How do you make sodium hypochlorite from sodium hydroxide?

In the process, sodium hypochlorite (NaClO) and sodium chloride (NaCl) are formed when chlorine is passed into cold dilute sodium hydroxide solution. The chlorine is prepared industrially by electrolysis with minimal separation between the anode and the cathode.

Which product will form when hot and concentrated sodium hydroxide reacts with cl2 a NaClO B naclo2 C NaClO3 D naclo4?

The correct answer is option 2 i.e. NaClO3. NaClO3 or Sodium chlorate appears as an odorless pale yellow to white crystalline solid.

How do you make sodium hypochlorite from nacl?

Sodium hypochlorite can be produced in two ways: – By dissolving salt in softened water, which results in a concentrated brine solution. The solution is electrolyzed and forms a sodium hypochlorite solution in water. This solution contains 150 g active chlorine (Cl2) per liter.

What is action of chlorine on cold and dilute NaOH?

Chlorine reacts with cold and dilute sodium hydroxide to produce a mixture of chloride and hypochlorite.

What is the action of Cl2 on cold and dilute NaOH?

How does Cl2 reacts with cold and dilute NaOH?

(a) With cold dilute solution of sodium hydroxide , Cl2 undergoes disproportionation to give a mixture of sodium chloride, NaCl and sodium hypochlorite (NaOCl). Cl2+H2IO→HCl+HOClyellow→2HClcolourless+[O].

What are the product obtained when Cl2 reacts with hot and concentrated NaOH?

When chlorine gas is reacted with hot and concentrated sodium hydroxide solution to give the product of sodium chloride and hypochlorite.

How is sodium hypochlorite formed?

Sodium hypochlorite (NaOCl) is a solution made from reacting chlorine with a sodium hydroxide solution. These two reactants are the major co-products from most chlor-alkali cells. Sodium hypochlorite, commonly referred to as bleach, has a variety of uses and is an excellent disinfectant/antimicrobial agent.
