Unit 2 AQA Chemistry Acids Bases & Alkalis

Acids has a Ph of less than 7. They are corrosive.

Definiton of Acid: They produce Hydrogen ions in water. Also definied by proton   doners. (ie/ they give protons, quite kind of them really)

Examples: Hydrochloric Acid. Sulphuric Acid Nitric Acid, Phosphoric Acid, Ethanoic Acid, Citric Acid...you get the idea...

Alkalis have a Ph of greater than 7.

Definition of Alkalis: They produce hydroxide ions (OH- ) when dissolved in water.

Examples: Sodium Hydroxide, Potassium Hydroxide, Calcium Hydroxide (aka limewater, remember that unit 1 stuff? nope, neither do…
