HNO3 increases the concentration of ____ when added to water

Answers

Since HNO3 is a strong acid, it would dissociate completely forming ions of H+ and NO3-. The ionization or dissociation of HNO3 will increase the concentration and or amount of H+ within the water, resulting in the pH or measure of H+ to decrease, indicating that the solution is tending to become acidic.

Convert 22.0 mL to L

Answers

0.022

One milliliter is equal to a thousandth of a liter, so divide by 1000..

Final answer:

To convert 22.0 mL to L, divide the given value by 1000.

Explanation:

To convert 22.0 mL to L, you need to use the conversion factor of 1 L = 1000 mL.

Therefore, to convert mL to L, divide the given value by 1000.

So, 22.0 mL = 22.0 mL / 1000 = 0.022 L.
