4. Whether soluble in
water or not,
carboxylic acids
react with aqueous
solutions of sodium
hydroxide (NaOH),
sodium carbonate
(Na2CO3), and
sodium bicarbonate
(NaHCO3) to form
salts:
RCOOH + NaOH(aq) →
RCOO−Na+(aq) + H2O
2RCOOH + Na2CO3(aq) →
2RCOO−Na+(aq) + H2O + CO2(g)
RCOOH + NaHCO3(aq) →
RCOO−Na+(aq) + H2O + CO2(g)
Here the carboxylic acids
act like inorganic acids: they
neutralize basic
compounds.

5. Let's
Practice...
CH3CH2COOH(aq) + NaOH(aq) →
CH3COOH + Na2CO3 →
HCOOH + NaHCO3 →
CH3COOH + CaCO3 →

7. Naming Carboxylic Acid Salts
 We name them in the same manner as inorganic
salts: the name of the cation is followed by the
name of the organic anion. The name of the anion
is obtained by dropping the -ic ending of the acid
name and replacing it with the suffix -ate. This rule
applies whether we are using common names
or IUPAC names:

8. Carboxylic Acids react with more reactive
Metals
 In the reaction they produce a salt and hydrogen
Examples:
CH3COOH + Zn →
HCOOH + K →
C2H5COOH + Mg →

9. Neutralisation
 As other acids, carboxylic acids react with base oxide or
alkali to produce salt and water
Examples:
HCOOH + CaO →
CH3COOH + NaOH →

10. Reactions with Ammonia:

11. Esterification
 Carboxylic acids react with alcohol with the presence of
concentrated sulphuric acid (________) as catalyst to produce ester
and water
Example:
CH3COOH + C2H5OH → CH3COOC2H5 + H2O
CH3COOH + CH3OH →
