Answer to Question #50368 in Chemistry for Meagan

Question

What volume of 5.0 M HNO3 is required to neutralize 2500 cm3 of a 2.0 M NaOH solution

Answer 1

The chemical equation for the reaction is:
NaOH+ HNO₃ = NaNO₃ + H₂O
According to the equation the number of moles of the acid is equal to the number of moles of the base.
n(NaOH)= n(HNO₃)
n(mol)= C(M)∙V(L)
C(NaOH)∙V(NaOH)= C(HNO₃)∙V(HNO₃)
2.0M∙ 2.5L = 5.0M∙V(HNO₃)
V(HNO₃)=(2.0∙2.5)/5.0 = 5.0/5.0 = 1 L
Answer: V(HNO₃)=1 L
