What does the pH of a solution measure? O A. Color
O B. Volume
O c. Temperature
O D. Acidity

D is the correct answer acidity

Explanation:

pH is the logarithmic measurement of the H3O+-concentration in water solutions.

By definition: pH = -log[H3O+]

Example: [H3O+] = 1.0*10-7 mol/L in neutral, pure water (at 25oC), so

pH = -log(H3O+) = -log(1.0*10-7) = 7.0

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

the answer is true.
