Why wait 10-15 seconds after dispensing a volume of titrant before a reading is made?
It takes a little time for all the molecules in the solution to reach equlibrium. For this reason there is a default time period you should wait to take your reading. You can shorten the time a little if your solution is being stirred but just keep it consistent for each reading. Your teacher or lab proctor probably just like 10-15 seconds.
