How lớn Balance the cold dilute Na
OH and Cl2 reaction

We know this reaction is a disproportionation reaction. When we see the products, it's clear that Cl2 is oxidized to lớn OCl- and reduced lớn Cl-. Oxidation numbers of chlorine in OCl- ion is +1 and Cl- ion is -1.Now kiểm tra the differences of each oxidation numbers in oxidation & reduction. It is one in both. Then exchange the differences.Then balance other elements. Kiểm tra number of Sodium atoms in both sides. There are two Sodium atoms in the right side. So we make two number of Na
OH.Then check the balance of number of hydrogen atoms. Left side has two hydrogen atoms so far now. Then only one H2O molecule in the right side is enough to lớn balance the number of hydrogen atoms in the equation.

This type of redox reaction balancing example is reaction of chlorine gas with ammonia.

Mechanism of Cl2 gas & dilute cold Na
OH reaction

When chlorine gas dissolve in water and reacts with water, it produce hypochlorous acid (HOCl) & hydrochloric acid (HCl). You know acids react with bases và produce a salt and water as products. So, when Na

3Cl2 + 6MOH → 5MCl + MCl
O3 + 3H2O

What will happen, when Cl2 gas is sent to lớn the water?

Cl2 hydrolysis in the water. HCl và HOCl are given as products. HCl is a strong acid và HOCl is a weak acid. HOCl is a very good disinfectant và more efficient than bleaching powder.

Can I use this chlorine & Na
OH reaction to lớn neutralize Cl2 gas?

Yes. You can use Na
OH & this is very efficient way to vì the neutralization. But you have khổng lồ consider about the cost of this neutralization method because Na
OH is so expensive.

What is chlorinated water or chlorination of water?

The process of adding chlorine or chlorine compounds such as sodium hypochlorite (Na
OCl) to lớn water. This is done in swimming pools. This is done to kill certain bacteria và other microbes in tap water as chlorine is toxic lớn those microbes. That's why we feel smell of chlorine gas in the swimming pools.

Chlorine reacts with hot và concentrated Na
OH, But why products are different?

When temperature is high, the ability lớn oxidation is high. Therefore produced Na
OCl is oxidized khổng lồ Na
Cl
O3 from +1 to +5 (oxidation umber of chlorine).

How this reaction is different from sodium hydroxide và HCl reaction?

Na
OH & HCl reacts as base và acid respectively và produce salt (Na
Cl) and water as products. That reaction is not a redox reaction.

disproportionation reaction of water with sodium hydroxide

There is no disproportionation reaction oof water và sodium hydroxide. Only sodium hydroxide dissolve very well in water and dissociate khổng lồ sodium ion and hydroxyl ions completely.

OCl- ion oxidation state?

We know electronegativity of oxygen is higher than chlorine. So negative charge should be on oxygen atom whole chlorine atom is oxidized due lớn higher electronegativity of oxygen. There is a single bond between oxygen and chlorine. Therefore oxidation number of chlorine is +1.

What will be the p
H value after cold dilute Na
OH reacts with chlorine gas if reactants are completely finished?

We know Na
OH is a strong base. So it shows higher p
H value which is greater than 7 at 250C.

How p
H is calculated for a strong base?

When all Na
OH reacts with all chlorine, there is no remaining Na
OH and Cl2. Produced Na
Cl và Na
OCl are in the solution and we should consider, whether their ability khổng lồ hydrolysis of water to lớn make water acidic or basic.

how does sodium hydroxide neutralize chlorine?

Use aqueous sodium hydroxide solution lớn neutralize chlorine gas. But commonly, spraying a solution of baking soda in water into the air or urea solution will be used. Cost of Na
OH is very high.

Chlorine gas reacts with iron & produce ferric chloride. So we cannot use iron as the reactant container equipment.

Also, caustic soda slowly reacts with glass and form sodium silicate. So glass container is also not suitable for the reaction equipment.

Stability of Na
Cl

Sodium ion và chloride ion are stable in the water và do not involve in hydrolysis of water. So Na
Cl is a neutral salt.

Stability of Na
OCl in water

Hypochlorite ion is not stable in water và involve in hydrolysis of water to lớn produce HOCl & OH- ion. So aqueous solution will basic due to lớn release of hydroxyl ion. Due lớn formation of OH- ions, aqueous solution gets basic và show p
H values of greater than 7. But this solution is not basic as an aqueous Na
OH solution.

Can I vày the experiment of Na
OH, Cl2 reaction in the laboratory?

Yes. You can. You can prepare cold Na
OH solution by using ice crystals or cold water. But, you will be find difficult lớn find chlorine gas in the laboratory. Then, you can try to make chlorine gas yourself. Mix dilute HCl solution and potassium permanganate solution. That will give Cl2 gas. Feed produced Cl2 gas safely through tubes to the Na
OH solution.

reaction of chlorine with sodium hydroxide acid or base?

Reaction of chlorine with sodium hydroxide can be considered as an acid-base reaction. How vày I say that?

First, chlorine dissolve in water & produce hydrochloric acid (HCl) and hypochlorous acid (HOCl). These two acids react with Na
OH separately lớn give Na
Cl và Na
OCl respectively.
