What compound is Na2S2O3?
Antimony sulfide; sodium oxide; carbonic acid.
What is the difference between normal reaction and abnormal reaction?
Normal reaction happens when the reaction is normal. Abnormal reaction happens when the reaction is abnormal.
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
endothermic reaction
What chemical reaction that can proceed forward or backward is a?
You think probable to a reversible reaction.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
What will happen when chloroform and iodin mixed?
There is no reaction. But I2 melt in CHCl3.
How can you prevent oxidation of sodium metabisulfite in solution Is pH an important factor in controlling oxidation of metabisulfite will glycerol addition stop oxidation of metabisulfite?
sodium metabisulfite oxidizes best in an alkaline (basic solution). In low pH (2-3) the reaction occurs very slowly or not at all..
What is exact reaction between sodium metabisulfite and bromine?
2NaHSO3 + Br2 + H2O = NaBr + NaOBr + SO2 + H3O+ I am not happy with this answer - you have a positive charge appearing from nowhere. Also NaHSO3 is sodium bisulfite the questioner asked for sodium metabisulfite which is Na2S2O5 . However, sodium metabisulfite in the presence of water does convert to sodium bisulfite Na2S2O5 + H2O = 2NaHSO3 2NaHSO3 + Br2 + H2O = 2NaBr + H2SO4 + H2SO3
What is the fullform of chemistry?
c-carban h-hydrogen e-easter m-methane i-iodin s-sulpher t-titenium r-reaction y-yield
Why sulphuric acids is not used in the reaction of alcohols with potassium iodide?
As sulphurib acid an oxidising agent therefore it oxidis iodin anions to iodioe aiatomic gas so it leads to the failure at product
What is metabisulfate?
Potassium metabisulfite, K2S2O5, also known as potassium pyrosulfite, is a white crystalline powder with a pungent sulfur odour. The main use for the chemical is as an antioxidant or chemical sterilant. It is a disulfite and is chemically very similar to sodium metabisulfite, with which it is sometimes used interchangeably. Potassium metabisulfite is generally preferred out of the two as it does not contribute sodium to the diet.
On peeled potatoes what anti browning agent can be used?
sodium metabisulfite
Why do sodium metabisulfite and garlic extract have food preservative antimicrobial anti-browning properties Please answer urgently?
You can research this from the links below (While Sodium Metabisulfite has anti browning properties I am not sure that garlic does!)

Is sodium metabisulphite a fungicide?
sodium metabisulfite known to be fungicidal when used alone at high concentrations. sodium metabisulfite has potential undesirable side-effects:1) sodium metabisulfite emits sulfur dioxide at acidic pHs creating a potentially toxic atmosphere for humans, they can contribute to acid rain development.2) Residues of sodium sulfite can remain on treated plants. Many people are allergic to sodium sulfite in foods so metabisulfite-containing fungicides should not be applied immediately before harvest.
How do you decompose potassium metabisulfite and create solid potassium oxide?
Heat it to 190 C.
What compound is Na2S2O3?
Antimony sulfide; sodium oxide; carbonic acid.
