Question

A metal X forms a water soluble salt XNO3. When an aqueous solution of XNO3 is added to common salt solution, then a white precipitate of compound Y is formed alongwith sodium nitrate solution. Metal X is said to be the best conductor of electricity and it does not evolve hydrogen when put in dilute hydrohloric acid.
(a) What is metal X?
(b) What is salt XNO3?
(c) Name the compound Y.
(d) Write the chemical equation of the reaction which takes place on reacting XNO3 solution and common salt solution giving the physical states of all the reactants and products. 
(e) What type of chemical reaction is illustrated by the above equation?

Solution

(a) Metal X is silver.

(b) Salt XNO3 is AgNO3.

(c) The compound Y is AgCl.

(d) AgNO3 (aq) + NaCl (aq) → NaNO3 (aq) + AgCl (s)

(e) The above chemical reaction is a double displacement reaction as well as a precipitation reaction.

  Is there an error in this question or solution?
