Answer:
The concentration of hydrochloric acid would be estimated to be less.
Explanation:
This is because, the hydroxyl ions from water react with the hydrogen ions from the hydrochloric acid, hence decreasing the moles of hydrogen ions which lowers the acidic strength of Hydrochloric acid.
If water was used to rinse the burette and the burette is then used to dispense hydrochloric acid solution, the final estimate of hydrochloric acid concentration will be less.
It is usual to rinse the burette with the solution that ought to be in it after rinsing it with water.
However, in this case, the burette was was rinsed with water alone and then it was used to dispense the hydrochloric acid solution.
The water will dilute the hydrochloric acid solution thereby making the final estimate of hydrochloric acid concentration to be less.
Hence, if water was used to rinse the burette used to dispense the hydrochloric acid solution, the final estimate of hydrochloric acid concentration will be less.
