Answer #1

Multicellularity has evolved multiple times

1) Curve on the left :-

Before addition of base pH=1 so this implies that the titration curve is of strong acid and strong base

Curve on the right :-

Before addition of base pH=3 so this implies that the titration curve is of weak acid and strong base

2) since the equivalence point is 7 so HCl of same molaity as NaOH can be used as a titrand

    Question: In the figure below, titration curves for strong acid with strong base and weak acid with strong base are shown. Compare the shapes of these curves early in the titration for three different cases: titration of a strong acid, titration of a weak acid with a lower pKa, and titration of a weak acid with a higher pKa. Discuss with the class why the titration curve for weak acids increase more rapidly early in the titration than do stronger...

Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...
