2. During the titration of an acid with a base, the sides of the Erlenmeyer flask are washed with distilled water. Do you think this rinsing affected the outcome of the titration? Why or why not?

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

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
