How do we prepare NaOH from NaCl?
It is generally prepared by electrolysis of sodium chloride in Castner-kellner cell. A brine solution is electrolyzed using mercury cathode and carbon anode. Sodium metal, discharged at the cathode, combine with mercury to form sodium amalgam. Cl gas is evolved at the cathode.
How do you make cl2 from NaCl?
Chlorine can be manufactured by the electrolysis of a sodium chloride solution (brine), which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2). These two products, as well as chlorine itself, are highly reactive.
What is the reaction between NaCl and H2O?
It’s called the ‘Chlor-alkali process’. Electric current is passed through brine and water to get sodium chloride, chlorine and hydrogen. This type of reaction is also known as Neutralization reaction . Whenever a sacl (NaCl) reacts with water (H2O) acid and base are formed and the reaction is called neutralization.
What is the preparation method of NaCl?
Sodium chloride is obtained by mining the deposits and brine solution is obtained by passing water into the deposits. Hence the salts get dissolved then the solution is pumped out. Evaporation of the sea water is one of the major processes used to obtain salt and is most widely followed in countries like India.
How do you make na2o2 from NaCl?
Preparation of sodium peroxide: Sodium chloride is first converted in sodium by electrolytic reduction. The metals are then heated with an excess of oxygen at about 573K in an atmosphere free from moisture and carbon dioxide to form sodium peroxide.
How is Cl2 formed?
Illustration of the sharing of electrons (dots and crosses) between two chlorine atoms (Cl) to form a molecule of chlorine (Cl2). This is an example of covalent bonding, with the single bond formed by a shared electron pair consisting of an electron from each atom.
What type of reaction is NaOH HCl → H2O and NaCl?
This reaction involve an acid (HCl) reacting with a base (NaOH), producing a salt (NaCl) and water. Therefore it’s a neutralization reaction.

How can you prepare sodium hydroxide name the products formed on cathode and anode write one use of each by product formed in the above reaction?
A brine solution is electrolyzed using mercury cathode and carbon anode. Sodium metal, discharged at the cathode, combine with mercury to form sodium amalgam. Cl gas is evolved at the cathode. The amalgam is treated with water to give sodium hydroxide and hydrogen gas.
How do you remove a NaCl from an aqueous solution?
You can use dialysis membrane to remove NaCl from high molecular weight molecules by using a proper cut-off molecular weight membrane.
What is the balanced equation for NaOH + Cl2?
NaOH + Cl2 = NaCl + NaClO + H2O | Chemical reaction and equation Sodium hydroxide react with chlorine 2NaOH + Cl 2 → NaCl + NaClO + H 2 O [ Check the balance ]
What is the reaction between NaOH and HOCl?
NaOH gives the OH- ion, which attacks on the Cl2 gas which is bubbled through the solution of NaOH. This reaction takes place as follows : Usually the reaction being in basic medium doesn’t stop there – HOCl further reacts with NaOH to give NaOCl (Sodium Hypochlorite) This is the combined Equation.
What is the reaction between NaCl and NaClO3?
It goes from 0 in the chlorine molecules on the left-hand side to -1 (in the NaCl) and +5 (in the NaClO3).This is also a disproportionation reaction. NaClO (sometimes written as NaOCl) is sodium chlorate (I). The old name for this is sodium hypochlorite – and the solution on the right-hand side of the equation is what is normally sold as bleach.
What happens when sodium hydroxide reacts with chlorine?
Sodium hydroxide react with chlorine. 2NaOH + Cl2 → NaCl + NaClO + H2O. Sodium hydroxide react with chlorine to produce sodium chloride, sodium hypochlorite and water. This reaction takes place in a cold, diluted solution.
