How many moles of Hions are present in the following aqueous solution? 3.3 mL of a 0.65 M nitric acid:

Nitric acid is a strong acid meaning it completely dissociates in water. Therefore, you can say that the concentration of H+ ions in solution is the same as the concentration of the acid (molar concentration). So once you have that, you can use the pH formula to find the pH of the acid.

pH = -log[H+]

So if you have .15 M HNO3 the pH is 0.82.

But, if you have a different concentration, the pH will change.

Explanation:

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice
