If a solution has a very low pH value, which statement is correct about it?
Answer and explanation
Correct answer: It is highly acidic
The pH scale indicates the acidic or basic nature of an aqueous solution. A lower pH means a greater concentration of hydrogen ions, so the solution is more acidic; a higher pH indicates a more basic solution. Therefore, option A is correct. Option B reverses the pH relationship, while pure water is approximately neutral and contains ions from the slight ionisation of water.
