Answer :
The volume of solution required to make final concentration of is 2.5 ml and for is 3 ml.
What are calibaration of a solution?
Standard addition, internal standard, and external standard techniques to quantitation all employ calibration solutions. Calibrants can be made gravimetrically using reference standards or pure reference materials, but they can also be made on a volumetric or other fraction basis.
For preparing the solution of known concentration and volume, the equation can be related as:
M1v1=M2V2
M1 and V1 are molarity of known solution
M2 AND V2 molarity of solution to be prepared
Here,M1=1 x 10^-4M
M2= 1 X 10^-5 M
V2= 25ml
1 x 10^-4 x V1=1 X 10^-5 x 25
Volume of required solution=2.5ml
To make the volume 10ml of 3 x 10^-5 x 10
Volume of required solution=3ml
Therefore the volume of solution required to make final concentration of is 2.5 ml and for is 3 ml.
