GCSE Chemistry Unit 3 revision notes

C3 2.1 Strong and weak acids/alkalis

- Acids in aqueous solutions produce H+ ions

- Alkalis in aqueous solutions produce OH- ions

(H+) Acids = proton donors. This is because they are positive ions, and so can act as a source of protons.

(OH-) Alkalis = proton acceptors. This is because they can combine with protons to form water.

- All strong acids/alkalis are 100% ionised…
