All the following will liberate a gas when reacted with dilute hydrochloric acid except ____________
A. Sodium trioxosulphate (IV) salt B. Sodium trioxocarbonate (IV) salt C. Sodium sulphide D. Sodium trioxonitrate \((V)\)
Correct Answer: D
Explanation
Here, we consider the equation of reaction of the given compounds, i.e. \(Na _{2} SO _{3(s)}+2 HCl _{( aq )} \rightarrow 2 NaCl _{( aq )}+ SO _{2( g )}+ H _{2} O _{( s }\) \(Na _{2} CO _{3(s)}+2 HCl _{( sq )} \rightarrow 2 NaCl _{(2 q)}+ CO _{2(s)}+ H _{2} O _{( l )}\) \(Na _{2} S _{( s )}+2 HCl _{( aq )} \rightarrow 2 NaCl _{( aq )}+ H _{2} S _{( g )}\) \(NaNO _{3(5)}+2 HCl _{( laq )} \rightarrow 2 NaCl _{( aq )}+ HNO _{3( aq )}\) Option \(D\) does not liberate a gas hence, it is wrong.
