1. 10.3 Strong and Weak Bases LO: I understand the difference between strong and weak bases.

2. 10.3.1 Strong Bases A base is a substance that an acid. LO:I understand the difference between strong and weak bases. A strong base is a substance that is fully ionised to give ions when dissolved in water. e.g. sodium hydroxide: NaOH(s) + waterNa + (aq) + OH - (aq) hydroxide neutralises

3. 10.3.2 Weak Bases LO:I understand the difference between strong and weak bases. A weak base is a substance that is only ionised to give hydroxide ions when dissolved in water. e.g. ammonia solution: NH 3 (aq) + H 2 O(l)NH 4 + (aq) + OH - (aq) 99.6% of the ammonia remains as. The equilibrium lies very much to the.left covalent molecules partially

4. Has a pH 10.3.3 Comparing Strong and Weak Bases In comparison to a strong base, a weak base: LO: I understand the difference between strong and weak bases. lower Reactions of Bases Has a conductivity Reacts at a rate. lower slower The stoichiometry is for equimolar strong and weak bases. identical
