Question

An excess of Na₂S₂O₃ react with aqueous CuSO₄ to give

A

CuS₂O₃

B

Cu₂S₂O₃

C

Na₂ [Cu(S₂O₃)₂]

D

Na₄[Cu₆(S₂O₃)₅]

Answer

Na₄ $Cu<sub>6</sub>(S<sub>2</sub>O<sub>3</sub>)<sub>5</sub>$

Explanation

Solution

CuSO₄ + Na₂S₂O₃ ¾® CuS₂O₃ + Na₂SO₄

2CuS₂O₃ + Na₂S₂O₃ ¾® Cu₂S₂O₃ + Na₂SO₄O₆

3Cu₂S₂O₃ + 2Na₂SO₃ ¾® Na₄[Cu₆(S₂O₃)₅]
