Bicarbonate salt of metal + dilute acid → Another salt of metal + carbon dioxide + water
Answer
1. $NaHCO _{3( ss }+ HCl _{( aq )} \longrightarrow NaCl _{( aq )}+ CO _{2( g )}+ H _2 O _{( l )}$ 2. $KHCO _{3( s )}+ HNO _{3( aq )} \longrightarrow KNO _{3( aq )}+ CO _{2( g )}+ H _2 O _{( ) )}$ 3. $NaHCO _{3( s )}+ CH _3 COOH _{( aq )} \longrightarrow CH _3 COONa _{( aq )}+ CO _{2( gg )}+ H _2 O _{( f }$
Carbonate salt of metal + dilute acid → Another salt of metal + Carbon dioxide + water
Answer
$\begin{array}{lll} Na _2 CO _{3( ss }+ H _2 SO _{4( aq )} & \longrightarrow & Na _2 SO _{4( aq )}+ CO _{2( g )}+ H _2 O _{(l)} \\ CaCO _{3( s )}+2 HNO _{3( aq )} & \longrightarrow & Ca \left( NO _3\right)_{2( aq )}+ CO _{2( g )}+ H _2 O _{(l)} \\ K _2 CO _{3( s )}+ H _2 SO _{4( aq )} & \longrightarrow & K _2 SO _{4( aq )}+ CO _{2( g )}+ H _2 O _{(l)}\end{array}$
$\begin{aligned} & CO _{2( g )}+2 NaOH _{\text {(aq) }} \longrightarrow Na _2 CO _{3( aq )}+ H _2 O _{(0)} \\ & CO _{2( l )}+2 KOH _{\text {(aq) }} \longrightarrow K _2 CO _{3( aq )}+ H _2 O _{( l )} \\ & SO _{3( gg )}+2 NaOH _{( aq )} \longrightarrow Na _2 SO _{4( aq )}+ H _2 O _{(l)}\end{aligned}$
$\begin{aligned} & CaO _{( s )}+2 HCl _{(\text {(aq })} \longrightarrow \underline{ CaCl _{2 \text { (aq) }}}+ H _2 O _{(j)} \\ & MgO _{\text {(s) }}+2 HCl _{\text {(aq) }} \longrightarrow MgCl _{2( aq )}+ H _2 O _{\text {(n) }} \\ & ZnO _{( s )}+2 HCl _{( aq )} \longrightarrow ZnCl _{2( aq )}+ H _2 O _{(j} \\ & Al _2 O _{3( s )}+6 HF _{(t)} \longrightarrow 2 AlF _{3( aq )}+3 H _2 O _{(t)} \\ & Fe _2 O _{3( s )}+6 HCl _{( qq )} \longrightarrow 2 FeCl _{3( aq )}+3 H _2 O _{( p )} \\ & \end{aligned}$
$\begin{array}{ll} Mg _{( s )}+2 HCl _{( aq )} & \longrightarrow MgCl _{( aq )}+ H _{2( g )} \\ Zn _{( s )}+ H _2 SO _{4( aq )} & ZnSO _{4( aq )}+ H _{2( g )} \\ Cu _{( s )}+2 HNO _{3( aq )} & \longrightarrow Cu \left( NO _3\right)_{2( aq )}+ H _{2( g )}\end{array}$
