Econoburette: Easier way to Conduct Titration

February 14th, 2008

Many a student nightmare originates in chemistry labs. Titration is one of them. It may be a big word but it’s a simple process to detect a solution’s potency. It requires sucking in acid through a pipette (a thin glass tube) to measure it.

A measured amount of a solution of an unknown concentration is added to a known volume of a second solution. There is an indicator to show when the reaction is complete and then the concentration of the unknown solution is calculated. This causes problems because students trying out the experiment end up gulping in the acid.

“When it is swallowed, the mouth becomes dry and it seems that the teeth will chip off. Teachers just ask us to spit out the acid and wash the mouth. I wish there were other ways to carry out the experiment,’ says Aparajita Tiwari, a class 12 student of Delhi Public School, Noida. A student from Kerala, Bright E S, says, “When one takes 10 ml of acid in a 12 ml capacity tube, chances of swallowing it are high.’ Continue reading »
