What is Over titration?
Over titration occurs when an excess of one solution, known as a titrant, is added to another solution. Titration is done to know the amount of solution to be added to reach neutralization.
direct titration involves the direct and stepwise addition of a standard titrant to the analyte whilst the back titration involves reacting a standard excess titrant wth an analyte solution of an unknown concentration, then reacting the excess (left over) titrant with an analyte of known concentration to determine the concentration of excess titrant.
How do you calculate the concentration of 10mL of a weak acid in a titration where the strong base has a molarity of 0.09994M and the equivalence volume is 21.20mL?
In fact, a back titration is carried out as in a very similar method to an ordinary titration. the only difference is in the context. Consider an unknown acid solution. Then a known amount of excess alkali was added to the solution and made them react. Then the process of finding the amount left from the alkali is known as the back titration.
