What is the indicator and color change for a positive test for glucose?
Benedict solution is the chemical indicator for simple sugars.
Why does the typical base indicator exhibit its color change over a range of about 2 PH units?
The usual range of the color change on the indicator is between 1.5-2 pH units because of the sensitivity of the indicators. The universal indicator is used in most test.
Which indicator would most likely yield a positive test by way of a color change in the water-cookie solution?
Benedicts solution
What is the indicator used to test for starch hydrolysis?
The indicator used to test for starch hydrolysis is iodine. Iodine reacts with starch to form a dark blue-black color, so if the color change is observed after treating a sample with an amylase (enzyme that breaks down starch), it indicates that starch has been hydrolyzed.
How do you do a test to see if ink is an indicator?
To test if ink is an indicator, you can dip litmus paper or pH paper into the ink solution to see if there is a color change indicating a change in pH. You can also add a few drops of ink to a solution with known acidity or alkalinity to observe any visible changes in color. Additionally, you can perform a titration using the ink solution to determine its pH level.
What is used to test if something is acidic?
A universal indicator or pH paper can be used to test if something is acidic. This test is based on a color change in the indicator or paper when it comes into contact with acidic substances.
What is the indicator and color change for a positive test for glucose?
Benedict solution is the chemical indicator for simple sugars.
The indicator in a test tube change colour orange to yellow what process is it?
This change in color indicates a chemical reaction taking place in the test tube. The specific reaction that caused the color change would depend on the substances present in the test tube and their chemical properties.
When performing a Hemoccult test which color is positive indicator of blood?
In a Hemoccult test, a positive indicator of blood is shown by a blue color change on the test card. This occurs when the sample contains hemoglobin, which reacts with the developer solution. It's important to follow the manufacturer's instructions for accurate interpretation of results.

What is the principle of bromocresol purple in albumin test?
Bromocresol purple is a pH indicator dye that changes color based on the pH of a solution. In an albumin test, bromocresol purple is used to detect the presence of albumin in urine or serum by changing color from yellow to purple in the presence of albumin. This color change occurs because albumin binds to the dye molecule, causing a shift in pH that results in the color change.
What is universal indicator state the purpose for which this indicator is used?
Universal indicator is a mixture of dyes that changes color in response to different pH levels. It is used to determine the approximate pH of a solution by observing the color change of the indicator when added to the solution.
What will happen if a solution of shampoo is added to china rose indicator?
China rose indicator is typically used in chemistry to test for the presence of acids and bases. If a solution of shampoo is added to China rose indicator, the indicator will change color based on the pH of the shampoo. If the shampoo is acidic, the indicator will turn a pink or red color. If the shampoo is basic, the indicator will turn a green or blue color.
What is the indicator used to test for starch hydrolysis?
The indicator used to test for starch hydrolysis is iodine. Iodine reacts with starch to form a dark blue-black color, so if the color change is observed after treating a sample with an amylase (enzyme that breaks down starch), it indicates that starch has been hydrolyzed.
What color does red cabbage indicator change to in alkali?
either a green, dark green or blue colour for i have done the test myself
What does universal indicator test for?
A universal indicator changes color in response to the pH of a liquid. Do determine the pH of the liquid, you need to refer to a color chart that tells you which color indicates which pH.
