Giải thích tại sao phản ứng thế ai điện tử SE vào naphtalen vào vị trí Anpha là

Yes.

Explanation:

Yes, I agree with Bryce and his lab partner because titration is completed when the solution changes its colour. Add chemical from the burette until the solution change its colour so then calculate the amount of chemical is used from the burette and the time at which the titration is completed. Always be careful for calculating the titration in order to get accurate data of the solution.
