Acids & Bases
·3.3.46 recognise that acids dissolve in water,
producing hydrogen ions (H+), that alkalis dissolve in
water producing hydroxide ions (OH-) and that
neutralisation is the combination of these ions to form
·3.3.47 recognise that a base is a metal oxide or
hydroxide and that an alkali is a soluble base.…read more
Examples of Acids.
The three common acids you will find in
the laboratory are
1) Hydrochloric acid - HCl(aq)
2) Nitric acid - HNO3(aq)
3) Sulphuric acid - H2SO4(aq)
They are all strong acids ( have a pH of 1,
The Oxides of non-metals are acidic.
When non-metal gases dissolve into water
acids are produced:-
CO2 - carbonic acid, H2CO3,
NO2 - nitric acid, HNO3,
SO2 - sulfuric acid, H2SO4.
Non-metal oxides dissolve in water to give
acidic conditions, metal oxides give basic
conditions and water is the only neutral
