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
