As the atmospheric pressure decreases, the temperature at which water boils decreases too. An increase in pressure leads to an increase in boiling point while a decrease in pressure leads to a decrease in boiling point.
Hello!
If there's an air bubble inside the buret, and the bubble escapes the buret during the titration the initial volume lecture (Vi) would be lower (closer to 0) than the actual one, and the recorded consumed volume (ΔV=Vf-Vi) would be higher than the actual one and thus the calculated concentration of the hydrochloric acid would be higher than the real one.
Have a nice day!
