Why is a titration performed?
To find the unknown concentration of a sample by using a reagent with a known concentration. ( IE; molarity )
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?
Titration is a method for determining the concentration of a substance in solution. It is performed by by adding to the solution a reagent of known concentration in carefully measured amounts until a visible (eg colour change) reaction happens. Then as the concentration of the reagent is know and the volume of the reactant is known, one can calculate the concentration of the reactant present in the solution.
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.
Use a method called titration, where a known concentration of either a strong acid (to measure a weak base) or a strong base (to measure a weak acid) is slowly added to a solution of the unknown compound. By measuring the pH of the solution as you do the titration, and by measuring the volume of the known solution that you added to the unknown, you can determine the pKa of the unknown compound. For…
