You have just started working at a swimming pool supply store and they have nitric acid on their shelves. In order to help customers adjust the pH of their swimming pool you must know many details about this chemical. Due to air conditioning the store is always at 25 degrees Celsius. The label on the nitric acid bottle is marked as 0.0155 mol/L. What is the hydronium ion concentration?

Respuesta :

Answer:

The concentration of hydronium ions is 0.0155 mol/L

Explanation:

The aqueous solution ionization reaction for nitric acid is as follows;

HNO₃ + H₂O → NO₃⁻ + H₃O⁺

Whereby HNO₃ is a strong acid and it undergoes complete ionization in an aqueous solution

Hence one mole of HNO₃ produces one mole of H₃O⁺ ions

0.0155 mol/L HNO₃ will have 0.0155 moles of H₃O⁺ in one liter of the solution

The concentration of hydronium ions = 0.0155 mol/L.
