Sodium carbonate (NaCO3) is a weak base and sodium chlorite (NaCl3O) is a good oxidizing agent. Many foul odors contain thiol (-SH) groups. Sodium clorite oxidizes the thiols to thioethers (-S-S-), which have no (or little) odor. The reaction occurs more readily at high pH (hence the addition of base).
What else can I help you with?
How can we make a solution of sodium carbonate?
Take water in a beaker. Add sodium carbonate to it and stir till sodium carbonate dissolves. However for scientific or any practical purpose, take a fixed weight of sodium carbonate and dissolve in a definite volume of water and calculate the concentration in terms of molarity or weight per volume etc.
What happens when you add sodium hydrogensulphate to sodium carbonate?
When sodium hydrogen sulfate is added to sodium carbonate, a double displacement reaction occurs. This results in the formation of sodium sulfate and carbonic acid. However, carbonic acid is unstable and breaks down into water and carbon dioxide.
What happens when you add sodium hydrogen carbonate and HCl?
When you add sodium hydrogen carbonate (baking soda) to hydrochloric acid (HCl), a chemical reaction occurs that produces carbon dioxide gas, water, and sodium chloride (salt). The carbon dioxide gas causes bubbling or fizzing, indicating the production of gas. This reaction can be used to demonstrate the neutralization between an acid (HCl) and a base (sodium hydrogen carbonate).
The formula for sodium carbonate is Na2CO3. Figure the molar mass of sodium carbonate to the nearest gram?
To calculate the molar mass of sodium carbonate (Na2CO3), you can add up the atomic masses of each element in the formula: 2(Na) + 1(C) + 3(O). The atomic masses are: Na = 23 g/mol, C = 12 g/mol, O = 16 g/mol. Therefore, the molar mass of sodium carbonate is approximately 106 grams/mol.
Why it is necessary to add sodium carbonate during the preparation of sodium fusion tube?
Sodium carbonate is added during the preparation of a sodium fusion tube to help create a more basic environment that promotes the formation of water-soluble compounds. This facilitates the extraction of certain metals or elements present in a sample through the formation of stable and soluble complexes. Additionally, sodium carbonate helps prevent the formation of unwanted side products during the fusion process.
How Make up a 7.5 percent solution of sodium carbonate in water?
To make a 7.5% solution of sodium carbonate in water, add 7.5 grams of sodium carbonate to 100 mL of water and stir until the sodium carbonate is completely dissolved. This will give you a 7.5% (w/v) solution of sodium carbonate.
What forms when we add sodium carbonate and copper sulphate?
sodium carbonate + copper sulfate ===> copper carbonate (s) + sodium sulfateNa2CO3(aq) + CuSO4(aq) ===> CuCO3(s) + Na2SO4(aq)

Why is it important to add sodium chloridne to water when making homemade ice cream?
If you add calcium carbonate to 100g of water at 25oC, only 0.0014g of it will dissolve. Additional calcium carbonate will not dissolve.

What is the procedure for making and isolating sodium chloride from sodium carbonate?
put the mixture in water and add hydrochloric acid the carbonate becomes decomposed when no further bubbles appear by adding hydrochloric acid then heat the mixture till dryness and get the solid sodium chloride.
What reaction can be performed to tell the difference between sodium carbonate and sodium sulphate?
Add a few drops of a strong acid such as hydrochloric acid to sample of the substance. If it is sodium carbonate then it will bubble carbon dioxide: Na2CO3 + HCl -> NaCl + CO2 (unbalanced) In the other case, it won't.

What is the best way of making zinc carbonate?
One way to make zinc carbonate is by reacting a soluble zinc salt (such as zinc sulfate or zinc chloride) with a carbonate salt (such as sodium carbonate or sodium bicarbonate) in a solution. The zinc carbonate will precipitate out of the solution as a solid, which can then be filtered and dried.
Why do you add sodium carbonate solution for Fmoc ptotection?
to make the solution basic enough so that NH be prepared for Fmoc protection
