What is the nature of a solution when its pH is greater than seven?

Answer and explanation

Correct answer: Basic

On the pH scale, a value of 7 is approximately neutral at room temperature, while a value greater than 7 indicates a basic or alkaline solution. Therefore option B is correct. Such a solution has relatively fewer hydrogen ions and greater hydroxide-ion influence, and it can turn red litmus blue. An acidic solution has pH below 7; neutral is around 7, and “salty” does not by itself define pH.
