reactivity of metals Flashcards
reactions of metals with acids metal and non-metal oxides displacement reactions
when metals and acids react what must the metal be above of in the reactivity series
hydrogen
what do use to test for hydrogen
a lit splint
when dilute acid is put in with gold silver and copper what will happen when there is a lit splint put on top of the test tube
no reaction
what happens when hydrogen lead iron zinc or carbon is put in a test tube with a dilute acid and a lit splint is placed above
moderate reaction and steady bubbling
what happens when pottassium calcium and sodium are put in a test tube with a dilute acid and a lit splint is placed above9
violent reaction and fast bubbling
what is the word equation formation for metal oxides
metal + oxygen —> metal oxixde
what does the ph need to be higher then in metal oxides
higher than 7 (alkaline)
will metal oxides react with acids
yea
what is the word equation for when metal oxides react with acids
acid + metal oxides –> salt + water
what is the word equation to form no-metal oxides
non-metal + oxygen –> salt + water
what is the ph for non-metal oxides
lower than 7 (acidic)
what is the word equation for when non-metals react with alkalis
alkali + non-metal oxides –> salt + water
what is a displacement reaction
when a more reactive element displaces a less reactive element from its compound
is neutralisation a displacement reaction
yes
what happens during neutralisation displacement reaction
the hydrogen in the acid is displaced by the metal from the alkali
what happens when you add magnesium to zinc sulfate solution
more reactive metal will take the place of the less reactive metal.
there will be a zinc coating and magnesium sulfate solution
what happens when you add copper to zinc sulfate solution
because copper is a less reactive metal so there will be no reaction
