Do spa chemicals go bad?
Yes, spa chemicals can go bad over time due to exposure to air, moisture, and light. This can lead to chemical degradation and a loss of effectiveness in maintaining water quality in the spa. It's important to store spa chemicals in a cool, dry place and check for expiration dates before use.
What reagents break a double bond?
Reagents that break a double bond include hydrogenation reagents (such as H2/Pd or H2/Ni), halogenation reagents (such as Br2 or Cl2), and ozonolysis reagents (such as O3/Zn, and H2O). These reagents can break the double bond by either adding atoms across it or cleaving it into two separate fragments.
What are the chemicals used in forensic science?
Chemicals commonly used in forensic science include luminol for detecting blood traces, ninhydrin for detecting fingerprints, and hydrogen peroxide for detecting blood stains. Other chemicals used include acids for DNA extraction and preservation, as well as various reagents for analyzing drugs and toxic substances.
Difference between laboratory and analytical reagent?
Analytical Reagents Are Useful In Sophisticated Analytical Instruments And Research Work Where High Purity Is Essential While Lab Reagents Are Useful To Carry Out Lab Analysis. ------ There used to be four grades of chemical: food grade, technical grade, lab grade and analytical grade. Food grade was safe and pure for use in foods, technical was for manufacturing nonfood items, lab grade was for lab research and analytical grade was as pure as they could possibly make. Not all chemicals could achieve all four grades; there was no food-grade arsenic or strontium-90 for reasons obvious. And some chemicals are the same in all four grades - borax, a mild base called sodium metaborate, is as pure in the "20 Mule Team" variety at the store as it is in reagent grade. Now there are dozens of grades. Google grades of reagents and the first hit is a very large page listing them all.
Can water go bad and become unsafe to drink?
Yes, water can go bad and become unsafe to drink if it is contaminated with harmful bacteria, viruses, or chemicals. It is important to ensure that water is properly treated and stored to prevent it from becoming unsafe to drink.
When two chemicals react when they are mixed the chemicals are called?
The chemicals which are involved in a reaction are called Reagents or Reactants
What r is the word for the chemicals we start with a reaction?
Reagents Reactants
How many reagents are there in stoichiometry?
Since a "reagent" is synonymous with "chemical", there are as many reagents as there are chemicals - pretty much a near-infinite list.
What is the use of polyethylene bottle?
To contain foods (liquids, granulated, powdered), chemical reagents, other chemicals.
What makes a sims card go bad?
The same things that make other electronics go bad: water, chemicals, and extreme temperatures.
What is the meaning of diagnostic or laboratory reagents on a backing?
Diagnostic or laboratory reagents on a backing refer to chemicals or substances that are applied or housed on a solid material for ease of handling and testing purposes. The backing provides stability and support for the reagents during diagnostic procedures, ensuring accurate and reliable results.
Do spa chemicals go bad?
Yes, spa chemicals can go bad over time due to exposure to air, moisture, and light. This can lead to chemical degradation and a loss of effectiveness in maintaining water quality in the spa. It's important to store spa chemicals in a cool, dry place and check for expiration dates before use.
What is the meaning of romil?
ROMIL is a producer of high purity chemicals, solvents, acids and reagents for both scientific and industrial applications.
Uses of reagent bottle?
Reagent bottles are commonly used in laboratories to store and dispense chemicals, solvents, and reagents. They help to ensure the safe handling and storage of these substances, as well as enable accurate measurements during experiments. Reagent bottles are also used for the preparation of solutions, mixing of reagents, and as a container for samples.
How do you prepare reagents used in the lab?
To prepare reagents used in the lab, you typically follow a protocol or recipe that specifies the amount of each chemical needed. This involves measuring out the chemicals accurately, dissolving them in the appropriate solvent, and adjusting the pH or concentration if required. It is important to label the reagents correctly and store them properly to maintain their stability and integrity.
What has the author Henri Rousset written?

What happens if you mix good chemicals with bad chemicals?
you die
