Answer:
a. The process illustrated by the setup is a chemical reaction between NaOH (sodium hydroxide) and HCl (hydrochloric acid) to produce salt (sodium chloride) and water.
b. The parts labelled I, II, and III are not specified in the question, so it is not possible to name them accurately.
c. The device used to introduce NaOH into the part labelled III is not specified in the question, so it is not possible to determine the correct answer.
d. The reaction between NaOH and HCl is a neutralization reaction, where the strong acid (HCl) reacts with the strong base (NaOH) to produce a salt (NaCl) and water.
e. The equation for the formation of salt by the setup is:
HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l)
