What is the concentration of a nitiric acid (HNO3) solution if 100.0ml of 0.50M NaOH are needed to neutralize 40.0ml of the nitric acid solution?

Answer 0,36 M

Hello!

The general chemical equation for the neutralization of an acid HA with NaOH is the following:

HA (aq) + NaOH (aq) → NaA (aq) + H₂O (l)

For determining the concentration of the acid solution, we can use the equation shown below:

So, the concentration of the Acid is 0,36 M
