Answer is: pH <span>of a 0,01 M solution is 2. c(HNO</span>₃) = 0,01 M = 0,01 mol/L. pH = -log(c(HNO₃). pH = -log(0,01 mol/L). pH = 2. pH<span> is a numeric scale used to specify the </span>acidity<span> or </span>basicity<span> of an </span>aqueous solution<span>. If pH is less than seven, than solution is acidic and if pH is greater seven, solution is basic, if pH is equal seven, solution is neutral.</span>
The pH = - log (H+) a 0.01 solution of a strong acid HNO3 in water contains 0.01 M of hydrogen ions(H+) Therefore, pH = - log (0.01) = 2 Therefore, the pH is 2
