What is the ph of a 0.0056 m hno3 solution? hint: hno3 is a strong acid. almost all of the acid will be ionized. select one: a. 2.25 b. 11.11 c. 1.25 d. 0.056 e. 12.75

The pH is 2.25 (A)

Explanation: The reaction of HNO3 is;

HNO3(aq) ==> H+(aq) + NO3-(aq)

From the reaction, the concentration of H+ is equal to concentration of HNO3, that is

[H+] = [HNO3] = 0.0056=5.6×10^-3

pH= -log [H+]

pH= -log [5.6×10^-3]

pH= 3 - log 5.6

pH = 2.25

Therefore the pH of 0.0056HNO3 = 2.25

idk what the question is about

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
