Question

what is H+ in 1.0 L solution that contains 0.2 M of NH4cl ?​

Answer 1

Answer:

Concentration oF NH

4

OH=0.2M

Concentration of NH

4

Cl=0.2M

Concentration OF HCl=0.001M

K

b

=2×10

−5

Applying Henderson Equation

POH=P

K

a

+log[

base

]

POH=5−log2+log

0.2

0.2

=5−log2

Hence,

[OH
