Which of the following practices best minimizes random error during an acid–base titration?
(a) Selecting an indicator whose color change occurs very close to the expected equivalence point
(b) Rinsing the inner walls of the Erlenmeyer flask with distilled water during the titration
(c) Reading the buret volume at eye level to avoid parallax
(d) Consistently swirling the flask while dispensing the titrant
