What is an indicator for starch and the reaction is?
Iodine is an indicator for starch. The reaction between iodine and starch causes a color change from brown/orange to blue/black.
What is the reaction that occurs when iodine comes into contact with starch?
When iodine comes into contact with starch, a chemical reaction occurs that results in the formation of a dark blue or black color. This reaction is used as a test to detect the presence of starch in a substance.
Is a glowstick a acid or a base?
A glowstick is neither an acid nor a base. It contains chemicals that create light through a chemical reaction when mixed together.
Why is NaOH added in starch iodine test?
In the starch-iodine test, NaOH is added to create an alkaline environment that allows for the formation of the blue-black complex between starch and iodine. This complex is used as an indicator to detect the presence of starch in a sample.
What is the purpose of using starch indicator solution in a chemical reaction?
The purpose of using starch indicator solution in a chemical reaction is to detect the presence of iodine, which can indicate the completion of the reaction or the presence of specific substances.
Why starch is neutral?

Is corn starch a acid base or neutral?
It is a neutral carbohydrate polymere.
How will the time taken for starch to digested in amylase be affected by the temperature?
The time taken for starch to be digested by amylase will decrease as the temperature increases up to an optimal range. This is because higher temperatures speed up enzyme activity. However, if the temperature exceeds the optimal range, the enzyme may denature, leading to a decrease in digestion time.
What is an indicator for starch and the reaction is?
Iodine is an indicator for starch. The reaction between iodine and starch causes a color change from brown/orange to blue/black.
Is starch an acid or base?
i believe Starch is a base, or it can be neutral as well.
Why did iodine stop turning blue-black?
Iodine turns blue-black when it comes in contact with starch because it forms a complex with the starch molecules. If iodine stopped turning blue-black, it could be due to the absence of starch, chemical interference with the reaction, expired iodine solution, or improper storage conditions affecting the reactivity of the iodine.
What is the reaction that occurs when iodine comes into contact with starch?
When iodine comes into contact with starch, a chemical reaction occurs that results in the formation of a dark blue or black color. This reaction is used as a test to detect the presence of starch in a substance.
In which reaction mixture did hydrolysis of starch occur?
The hydrolysis of starch occurs in the reaction mixture containing the enzyme amylase, which breaks down starch into smaller sugars such as maltose and glucose. This process of breaking down starch into simpler sugars is known as enzymatic hydrolysis.
Is a glowstick a acid or a base?
A glowstick is neither an acid nor a base. It contains chemicals that create light through a chemical reaction when mixed together.
What type of reaction takes place when starch molecules are converted into reducing sugars?
The conversion of starch molecules into reducing sugars involves a hydrolysis reaction, where water molecules break the glycosidic bonds in the starch molecules. This process results in the formation of simpler sugars such as glucose, maltose, and maltotriose that are capable of reducing agents like Benedict's reagent.
What is the chemical reaction between lugols solution and a starch?
The reaction between Lugol's solution (iodine) and starch forms a blue-black complex. Iodine molecules fit into the helical structure of starch molecules, producing this characteristic color change. This reaction is commonly used to test for the presence of starch in a solution.
Why HCL only can break down starch at 95?
HCL is a strong acid that can break down starch molecules through hydrolysis at high temperatures like 95 degrees Celsius. This high temperature helps to speed up the chemical reaction between the acid and the starch molecules, resulting in their breakdown. Lower temperatures may not provide enough energy for this reaction to occur effectively.
