some tips to minimize errors with your classmates.
3. What is an example of a problem that could be solved using a titration in the
real world? Comment on other students' ideas.
4. Phenolphthalein was used as the indicator in this experiment. The universal
indicator exhibits a rainbow of colors for the entire pH range. Do you think
using the universal indicator would also work for this lab? Justify your answer
and comment on another student's answer to explain why you agree or
