Which precaution is most suitable while handling a solution of pH 13?
Answer and explanation
Correct answer: Use gloves and goggles
The governing concept is the relationship between pH and alkalinity, together with laboratory safety. A pH of 13 indicates a strongly basic solution with a high hydroxide-ion concentration; it may irritate or damage skin and eyes. Gloves and goggles reduce exposure and protect these tissues, so option A is correct. Tasting, direct touching, and storing it in a drink container are unsafe practices, not precautions.
