chapter 5 Flashcards
what is the general equation for using metal and acid to make salts
metal + acid —-> salt + hydrogen
when are citric acids found
in fruits like oranges and lemons
how are carbonic acids formed
by reacting carbon dioxide with water
hydrochloric formula
HCI
why can’t some metals react with acids to make a salt
because they are too unreactive to displace the hydrogen from an acid
what is the general equation for making salts with metal oxides
metal oxide + acid —-> salt + water
what is the general equation for making salts with carbonates
acid + carbonate —-> salt + water + carbon dioxide
what is the blue-green substance in some rocks called
malachite
what is malachite made from
copper carbonate
how are salts formed by neutralisation
when an acid reacts with an alkali it neutralises and produces a salt
what is the general equation for neutralisation reaction
acid + alkali —-> salt + water
what are metal oxides called
bases
what is the general equation for alkali and bases reaction
metal oxide + water —-> alkali
what is the basic reactivity series
potassium, sodium, calcium, magnesium, aluminium, zinc, iron, lead, copper, silver, gold
