If an aqueous solution has pH close to 14, what careful conclusion should be taken while handling it?

Answer and explanation

Correct answer: It may be highly basic and caustic

On the usual aqueous pH scale, values near 14 indicate a very high concentration of hydroxide ions and strong basic character. Such a solution may be caustic, meaning it can damage skin, eyes, or other tissues. The pH value alone does not make a substance pure, edible, or acidic, so careful handling with goggles, gloves, and proper laboratory practice is required. Therefore A is correct; B, C, and D contradict the meaning of high pH.
