$28 NO_{3}^{-} + 3 As_{2} S_{3} + 4 H_{2} O \to 6 AsO_{4}^{3 -} + 28 NO + 9 SO_{4}^{2 -} + 8 H^{+}$

What will be the equivalent mass of As₂S₃ in the above reaction?

Answer:

Solution:

The given equation is –

n-factor of As₂S₃ = $2 \times 2 + 8 \times 3 = 28$ .

Both As and S have been oxidized.

Therefore, Equivalent weight of As₂S₃ = $\frac{M . w . t}{28}$ .
