(vi) Calcium nitrate
$C a (N O_{3})_{2}$ $C a (O H)_{2}$ $-$

Following are the reactions of formation of salt from respective acids and bases:

${N H}_{4} O H + H C l \to {N H}_{4} C l + H_{2} O$

$C u {(O H)}_{2} + H_{2} {S O}_{4} \to {C u S O}_{4} + 2 H_{2} O$

$N a O H + H C l \to N a C l + H_{2} O$

$M g {(O H)}_{2} + 2 {H N O}_{3} \to M g {({N O}_{3})}_{2} + 2 H_{2} O$

$2 K O H + H_{2} {S O}_{4} \to K_{2} {S O}_{4} + 2 H_{2} O$

$C a {(O H)}_{2} + 2 {H N O}_{3} \to C a {({N O}_{3})}_{2} + 2 H_{2} O$

Hence, p is $H C l$ .
