A definition of an acid is a substance that releases hydrogen ions, a hydrogen iron is a proton.
Bases is something that can take up H+, usually to make water.
Acid + base = salt + water
An alkali is a base that can dissolve in water.
Alkalis often have a hydroxide ion, OH
Common Acids
Hydrochloric acid (Hcl)
Nitric acid (HNO3)
Sulfuric acid (H2SO4)
Phosphoric acid (H3PO4)
Ethanoic acid (Ch3COOH)
Common vases and alkalis
Sodium hydroxide
Potassium hydroxide
Ammonium hydroxide
Sodium hydrocarbonate (bicarbonate of soda, in baking powder)
PH scale
pH = -log [h+]
‘Strong’ in this context means highly ionised
Weak means not much ionised
