Answer:
0.25 moles
Explanation:
The molar mass of NaOH is 40 g/mol.
This equals 0.25 moles
Answer:
Answer
Correct option is
A
9
pK
b
=−logK
b
=−log10
−5
=5
A mixture of ammonium hydroxide and ammonium chloride forms basic buffer solution.
The Hendrson's equation for he basic buffer solution is as given below.
pOH=pK
b
+log
[acid]
[salt]
Substitute values in the above expression.
pOH=5+log
0.1
0.1
=5
Hence, the pH of the solution is pH=14−pOH=14−5=9
