- The Oceans
- entropy and enthalpy
- entropy, S, - randomness of a system
- sparingly soluble substance is in equilibrium
- solubility product, Ksp
- the greenhouse effect
- visible radiation rapidly penetrate the atmosphere and warms the Earth
- invisible infrared radiation is emitted by the Earth and cools it down
- some of this infrared radiation is trapped by the greenhouse gases in the atmosphere which act as a blanket, keeping the heat in
- buffer solutions resist changes in pH when small amounts of acid or alkali added
- acid-base chemistry
- acid-base pair: conjugate acids/bases
- pH = -log[H+], [H+] = 10^-pH
- Bronsted-Lowry definitions: acid is an H+ donor, base is an H+ acceptor
- strong acids and weak acids
- pH of weak acids
- acid dissociation constant
- pH of strong acids
- ionisation product of water
- pH of strong alkalis
- ionisation product of water
- strong acids and weak acids
- dissolving
- ionic substances - energy supplied to overcome electrical attraction between oppositely charged ions in the lattice
- intermolecular bonds
- ionic bonds
- ion-dipole bonds
- enthalpy change of solution
- ion-dipole bonds
- ionic bonds
- ionic bonds
- ion-dipole bonds
- enthalpy change of solution
- ion-dipole bonds
