Interpretation Introduction

### (b)Interpretation:A titration curve should be constructedConcept introduction:Potentiometric titration is similar to direct redox titrations but in potentiometric titrations no indicator is used. Instead, the potential is measured during the titration to obtain the equivalence point.
