False
The stirring allows fresh solvent molecules to continually be in contact with the solute. If it is not stirred, then the water right at the surface of the solute becomes saturated with dissolved sugar molecules, meaning that it is more difficult for additional solute to dissolve.
Explanation:
According to the law of dilution,
The given data is as follows.
= 0.4782,
= ?
= 0.025
,
= 250 mL
Hence, we will calculate the value of
as follows.
=
= 13.07
Thus, we can conclude that we need 13.07 mL 0.4782 M sodium thiosulfate solution using pipette.
