Question

What is the ph of a 0.01 m solution of the strong acid hno3 in water?

Answer 1

Answer is: pH of a 0,01 M solution is 2.
c(HNO₃) = 0,01 M = 0,01 mol/L.
pH = -log(c(HNO₃).
pH = -log(0,01 mol/L).
pH = 2.
pH is a numeric scale used to specify the acidity or basicity of an aqueous solution. 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.

Answer 2

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
