1 Reactions of metals with acid Wednesday 27th JulyReactions of metals with acid
2 Reaction of metals All acids contain Hydrogen Metal + acid salt + hydrogenThe salt formed depends on the acid usedHNO3 forms Nitrate saltsH2SO4 forms Sulphate saltsHCl forms Chloride salts
3 Reactivity series of metals PotassiumsodiumcalciummagnesiumaluminiumzincIronLead(Hydrogen)coppersilvergoldDecreasing activityEven though hydrogen is not a metal it can be placed in the reactivity series due to its reactivityMetals above hydrogen in the reactivity series will react with acid to make a salt + hydrogen.Metals below hydrogen will not react with acids.
4 Why do metals react with acid? ClHMetal more reactive than HNaCl+H
5 The more reactive the metal, the more vigorous the reaction. The least reactive metals do not react at all.PotassiumsodiumcalciummagnesiumaluminiumzincIronLead(Hydrogen)coppersilvergoldDecreasing activityWhich metal fits the description silver; potassium; ironExplodes in acidBubbles slowly in warm acidDoesn’t react
