are reduced to copper(I) oxide, which forms a red precipitate. The intensity of the red color can indicate the concentration of glucose present in the solution.
Is glucose highly volatile?
No. A highly volatile substance is one that easily turns into vapor at or near room temperature. Glucose is quite stable as a solid.
What is formed when water is heated and turns to a gas?
When water is heated and turns into a gas, it forms water vapor.
Orange juice is a beverage that tastes sour and turns litmus paper red What type of substance is it?
Orange juice is acidic because it tastes sour and turns litmus paper red. The acidity is due to the presence of citric acid in the juice, which imparts the sour taste and causes the litmus paper to change color.
Which solid turns yellow on heating?
Sulfur turns yellow when heated.
Benedict's turns orange when heated in the presence of a?
reducing sugar. Benedict's reagent is a solution used to test for the presence of reducing sugars, which includes glucose and fructose. The color change to orange indicates a positive result for the presence of reducing sugars in the substance being tested.
What substance is present when Benedict reagent turns red?
glucose
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.

How can volume change if a substance undergoes a chemical change?
If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.
As a heated liquid turns into a gas it?
As a heated liquid turns into a gas, it ... ?
What is vaporisation?
The process in which a liquid turns into a gas.
If benedicts reagent turns red what substance is present?
If Benedict's reagent turns red after adding it to a solution, it indicates the presence of reducing sugars such as glucose or fructose. The red color is a result of the reduction of copper (II) ions in the reagent to copper (I) oxide by the reducing sugars.
What substance turns Benedicts solution blue?
Benedict's solution turns blue in the presence of oxygen. When heated with reducing sugars like glucose, it changes color from blue to green, yellow, orange, red, or brown, depending on the amount of sugar present.
What is formed when water is heated and turns to a gas?
When water is heated and turns into a gas, it forms water vapor.
How is water heated?
by boling it it turns hot and becomes heated
