In pool maintenance we use a bottle labeled R-004 to test the ph.
In chemistry labs, you might use phenolphthalein solution, litmus paper, or other pH test paper, depending on the situation.

A substance used to detect or measure another substance or to convert a substance into another?
a reagent
What is the purpose of m9 paper?
Chemical Agent Detector Paper, M9 is the most widely used method of detecting liquid chemical warfare agents, such as nerve or blister agents. M9 Paper reacts to chemical agents by turning a red or reddish brown color. It will not detect vapor.
What substance used to detect the presence of carbon dioxide?
Test for Carbon Dioxide: Bubble unknown gas in lime water. Limewater should go milky if Carbon dioxide is present. Test for water: Add anhydrous copper sulphate crystals (white in colour) to unknown solution. If solution goes a brilliant light blue colour, water is present as the hydrous copper sulphate crystals were formed. Did this help?
What type of substance is litmus?
Litmus is used to indicate the either the chemical to be used is acid or a base. so the substances that change colour like litmus are called INDICATORS. Methyl orange and phenolphthalein is also an indicator.
What does electroscope measure?
An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.[1] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope that are still used in physics education to demonstrate the principles of electrostatics. A type of electroscope is also used in the quartz fiber radiation dosimeter.Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines. Electroscopes generally give only a rough, qualitative indication of the magnitude of the charge; an instrument that measures charge quantitatively is called an electrometer.Source : Wikipedia
Can nucleic acids be detected by the ELISA format?
No, ELISA would not be able to detect the presence of nucleic acids. As ELISA uses a antibodies to detect the presence of a antigen. Hence as the nucleic acid is within the cell (nucleus), the antibody used does not attach themselves to the nucleic acid but to the antigen.
Why can phosphorus-32 be used to detect the presence of nucleic acids but not amino acids?
amino acids only contain carbon,hydrogen,oxygen and nitrogen. they do not contain phosphorus and cannot be incorporated. the ion phosphoric acid is found in nucleic acid.
Sudan III is used to detect the presence of what macromolecules?
Sudan III is used to detect the presence of lipids.
What material is used to show the presence of a substance?
An indicator shows the presence of another substance.
A substance used to detect or measure another substance or to convert a substance into another?
a reagent
Which substance is used in LPG to detect leakage?
Ethanethiol is commonly used as an odorant in LPG to detect leaks.
What is used to detect the presence of an acid or alkali?
pH strips
A pap smear is used to detect the presence of abnormal cells in the?
A pap smear is used to detect the presence of abnormal cells in the cervix, most often. Vaginal and anal pap smears are also used.
What test can be used to detect substance of emulsion?
Penis
What are immunoassay tests?
chemical tests used to detect or quantify a specific substance, the analyte, in a blood or body fluid sample, using an immunological reaction
What is M8?
It is used to detect and identify the presence of liquid chemical agents.
What chemical substance you is used to detect the presences of starch?
An iodine solution is used.
