- Acids and bases
- Bronste lowry acids and bases
- an acid is a substance that can donate a proton. A base is a substance that can accept a proton.
- water = amphoteric . forms oxonium ion with acid and acts as an acid with bases
- slightly ionised - 1 water molecule gives a proton to another forming H+ and OH-
- [H]+ = 1.0x10-7 = [OH]-
- slightly ionised - 1 water molecule gives a proton to another forming H+ and OH-
- PH
- -log10 [H+]
- smaller ph = more H+
- -log10 [H+]

- Bronste lowry acids and bases
- PH of water different at different temberatures, as dissociation is endothermic.
- smaller ph = more H+
- slightly ionised - 1 water molecule gives a proton to another forming H+ and OH-
- [H]+ = 1.0x10-7 = [OH]-
- always neutral however as OH- concentration always equals H+ concentration
