Answer:
Smoke, heat, bubbles, precipitate, gas, and odor changes, and color change.
Explanation:
There needs to be more of a background on this lab. Although if this is the one I believe you are talking about, it should have turned pink. Since the PH is being changed your indicator changed from clear to pink (if you used the same indicator) this is when your PH from both of your substances are equal (or very close).
The observations that led to the chemical change in the reaction during titration can be smoke, heat, precipitation, gas, odor change, and color change.
The titration has been the neutralization reaction in which an acid reacts with the base for the formation of salt. The chemical reaction has been the taken place. This can be concluded with the presence of indicators in the solution. The indicator can help in the observation for determining the chemical change in the reaction.
The other observations that can indicate the presence of chemical change are smoke, heat, precipitation, gas, odor change, and color change.
