The reaction between metabisulfite and iodine forms iodide ions and bisulfite ions. The metabisulfite reduces the iodine to iodide ions, while itself is oxidized to bisulfite ions. This reaction is commonly used as a titration method to determine the concentration of iodine in a solution.
What else can I help you with?
What compound is Na2S2O3?
Antimony sulfide; sodium oxide; carbonic acid.
What is metabisulfite powder?
Metabisulfite powder is a chemical compound commonly used as a food preservative and as a sanitizer in brewing and winemaking. It helps to prevent oxidation and spoilage in food and beverages by inhibiting the growth of bacteria and yeast. Additionally, it is used in various industries for its antioxidant properties.
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.
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?
You can prevent oxidation of sodium metabisulfite in solution by storing it in a cool, dark place with minimal exposure to air. pH is an important factor in controlling oxidation, as lower pH levels can help stabilize metabisulfite and reduce oxidation. Adding glycerol may not necessarily stop oxidation of metabisulfite, but it could potentially help to slow down the process by acting as a stabilizer.
How will combine H2O plus Na2SO5?
Combining H2O (water) and Na2SO5 (sodium metabisulfite) will result in a reaction where the sodium metabisulfite will dissolve in water to form sodium ions (Na+) and bisulfite ions (HSO3-). This reaction is reversible, and the extent of dissociation will depend on the concentration and conditions.
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
How many grams of sodium metabisulphite is needed to make 0.01N solution?
To prepare a 0.01N solution of sodium metabisulfite, you would need 2.31 grams of sodium metabisulfite per liter of solution.
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!)

How many grams of sodium metabisulfite is needed to make 10 percent solution?
Put 100 grams in a beaker and and around 500 mls of water until it dissolves, then top up the beaker to a liter. That is your 10% solution. The percentage solution is a ratio of the weight of the compound to the weight of the final solution.
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.
