the last part of this standard focuses on Acids and Bases.
you can find some summary notes here.
Key points are
An acid is defined as a proton donor (An acid loses a proton, or H+ ion and 'donates' it to a base (usually water)
An alkali/bases if defined as a proton acceptor (A base will accept a proton from an acid)
- Strong acids and alkalis/bases completely dissociate.
- Weak acids and alkalis/bases only partially dissociate

| When an acid (or base) reacts to lose (or gain) a proton, it forms a conjugate base (or acid) pair. For example, for the acid HCl, Cl- is the conjugate base. For the base NH3, NH4+ is the conjugate acid. |
For your assessment you also need to be able to calculate the pH/pOH/[H3O+]/[OH-]. How to do this is below - make sure you can use your calculator before the exam :-)
