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.
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.
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
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.
Sodium bisulfite does not have a fixed freezing point as it is a mixture of sodium metabisulfite and sodium sulfite. The freezing point can vary depending on the composition of the solution. Generally, a solution of sodium bisulfite will freeze at a lower temperature than water due to its composition.
To find the moles of sodium chloride solute in 155 grams of an 85.5% solution, first calculate the mass of sodium chloride present in the solution (mass percent x mass of solution). Then, convert the mass of sodium chloride to moles using its molar mass (58.44 g/mol). This will give you the number of moles of sodium chloride solute in the solution.
To prepare a 0.01N solution of sodium metabisulfite, you would need 2.31 grams of sodium metabisulfite per liter of solution.

Sodium metabisulfite and sodium bisulfite are both chemical compounds used as preservatives and antioxidants in various industries. The main difference between them lies in their chemical structures and properties. Sodium metabisulfite (Na2S2O5) is a white crystalline powder that is commonly used as a food preservative and in the production of wine and beer. It is a stronger antioxidant compared to sodium bisulfite and is more stable in acidic conditions. Sodium metabisulfite is also used in water treatment and as a bleaching agent in the textile industry. On the other hand, sodium bisulfite (NaHSO3) is a white to yellowish crystalline powder that is less stable than sodium metabisulfite. It is commonly used as a food preservative, particularly in the preservation of fruits and vegetables. Sodium bisulfite is also used in the treatment of wastewater and in the production of paper and textiles. In summary, sodium metabisulfite is a stronger antioxidant and more stable in acidic conditions compared to sodium bisulfite. Both compounds have similar applications as preservatives and antioxidants, but their specific properties make them more suitable for different industries and processes.
