Why potassium thiocyanate is added in redox iodometric titration of copper sulphate?
Cu2I2 is precipitates in light pink colour due to adsorption of I2 and the precipitate releases I2 very slowly. Therefore very small amount of potassium thiocyanate is added towards the end point which helps to displace the adsorbed I2 quickly by combining with Cu2I2 to form CuSCN which has less tendency to adsorb I2.
How do you determine the pka value of naphthalene?
Use a method called titration, where a known concentration of either a strong acid (to measure a weak base) or a strong base (to measure a weak acid) is slowly added to a solution of the unknown compound. By measuring the pH of the solution as you do the titration, and by measuring the volume of the known solution that you added to the unknown, you can determine the pKa of the unknown compound.For complete instructions on how a titration is performed, see the Web Links to the left of this answer.how can i determine pka value if pH is given?

How can prevent splattering when flaming a loop which has just used to transfer a culture?
you should drawn the loop slowly from the cooler to the hotter part of flame.Heat from the base of the wire first and slowly move towards the loop's tip. Heat the wire until it is red-hot.
What is the precaution steps for titration?
Ensure the burette is vertical Titrate slowly when reaching the end point
Why titration of weak acids and weak bases are not done?
It is difficult to determine the end point of such a titration, because the titration produces a buffer solution that changes its pH very slowly at the end point, in contrast to reaction between a strong acid and strong base.
What are the precautions in titration?
The precautions in titration are as follows: make sure the acid is in a burette, and the alkali in a flask. Open the tap slowly to avoid dropping acid. Take the reading carefully, and observe the color change carefully.

How do you determine the end point from titration in acid base titration process?
it depends on the indicator used, i.e. phenolphthalein is the most popular. this is colourless in acid, purple in base, very identifiable. Keep actively swirling and when it is expected to turn (figured from a rough titration beforehand) add very slowly dropwise untill the colour turns.
Why titrations of weak acids and weak bases are not done?
It is difficult to determine the end point of such a titration, because the titration produces a buffer solution that changes its pH very slowly at the end point, in contrast to reaction between a strong acid and strong base.
What is acid neutral?
alkalis / bases neutralise acids, a method in which to do this is titration where the acid is slowly added to the alkali through a burette until the mixture is neutral
Does fade mean to drift?
Fade: means to lessen or slowly go away. Drift: means to slowly or carried away by air or water. Answer- Yes
