What volume of 20% Na2CO3 solution will be required to neutralize 25ml of decinormal H2SO4 solution? About the author Ariana
Answer: plz mark brainlist Explanation: Let normality of H 2 SO 4 =N N 1 V 1 =N 2 V 2 ⇒0.1×22.7=N×10.2 ⇒N=0.2225 Now the number of equivalent present in 400ml solution= N×400 =0.2225×400=89meq For making the solution of 0.1N, Let V ml of solution is needed ⇒0.1×V=89 V=890ml Hence the volume of water that must be added is 400ml ∴V=890−400=490ml Reply

Explanation:
Let normality of H
2
SO
4
=N
N
1
V
1
=N
2
V
2
⇒0.1×22.7=N×10.2
⇒N=0.2225
Now the number of equivalent present in
400ml solution= N×400
=0.2225×400=89meq
For making the solution of 0.1N, Let V ml of solution is needed
⇒0.1×V=89
V=890ml
Hence the volume of water that must be added is 400ml
∴V=890−400=490ml
