1 of 8
Give 4 acidic properties of the -OH group?
1. All proton donors. 2.Carboxylic acids & phenols form salts with strong bases. 3. Weak Acids - partially ionised in solution. 4. Only carboxylic acids - ionised enough to produce sufficient H+ to liberate CO2 from aq carbonate or Hydrogen Carbonate
