Question 813296
Nitric Acid is a strong acid, so is completely ionized dissolved in water.
{{{HNO[3]}}}, 63.01 grams per mole.  pH is based on MOLARITY, so also since hydronium to nitric acid is 1:1 mole ratio,


{{{(12.2/(1))*(1/63.01)=0.194}}} M, both hydronium and nitric acid

That is assuming the 12.2 grams is a very small change in volume, which might be incorrect, but the difference in pH will be very, very small.


you now want {{{highlight(-log(10,0.194)=0.71)}}}


Yes, it is a very low pH.
