Final answer:
It is false to use the same indicator for the titrations with hydrochloric acid of both sodium carbonate and sodium borate as they have different equivalence points; specific indicators may be required for each substance.
Step-by-step explanation:
The statement that the same indicator will be used for the titrations with hydrochloric acid of both sodium carbonate and sodium borate is false.
An important aspect of a titration experiment is identifying the end point, at which the moles of acid equals the moles of base, and this is typically indicated by a pH-sensitive dye known as an indicator.
The choice of indicator depends on the acid and base being used, as well as the expected pH at the equivalence point.
Sodium carbonate and sodium borate are different substances and will have different equivalence points when reacting with hydrochloric acid; therefore, they often require different indicators to determine the endpoint of the titration accurately.
