Concentration: Higher, Lower Or Unchanged?

[Joker37]

A student titrated an aliquot of standard sodium carbonate solution with hydrochloric acid in a burette. State whether the concentration determined for the hydrochloric acid would be likely to be higher, lower or unchanged compared with the actual value if the student had previously washed with water, but not dried, the following apparatus:

a)the pipette used to deliver the aliquot of sodium carbonate solution

b)the flask containing the aliquot

c)the burette.

 

 

Any help with the reasoning/explanation/walkthrough of the above question will be greatly appreciated! :)
