Why KmnO4 is used as self indicator?
As we all know that the potassium permanganate (KMnO4) is the dark purple color solution ...and in titration it become colorless ....so when the titration is completed ...and the other single drop of KMnO4 solution produce pinkish colour in a beaker ...which indicate that the reaction was completed just a single drop before .. we use indicator in a a reaction in order to indicate ...but we dont used indicator in titration with KMnO4 because it also indicate us by changing its color ...colorless to pink
Why does the pH change rapidly at the equivalence point of a titration?
The equivalence point represents a region where the amount of acid to base (or base to acid) concentration is equal. Before the equivalence point there is a greater amount of acid (or base, depending on the titration). After the titration there is a greater amount of base (or acid). This reverse in dominance results in a dramatic change in pH.
Why do athletes eat bananas before a strenuous activity?
potassium
Do you need to fast before a serum potassium level is drawn?
yes
What is The process of adding a known amount of solution of known concentration to determine the concentration of another solution is called?
titration is the best method to determine the unknown concentration of the unknown. if ur known is a solid then you would have to used distilled water to ensure it is submerged before you titrate.
Why do you have to warm the oxalate solution before performing titration?
because if the temperature is too low the interaction between the oxylate and potassium permanganate will move too slow?? why IDK
Why is the vinegar diluted before titration?
1. The advantage in diluting the solution before titration is that it allows for greater accuracy in the titration; this is because the color change in the solution is easier to observe if it is a dilute solution.
Why the solution is boiled before titration?
because in those cases, the endpoint will not be correct if the titration is carried out at low temperature
Where is the buffer region in a titration curve for the titration of a weak acid with a strong base?
It is the nearly horizontal region before the equivalence point.
Why oxalic acid is acidified before titration?
for medium produce
Why do you need to remove the funnel before carrying out the titration?
chicken
Why potassium oxalate is acidified before titration?
If the temperature is too low (below 55 degrees celsius), the interaction between the oxalate and the potassium permanganate will move too slow as to be used as a practical lab experiment. *** Above 60 degrees celsius, oxalate acid begins to decompose, so it's important to stay in this range.

What is the pH of the solution before the titration?
This depends on what kind of solution you are about to titrate.
Why is it important to remove the CO2 from the solutions before doing the titration?
It is important to remove the carbon dioxide from the solutionf before doing the titration because, carbon dioxide mixed with water is acidic, it produces an acid.
Why oxalic acid is heated before titration with KMnO4?
Oxalic acid is generally warmed slightly because it is not completely soluble and heat helps this. It aids in accuracy of the titration.
Why do we heat KSCN Fe solution befor titration with EDTA?
We usually heat KSCN Fe solution before titration with EDTA so as to produce crystalline crust forms.
