Question

Match the salts given in Column I with their method of preparation given in Column II.

Answer 1

A. $Pb(N{O}_3{)}_2$ is a soluble salt. When insoluble salt reacts with acid it give soluble salt and water. This reaction is known as neutralization reaction.

$PbO+2HN{O}_3\to Pb(N{O}_3{)}_2+H_{2}O$

B. $Mg$ to $MgC{l}_2$ is a simple displacement reaction. Active metal displaces $H$ from the acid.

$Mg+2HCl\to MgC{l}_2+H_2$

C.$Fe$ to $FeC{l}_3$ is a combination reaction. $Fe$ reacts with a non-metal to form salt.

$Fe+3C{l}_2\to 2FeC{l}_3$

D. $NaN{O}_3$ from $NaOH$ is a titration reaction. In titration soluble base reacts with acid to form soluble salt and water.

$NaOH+HN{O}_3\to NaN{O}_3+H_{2}O$

E. $ZnC{O}_3$ from $ZnS{O}_4$ is a precipitation raection. Soluble salt reacts with other soluble salt to give a soluble salt and precipitated insoluble salt.

$ZnS{O}_4+(N{H}_4{)}_{2}C{O}_3\to (N{H}_4{)}_{2}S{O}_4+ZnC{O}_3$
