If a student says acids should be identified only by taste, why is this method wrong?

Answer and explanation

Correct answer: Because many acids are harmful and indicators are safer

The governing principle is laboratory safety and objective testing. Some acids are corrosive, poisonous, or harmful to body tissues, so tasting an unknown substance can cause injury and is never an acceptable identification method. Indicators, pH paper, and controlled chemical tests provide safer evidence of acidic behaviour. Acids can have tastes, so B is false; taste cannot measure pH reliably, and indicators are not limited to metals. Hence A is correct.
