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,
red).…read more

Forming Acids
They all ionize in water to form hydrogen
ions (H+ ions).
1) HCl H+ + Cl- (chloride)
2) HNO3 H+ + NO3- (nitrate)
3) H2SO4 2H+ + SO4-2 (sulphate)…read more

Here's a taster:

Non-metal Oxides
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
oxide.…read more
