Which gas is produced, when dilute hydrochloric acid is added to a reactive metal?Write the chemical equation , when iron reacts with dilute H_2SO_4?

Answer»

Solution :Hydrogen gas is PRODUCED, when a metal reacts with dilute hydrochloric acid
`M(s)_(Met al)+2HCL(aq)_(Hydrochloric acid (Dilute))to MCl_2(s)_(Met al Chloride)+H_2(g)_(HYDROG en)`
Chemical equation for the reaction of iron with dilute `H_2SO_4` is
`Fe(s)_(Met al)+ H_2So_4(aq)_(Dilute su lphuric acid ) to FeSo_4(aq)_(Iron II su lpha te)+H_2(g)_(Hydrog en)`
