Question

Find the N factor of

Na2CO3·10H20

Answer 1

Answer:

n-factor of Na₂CO₃ is 2

n-factor is defined as the number of moles of electrons exchanged

(lost or gained) by a mole of the salt.

Other name for n-factor is valence electrons

Here,

In this compound Na₂CO₃

Their individual exits as $\rm Na^+ \;and \;CO_3^2-$

As we can see clearly,

Two valence electrons are required for $\rm CO_3^2-$ to attain complete configuration.(Stable configuration)

Similarly

$\rm Na^+$ readily donates a electron to attain octet configuration as Neon(Stable  configuration)

So 2 $\rm Na^+$ combine with $\rm CO_3^2-$ to form a compound (Sodium carbonate)

As 2 e⁻ are lost and gained in $\rm Na^+ \;and\;CO_3^2-$ respectively.

The n-factor of Na₂CO₃ is 2
