Question

What is the molarity of an NaOH solution if 3.47 mL is titrated by 11.1 mL of 0.0904 M HNO3?

Answer 1

Mole ratio between HNO3 and NaOH is 1 : 1
NaOH + HNO3 ---> NaNO3 + H20
so use the formula,
NaOH <---> HNO3
C1V1 = C2V2
put the values and find C1 for NaOH.

Answer 2

since both are strong species, titration of a strong base by a strong acid, you can apply the C1V1=C2V2 equation, or MV=MV

Answer 3

thank you
