2. Titration
A titration is a technique where a solution of known
concentration is used to determine the concentration of an
unknown solution.
 A solution whose concentration is known is called as Standard
Solution.
 The solution whose concentration is unknown is called as
Sample Solution.

3. Principle of Titration
M1V1=M2V2
where
M1 Molarity of Unknown Solution
V1 Volume of Unknown Solution
M2 Molarity of Known Solution
V2 Volume of Known Solution

4. Acid Base Titration
An acid–base titration is a method of quantitative
analysis for determining the concentration of
an acid or base by exactly neutralizing it with a standard
solution of base or acid having known concentration.
Instruements
 Burette
 Conical Flask
 Magnetic Stirrer
 Pipette
 Funnel

6. NaOH + HCL NaCl + H2O
Procedure:-
• If the solution of NaOH is known. While the solution of
HCl is unknown.
• Firstly we take the solution of HCl in a Flask by the help of
pipette so that we know its volume.
• Then we add an indicator in the solution of HCl.
• After this we add a solution of NaOH in a burete through
a funnel and calculate its initial volume.
• Then we slowly open the tap of the burete and start
titration and allows the NaOH solution to fall in HCl
solution.

7. • Magnetic stirrer is used to improve the mixing of NaOH
solution in HCl solution contatining indicator
• After some time end point occurs at which HCl solution
starts changing its colour permanently.
• This end point is also called as Neutralization Point.
• At end point we stop titration by closing the tap of the
burete and calculate the final volume of NaOH solution
present in the burete.
Volume of NaOH= V1 = Initial Volume – Final Volume
= 50 – 42
V1 = 8ml

8. Calculations
M1V1=M2V2
M1x10 = 0.1x8
M1 = 0.1x8
10
M1 = 0.08 M
