If a solution has pH close to 14 and feels slippery on skin, what is the safest conclusion?

Answer and explanation

Correct answer: It may be strongly basic and caustic

The pH scale identifies how acidic or basic an aqueous solution is: values near 14 indicate a very strong base. A slippery feel is also commonly associated with alkaline solutions because they react with skin oils, but touching an unknown chemical is unsafe. Therefore option A is correct: it may be strongly basic and caustic. Pure water is near pH 7, a mild acid has pH below 7, and common salt solution is approximately neutral.
