REVISION NOTES
IGCSE Edexcel Chemistry
4.6 Carboxylic Acids
4.6.1C Know that carboxylic acids contain the functional group -COOH
The functional group of carboxylic acid is -COOH
4.6.2C Understand how to draw structural and displayed formulae for unbranched-chain carboxylic acids with up to four carbon atoms in the molecule, and name each compound
4.6.3C Describe the reactions of aqueous solutions of carboxylic acids with metals and metal carbonates
REACTION OF CARBOXYLIC ACIDS
- Carboxylic acids dissolve in water to produce acidic solutions
- So it can react as an acid
carboxylic acid + metal → salt + hydrogen
carboxylic acid + metal carbonate → salt + H2O + CO2 (bubbles are formed)
4.6.4C Know that vinegar is an aqueous solution containing ethanoic acid
VINEGAR
- Aqueous solution containing ethanoic acid
