When a strip of red-brown metal X is placed in a colourless salt solution YNO3 then metal Y is set free and a blue coloured salt solution X(NO3)2 is formed. The liberated metal Y forms a shining white deposit on the strip of metal X.
(a) What do you think metal X is?
(b) Name the salt YNO3.
(c) What could be metal Y?
(d) Name the salt X(NO3)2
(e) What type of reaction takes place between metal X and salt solution YNO3?

Copper is the metal X which is a red brown strip
Silver nitrate is the salt YNO3 which is a colourless salt
Silver is the metal formed Y upon reaction of copper and silver nitrate solution thus it forms a shining white deposit on the strip metal X
Copper nitrate is X(NO3)2 the salt formed which is blue coloured as copper is present in it
Displacement reaction will be the type of reaction taking place here Cu(s) + 2AgNO3(aq) &rarr; Cu(NO3)2(aq) + 2Ag(s)
