Question

Write balanced chemical equations.

Sodium thlosulphate is reacted with dilute hydrochloric acid.

• A. $2{Na}_2{S}_2{O}_3+HCl\to 2NaCl+H_{2}O+{SO}_2+S$
• B. ${Na}_2{S}_2{O}_3+2HCl\to NaCl+H_{2}O+{SO}_2+S$
• C. ${Na}_2{S}_2{O}_3+2HCl\to 2NaCl+H_{2}O+{SO}_2+S$
• D. $2{Na}_2{S}_2{O}_3+HCl\to NaCl+H_{2}O+2{SO}_2+S$

Answer 1

The correct option is C ${Na}_2{S}_2{O}_3+2HCl\to 2NaCl+H_{2}O+{SO}_2+S$

$N{a}_2{S}_2{O}_3+2HCl⟶2NaCl+H_{2}O+S{O}_2+S$
