Help with 2 pleaseor 1.25rlo nales 2) A student performs an aqueous titration between an unknown polyprotic acid with a known concentration of strong base. A pH vs. mL of NaOH graph yields quantitative information that show multiple equivalency points. By performing a derivative on these data, the student will more easily determine ,. .the volume of strn acid requred to atin he butter epors b. ..the volume of strong base required to attain the equivalency points. c. ..the volume of acid and base required to attain zen moments. d. ..the pH of the strong acid True or False: If the statement is FALSE, then please draw a line through a portion of the word or sentence and rewrite the statement so that becomes TRUE d with ctrong hase in the nresence of water, you
Explanation / Answer
Answer
choice (b) is correct.
In the graph of pH vs. mL of NaOH sol.
pH is on Y-axis and vol. of NaOH on X-axis,
When we take first derivative, it gives a sharp peak from which we have to draw a perpendicular line on X-axis to get vol. of NaOH.
In second derivative also, the graph sharply cut the X-axis which determines the vol. of NaOH to attain equivalence point.
