The acids are sour in taste while bases
are bitter in taste. Tasting a substance
is not a good way of finding out if it is
an acid or a base. Acids and bases can
be better distinguished with the help of
indicators. Indicators are substances that
undergo a change of colour with a change
of acidic, neutral or basic medium. Many
of these indicators are derived from natural
substances such as extracts from flower
petals and barrier. Some indicators are
prepared artificially. For example, methyl
orange and phenolphthalein.
