0.101 M HNO3 vol 0.501 M NaOH 12.7 mL

What volume of 0.101 M HNO3 is required

to neutralize each of the following solutions?

a. 12.7 mL of 0.501 M NaOH

b. 24.9 mL of 0.00491 M Ba(OH)2

c. 49.1 mL of 0.103 M NH3

d. 1.21 L of 0.102 M KOH

HNO3는 1가 산

---> a = 1

NaOH는 1가 염기

---> b = 1

(1) (0.101 M) (? mL) = (1) (0.501 M) (12.7 mL)

? = [(1) (0.501) (12.7)] / [(1) (0.101)]

= 62.997 mL

답: 63.0 mL
