Question

1) End Point- Point in titration at which a reaction is complete. The point during a titration when an indicator shows that the amount of reactant necessary for a complete reaction has been added to a solution.

2)Equivalence point-  At equivalence point, the moles of a standard solution (titrant) equals the moles of a solution of unknown concentration (analyte).

3)The difference in the amount of titrant, or the corresponding difference in the amount of substance being titrated, represented by the expression: (end-point value - equivalence-point value).

2)If any bubbles gets trapped inside the nozzle,open the nozzle and let some fluid to pass through the nozzle till the air bubbles are removed.It is necessary to prevent any titration error.

3) 2KMnO4+3H2SO4+5H2C2O4.2H2OK2SO4+2MnSO4+18H2O+10CO2

Therefore for every 1 mole of KMnO4,5/2 moles of crystalline oxalic acid react.

Explanation / Answer

Note: Some of these questions are derived from "Introduction to Volumetric in Appendix. 1. Define the end-point, equivalence point, and titration error of a volumetric analysis. Analysis,' the and equivatonee Post 2. Sometimes a bubble of air gets trapped in the nozzle of a buret. How should it be removed, and why shoald it be removed it we yensved by a 3. For each mole of KMnOs that reacts in this experiment, how many moles of H C,0 2H-O react?
