Why is identifying acids and bases by taste prohibited in the laboratory?

Answer and explanation

Correct answer: They can harm the body

The governing principle is laboratory safety. Unknown acids and bases may be corrosive, poisonous, or harmful even in small amounts, so tasting them can cause burns, poisoning, or internal injury. Their identity and pH must instead be tested with suitable indicators, pH paper, or approved laboratory procedures. Therefore option A is correct; the other choices make false claims about sweetness, colour, or the accuracy of taste.
