the first four carboxylic acids are:
methanoic
acid
ethanoic
acid
propanoic
acid
butanoic
acid
carboxylic acids react with
carbonates
they produce
salt
,
water
and
carbon
dioxide
salt ends in
-anoate
e.g ethanoic acid + sodium carbonate ->
sodium
ethanoate
+
water
+
carbon
dioxide
carboxylic acids can
dissolve
in
water
they
ionise
and release
H+
ions, so
acidic
solution produced
they do not
ionise
completely, so, form
weak acidic
solutions
have higher
pH
carboxylic acids can reat with
alcohols
to form
esters
an
acid catalyst
is used
water
is produced
e.g ethanoic acid + ethanol ->
ethyl ethanoate
+
water
