A metal X forms a water-soluble seat `XNO_(3)` When an aqueous solution of `XNO_(3)` is added to the common salt solution, then a white precipitate of compound Y is formed along with sodium nitrate solution. Metal X is said to be the best conductor of electricity and it does not evolve hydrogen when put in dilute hydrochloric acid.
(a) What is metal X ?
(b) What is salt `XNO_(3)` ?
(c ) Name the compound Y. (d) Write the chemical equation of the reaction which takes place on reaction `XNO_(3)` 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?

Answer

(a) Silver (Ag) (b) Silver nitrate `(AgNO_(3))` (c) Silver chloride `(AgCl)` (d)` AgNO_(3)` (aq) + NaCl (aq) `to AgCl(s) + NaNO_(3) (aq)` (e) Double displacement reaction
