Question

23 gram of sodium when heated in current of dry chlorine produces 58.5gm of sodium chloride then what will be the equivalent weight of sodium​

Answer 1

Molar mass of sodium = 23g

Molar mass of NaCl= 23 + 35.5 = 58.5g

Equivalent weight = $\frac{Molar\:\:\: mass\:\:\: of \:\:\:element}{no.\:\:\:elctrons\:\:\:lost}$

No. of electrons lost = Na  → Na⁺ + e⁻

So, one electron is lost

equivalent weight of Na = $\frac{23}{1}$ = 23 g
