Question

A metal salt mx when exposed to light splits up to form metal m and a gas x2 . metal m is used in making ornaments whereas gas x2 is used in making bleaching powder.the salt mx is itself used in black and white photography.a.what do you think metal m is?b.what could be gas x2?c.name the metal salt mx.d.what type of reaction takes place when salt mx is exposed to light? write the equation of the reaction.

Answer 1

the metal is silver Ag
the gas is chlorine Cl
the metal salt is silver chloride AgCl
when this salt is exposed to light decomposition reaction takes place.
eq
AgCl. - Ag + Cl2

Answer 2

the metal is silver Ag

the gas is chlorine Cl

the metal salt is silver chloride AgCl

when this salt is exposed to light decomposition reaction takes place.

eq

AgCl. - Ag + Cl2
