What is the purpose of using a glowing splint in heating lead ii nitrate in a test tube?
The purpose of using a glowing splint when heating lead(II) nitrate in a test tube is to test for the presence of oxygen gas, which is released during the decomposition of lead(II) nitrate. When the compound is heated, it breaks down into lead(II) oxide, nitrogen dioxide, and oxygen. A glowing splint will reignite in the presence of oxygen, indicating that the gas is present. This serves as a simple demonstration of the production of oxygen from the chemical reaction.
Does bacillus subtilis have a positive reaction for ONPG Test?
yes it have positive reaction for ONPG test
What is the reaction in Lieberman's burchard test for cholesterol?
In Lieberman's burchard test for cholesterol, the reaction involves the addition of acetic anhydride and concentrated sulfuric acid to a solution containing cholesterol. This results in a color change from red to green or blue-green, indicating the presence of cholesterol.
What is the purpose of hydrolysis test?
The purpose of a hydrolysis test is to determine an organism's ability to break down certain compounds such as starch or gelatin using specific enzymes. This test is commonly used in microbiology to differentiate between different species of bacteria based on their enzymatic capabilities.
What is the equation for the reaction of modified furter-meyer test?
The reaction for the modified Fehling's test involves the oxidation of an aldehyde to a carboxylic acid in the presence of copper(II) ions. This reaction results in the formation of a brick-red precipitate of copper(I) oxide, which indicates a positive test for the presence of an aldehyde group.
What is the purpose of using a model to test a hypothesis?

What happens when acid react with compounds made of carbonate?
When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!
What is the purpose of skin test?
The purpose of a skin test is to assess an individual's immune response to specific allergens, pathogens, or substances. It helps diagnose allergies, infections, or autoimmune conditions by observing the skin's reaction after exposure to a small amount of the test substance. Results can guide treatment decisions and help individuals manage their health effectively.
Purpose of the test in education?

What is the aim of using HCL in seliwanoffs test?
In Seliwanoff's test, the aim of using concentrated hydrochloric acid (HCL) is to provide a mildly acidic environment that helps to catalyze the reaction between the sugar being tested and the reagent (resorcinol). This reaction results in the formation of a colored compound that indicates the presence of ketoses, distinguishing them from aldoses.
