We have our exams too...we can't really afford to spend that much time here now

if the conc is higher, more no of drops will be required to react with solution.

e.g a solution with 5mol/dm3 requires 2 drops to complete the reaction...a solution of 10mol/dm3 will definitely require more no of drops...

gettin it...it's more of stoichio
