Answer to Question #74582 in General Chemistry for George

Question

1.50 grams of HNO3 is added to water to obtain a final volume of 700.0 ML. What is the final concentration of H+?

Answer 1

Solution
Nitric acid is a strong electrolyte and dissociates completely in solution:
HNO 3 = H + + NO 3 -
Calculate the number of moles of nitric acid: n(HNO 3 )=
We find the concentration of hydrogen ions, which is equal to the concentration of nitric acid:
[H + ]=c(HNO 3 )=
Answer: [H + ]=0.034
