In question 2c why do we use distillation of addition instead of heating under reflux since there is no indication that the oxidation is intended to be complete?

[@deenamirza322]

How's the temperature in b(ii) 19.7°C? How do we know the starting temperature??

[@wimsy7767]

check top left on the graph

[@deenamirza322]

@@wimsy7767 oh yeahhhh thank you! Didn't see that point.

[@drhanaaassil-chemistryteac9433]

From extrapolation of the graph to time zero (10.7) to the highest temperature plotted in the curve (19.7)

in 3cii how did u know that 15.85 cm3 was silver nitrate's volume?

[@yamanmasad477]

[@nusratzaman8299]

[@birdie7344]

7:51 how would we know if the value wasnt consistent?

[@dude_mude3366]

THANK U U UU U U. Ur videos are 💯

[@dickmercs3852]

You have the moles of AgNO3 in the mean titre. Why do you say that all the silver ions react with the Cl- ions when some of them Ag+ ions also react with chromate ions?
