Question

For each of the following three errors EXPLAIN if the calculated in lab (concentration of KMnO4 of H2O2 in bleach ) would have been higher or lower and HOW the errors would have affected these values if they had occurred Hint consider how each error affected KMnO4 delivered A student adds a steady stream of KMnO4 and does not slow down to add it drop-by-drop near the end point during the titration of the FAS samples A student reads the top of the meniscus milead of the bottom for every volume reading in this experiment A group of Students dispense and measure all 3 of their bleach solutions at one time at on time beginning of pan B of the experiment

Explanation / Answer

a. this will lead to excess addition of kmno4 and hence the ended point will not be observed because even one drop of excess kmno4 will change the end point.

b.in this case the end point obsever will be more hence it will change the final value.

c. The end point will be decresed as the volume of solution is more. as molarity is calculated as mol/litre
