Calculate the ph of an acid solution containing 0.10 m hno3

Considering the definition of pH, the pH of an acid solution containing 0.10 M HNO₃ is 1.  

You need to know that pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:

pH= - log [H⁺]

On the other side, a strong acid is an acid that completely dissociates into hydrogen ions and anions in solution at constant temperature and pressure. Under these conditions, the concentration of a strong acid equals the concentration of hydrogen ions.

In this case, HNO₃ is a strong acid, so:

[HNO₃]= [H⁺]= 0.10 M

So the pH can be calculated as:

pH= - log (0.10 M)

Solving:

pH= 1

Finally, the pH of an acid solution containing 0.10 M HNO₃ is 1.

The pH would be 1.

Explanation:

The pH of an acid can be found by using the formula pH = - log [H⁺]. This was a method developed to be able to measure the pH of substances.

Since the concentration of HNO₃ is 0.1 M, then it also means that the concentration of H⁺ ions is 0.1 M.

By substituting for the formula: pH of 0.1 M HNO₃ = - log [0.1]
