You identify acids and alkalis using indicators. Indicators are substances which turns a particular colour for acids and another for bases. E.g. litmus, (acid-red, alkali-green) and phenolphthalein. Indicators have a certain pH value. You can only use a particular indicator of a suitable pH value for a particular acid-base reaction
