Question

Volhard’s method of performing this technique involves first mixing excess silver nitrate with a saline solution. For 10 points each:
[10e] Name this technique to determine the concentration of an analyte. The “acid-base” form of this technique involves slowly adding an acid or base to a solution until an indicator changes color.
ANSWER: titration [accept acid-base titration]
[10h] At this point in an acid-base titration, the pH and pKa of the solution are equal, meaning the concentration of the weak acid equals the concentration of the conjugate base.
ANSWER: half-equivalence point [reject “equivalence (point)”]
[10m] In the Volhard method, silver chloride undergoes this process by settling out of solution to indicate the equivalence point. Compounds with a low Ksp (“K-s-p”) more easily undergo this process.
ANSWER: precipitation [accept word forms like precipitate]
