Question
After transfering the completely dissolved NaOH to the volumetric flask from the beaker, the beaker was washed with distilled water. What will happen to the apparent concentration of the solution if the beaker used to dissolve the NaOH was not covered with glass and the distilled water used to wash the beaker was disposed of in the sink?
Select one:
a.
The concentration will decrease because the NaOH may evaporate
b.
The concentration will decrease because there may be NaOH present in the distilled water used to wash the beaker
c.
The concentration will not change because all NaOH was transferred to the volumetric flask
d.
The concentration will increase because the water may evaporate
