8. Properties & Reactions of Alcohols
pH7
What is the pH of alcohol in water?
What do you observe when sodium is added?
DEMO ADDDING UNIVERSAL INDICATOR TO WATER; demo sodium added to ethanol in test tube..
Explain that alcohols can be oxidised by the air or by using chemicals, this forms carboxylic acids.
What gas is formed?

10. Properties & Reactions
of Carboxylic Acids
What do you observe when 1moldm-3 HCl is added to calcium carbonate?
What do you observe when 1moldm-3 ethanoic acid is added to calcium carbonate?
But slower…
Demo adding HCl to CaCO3.
Demo adding Ethanoic acid to CaCO3 Strong and weak acid… what is the difference.. Strong ionises completely.. Weak ionises partially.. ALL turned to H+, only a few turned to H+ (what makes an acid an acid)
Explain that alcohols can be oxidised by the air or by using chemicals, this forms carboxylic acids.
What gas is formed?
