Question

complete the reacn. and find N- factor
Cl2 + NaOH =
[cold n dilute]

Answer 1

Cl2+2NaOH--->NaCl+H20+NaOCl and not Cl2+NaOH--->NaOCl+HCl?
for balancing the equation 2NaOH

Answer 2

Answer:

Cl2 + NaOH = NaCl + NaClO3 + H2O

N factor = 5

Explanation:

The number of moles in the reactant is 1. So,

Equivalent mass=molar mass of chlorine x 1 / n factor

Molar mass of chlorine is 70 g / mol

Implies,

eq. mass = 70 x 1 / 1=70

Therefore, the equivalent mass = 70 g / equivalent

When chlorine reacts with a cold solution of sodium hydroxide, sodium chloride, sodium chlorate, and water are produced. The following is a balanced chemical reaction:

3Cl2+5NaOH→5NaCl+NaClO3+3H2O

So the number of electrons changes by 5 for both products. The n-factor is hence 5.
