Answer:
Yes it will affect the outcome of the titration but The effect is negligible
Explanation:
The rinsing of the sides of the Erlenmeyer flask with distilled water will affect the outcome of the titration but not to a very large proportion( negligible ). and this incidence might occur if the flask is not allowed to dry up completely after rinsing. hence it is advisable to allow the flask to dry up very well before using it for titration purposes
