Question

Write the reaction of


a) Oxidation of glucose

b) Preparation of sodium hydrogen carbonate

c) Preparation of sodium hydroxide​

Answer 1

Answer:

a)Glucose reacts with molecular oxygen to produce carbon dioxide and water. The carbon atoms in glucose are oxidized. That is, they lose electron and go to a higher oxidation state. ... Now consider the reduction of molecular oxygen (0 oxidation state) to water (-II) oxidiation state.

b) Preparation: Sodium hydrogen carbonate is also prepared on large scales by the Solvay process, in which sodium chloride reacts with ammonia, carbon dioxide and water to give NaHCO3 along with ammonium chloride salt (NH4Cl). ... Its melting point is 50 °C, and it is highly water soluble.

c). Chemical equation : 2NaCl + 2H2O ---------------- 2NaOH + Cl2 + H2. The process is chloro-alkali process. Chloro for chlorine and alkali for sodium hydroxide.In this process hydrogen gas is evolved at cathode and chlorine gas is evolved at anode.
