Answer:
The titrant is a strong acid while the analyte is a strong base
Step-by-step explanation:
A titration curve is a graphical representation of the pH of a solution during a titration. The figure in the question shows a particular example of a strong acid-strong base titration curve. This is a titration in which the acid is added to the base thus the pH progresses from low to high.
Hence, the titrant is the strong acid delivered from the burette while the analyte is the base as shown by the titration curve in which acid is delivered to the base.
