The neutralization of 50 ml of 0.25 `NH_2SO_4` will require ____ ml of 0.50 N NaOH.

Options

A. 2.5
B. 0.25
C. 50
D. 25

Answer

D

Explanation

As long as the volume units are the same, `N_1V_1=N_2V_2`
`V_2=(N_1V_1)/N_2 =((50)(0.25))/0.50` = 25 ml
The fact that the acid produces two hydrogen ions per molecule does not enter into the calculations
