Answer to Question #77430 in General Chemistry for Dominique

Question

If instead of using HNO3, you used HCl with the same volume and concentration as HNO3, would you use the same volume of NaOH to reach the endpoint? What about using H2SO4?

Answer 1

1. NaOH + HCl = NaCl + H₂O
2. NаOH + HNO3 = NаNO3 + H2O
3. 2NaOH + H2SO4 = Na2SO4 + 2H2O
In the first and second cases of the used acid will be the same. Вut with the interaction of hydroxide with dibasic acid, the hydroxide volume will be 2 times greater than in the previous examples. This is based on the law of equivalence.
