Why the colour of Turmeric is changedto pink or red by reaction with concentrated Sulphuric Acid?
The color change of turmeric to pink or red when it reacts with concentrated sulfuric acid is due to the formation of a complex between curcumin, the active compound in turmeric, and the acid. Sulfuric acid dehydrates curcumin, leading to structural changes that produce colored aromatic compounds. This reaction highlights the sensitivity of curcumin to pH changes and chemical environments, resulting in a vivid color transformation.
What else can I help you with?
What gives when sodium chloride on treating concentrated sulphuric acid?
Any reaction occur.
What did you observe when concentrated sulphuric acid was added to the reaction mixture?
I think it makes the equation to be more balanced
What is the reaction of hexane in sulphuric acid?
Hexane does not react with concentrated sulphuric acid under normal conditions. However, if heated strongly, it may undergo dehydration to form alkenes.
What occurs when copper reacts with dilute sulphuric acid?
When copper reacts with dilute sulphuric acid, copper sulfate and hydrogen gas are produced. The copper sulfate formed will be a blue solution. This reaction is a redox reaction, where copper is oxidized and hydrogen is reduced.
What happens when you mix water and sulphuric acid?
when we add water n sulphuric acid then dilute sulphuric acid is formed. But we have to mix concentrated acid to water not water to acid otherwise the container in which u r mixing may explode because this reaction is highly exothermic.
What happens when formic acid reacts with concentrated sulphuric acid?
When formic acid reacts with concentrated sulfuric acid, a dehydration reaction occurs, resulting in the formation of carbon monoxide and water as products. This reaction is a type of dehydration reaction known as a Fischer esterification.
What happens when boron react with concentrated sulphuric acid?
When boron reacts with concentrated sulfuric acid, it forms boron trioxide (B2O3) and sulfur dioxide (SO2) as products. The reaction is characterized by the formation of a white, powdery solid of boron oxide, along with the release of heat. Additionally, concentrated sulfuric acid acts as an oxidizing agent, facilitating the oxidation of boron during the reaction.
Why is sulphuric acid not used in preparation of carbondioxidei?
because sulphuric acid stops reaction
What happens when sulphur reacts with hot and concentrated sulphuric acid?
When sulfur reacts with hot and concentrated sulfuric acid, sulfur dioxide gas is produced. This reaction is exothermic and can be quite vigorous. The sulfur dioxide gas can further react with the sulfuric acid to form additional products depending on the conditions.
How do you get back the color of turmeric after the reaction of turmeric and calcium hydroxide solution?
add lemon juice
What reaction takes place when turmeric is mixed with lemon juice?
Turmeric is yellow in an acidic solution.
What is the chemical equation for reaction between viscose solution and sulphuric acid?
write chemical equation for the reaction between viscose solution and sulphuric acid
