Defenition: When a substance dissolves in water, the solution may be acidic, neutral or alkaline.
Examples:
The three common acids you will find in the laboratory are;
Hydrochloric acid - HCl(aq), Nitric acid - HNO3(aq)
and Sulfuric acid - H2SO4(aq)
They are all strong acids - seepH.
They all ionise (make ions) in waterforming
hydrogen ions (H+ions). This is what makes them acids.
Hydrochloric acid
HCl(aq) H+(aq) + Cl-(aq)
Nitric acid
HNO3(aq) H+(aq) + NO3-(aq)
Sulfuric acid
H2SO4(aq) H+(aq) + HSO4-(aq)
These three acids…
