Does it matter if you spray a bit of water at the tip of your burette when titrating strong base into strong acid, i.e. does it change the equivalence point?
It decreases the concentration of your acid solution, so you may need to swirl your solution more every now and then to ensure that the titrant is distributed throughout the solution.
However, the number of
Say you have
#"0.50 mol"/"L" xx "0.10 L" = "0.05 mols H"^(+)#,
you would have
#"0.25 mol"/"L" xx "0.20 L" = "0.05 mols H"^(+)#
So you would still have the same
The difference is that what you're titrating now "harder to find", because it's a more dilute solution. You can still add titrant by dripping slowly, but you have to be more careful not to add too fast without checking, now that it's harder to successfully neutralize what you're titrating.
