Question

Eauation of reaction of shulphurdioxide with aqueos sodium hidroxide

Answer 1

odium hydroxide Formula

Sodium hydroxide is one of the most common inorganic bases or alkalis. It is also called caustic soda or lye.

Formula and structure: The chemical formula of sodium hydroxide is NaOH, and its molar mass is 40.01 g/mol. It is the alkali salt of sodium, and its structure is shown below:

It is an ionic compound consisting of sodium cation (Na+) and hydroxide (OH-) anion.

Preparation:

Sodium hydroxide is industrially produced using the electrolytic chloralkali process, in which electrolysis of aqueous sodium chloride solution gives chlorine gas and sodium hydroxide. NaOH is obtained as a 50% solution in water, and then dried to give solid sodium hydroxide flakes or pellets.

2 NaCl + 2 H2O → 2 NaOH + Cl2 + H2
