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 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.
What type of chemical reaction is illustrated by the above equation?

Accepted Answer

Silver (Ag) will be metal which conducts electricity and does not evolve hydrogen when put in dilute hydrochloric acid
Silver nitrate (AgNO3) is XNO3 which is reacts with NaCl (common salt) to give white precipitate


Silver chloride (AgCl) is the compound Y formed which is the white precipitate formed from the reaction of silver nitrate and sodium chloride.
AgNO3(aq) + NaCl (aq)&rarr; AgCl (s) + NaNO3 (aq)
Double displacement reaction where two compounds react and the positive ions and negative ions of the two reactants switch places forming new compounds.
