if a diluted nitric acid solution has a concentration of 0. 0001 M. The solution's pH value is 4.
What exactly is pH?
The pH scale, which ranges from 0 to 14, is used to determine whether a material is acidic, basic, or neutral.
How can I determine the pH of a solution?
The hydrogen ion is represented to compute the pH. Here it is expressed:
pH = - log[H⁺]
Therefore, in case of the nitric acid(HNO₃) ,the concentration of hydrogen ion = 0.0001 M.
So, pH = - log[0.0001]
⇒pH = -log(1/10000)
⇒pH = -log(10)⁻⁴
⇒pH = -4 x -log(10)
⇒pH = -4 x (-1)
⇒pH = 4
Therefore it is concluded that the pH of the nitric acid solution is 4.
