What is oxidation (in terms of electrons)
the loss of electrons becuase the of the gaining of oxygen
What is reduction
The gain of electrons because of the removal of oxygen
when metal reacts what happens in terms of electrons
they loose electrons then they form positive ions
what does redox mean
means one substance has lost oxygen and one has gained it (oxidation and reduction occur together)
what type of reaction occurs between an acid and a base
a nuturalistion reation
what are the products when a metal carbonate is reacted with an acid
salt, carbon dioxide and water
do all carbonates react with acids
yes
how do you get soluble salts back from the solution
evapouration / crystalisation
what pH range is acidic
1-6
what substances can neutralise acids
alkalis
what is filtering used to seperate
insoluble solids from liquids
what are bases
the metal oxides and hydroxides, that neutralise acids, that are insoluable in water
what is the bowl that you evaporate things in called
an evaporation basin
what do ionic equations show
they only show the substances being oxidised and / or reduced
what is this
a burrettre
what do acids form in water
H+ ions
what do alkiline solutions contain
OH- ions
