Question

1. In titrations, what is the difference between the equivalence point and the endpoint? 2. In a titration reaction, 45.6 mL of 0.047 N NaOH was needed to neutralize 30.1 mL of H,SO4. Calculate the following measures of concentration. a. The normality of the acid solution b. The molarity of the acid solution

Answer 1

- » The equivalence point of a titration is the point at which the added titrant is chemically equivalent completely to the analyte in the sample End point is the point where the indicators Chanses its color. Dequivalence point comes before the end Point. End point is where you see a color change n indicator added to the titration solution on you add phenopthalein For instance when you add Phenopthe to titrate entoric acid with Sodium hydroxide , ite the t at which there is a color change hydrochloric acid Point at whie manent to the solution. there is point and the difference end point. : so, in the above netween equivalence CS Scanned with CamScanner
