What is the ph of a 2.0 x 10^-4 m solution of nitric acid (hno3)

Hello!

datos:

Molarity =

ps: The ionization constant of the nitric acid is strong (100% ionized in water) or completely dissociates in water, so the pH will be:

Note:. The pH <7, then we have an acidic solution.

I Hope this helps, greetings ... DexteR!

The pH of the nitric acid solution is 3.70.

Explanation:

The pH is negative logarithm of hydrogen ion concentration.

Concentration of nitric acid =

1 mole of nitric acid gives 1 mole of hydrogen ions.

Then of nitric acid will give .

The pH of the solution :

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
