If the concentration of a dilute solution of nitric acid is 0. 0001 m. What is the ph of that solution?
1 answer:
If the concentration of a dilute solution of nitric acid is 0. 0001 M. The pH of the solution is 4.
<h3>What is pH ? </h3>pH is used to measure whether the substance is acidic, basic or neutral and the range is 0 - 14.
<h3>How to find the pH of the solution ?</h3>To calculate the pH hydrogen ion it is expressed as:
pH = - log [H⁺]
So, concentration of hydrogen ion in HNO₃ is 0.0001 M.
pH = - log [0.0001]
=
= - log (10)⁻⁴
= -4 × - log (10)
= - 4 × (-1)
= 4
Thus from the above conclusion we can say that The pH of the solution is 4.

Answer:
2.07 mol O₂
Explanation:
First we need to write down the species present in the chemical equation, using the information given by the exercise:
- H₂S + O₂ → SO₂ + H₂O
However this equation <em>is not balanced</em>, so now we<u> balance it</u>:
- 2H₂S + 3O₂ → 2SO₂ + 2H₂O
Now we can use the stoichiometric ratio to <u>calculate the moles of oxygen </u>from the moles of sulfide dioxide:
- 1.38 molSO₂ *
= 2.07 mol O₂
