Question

Four standard titration curves (A, B, C, D) are visually plotted representing SA-SB, WA-SB, SA-WB, and WA-WB titrations respectively. Which of the following visual characteristics properly map to their respective titrations?

Prashant Kotian · Accepted Answer

Correct answer: A,B,C. Strong Acid-Strong Base (SA-SB) titrations exhibit the largest visual pH jump at equivalence. WA-SB starts less acidic (higher pH) and its anionic hydrolysis pushes the equivalence point visually above pH 7. SA-WB ends with cationic hydrolysis, pushing the equivalence point visually below pH 7. A WA-WB titration curve completely lacks a sharp vertical visual jump at equivalence because the solution behaves like a buffer throughout, making indicator detection extremely difficult.
