A solution with pH 7 is generally what type of solution?

Answer and explanation

Correct answer: Neutral

At about 25°C, pH is a logarithmic measure related to hydrogen-ion concentration: pH = −log[H⁺]. A pH of 7 indicates equal effective concentrations of hydrogen and hydroxide ions in a neutral solution, so option C is correct. Values below 7 are acidic and values above 7 are basic. The word “generally” is important because neutrality and the exact pH scale can depend on temperature, but the school-level classification remains pH 7 as neutral.
