H2SO4 and Al2(CO3)3 titration
H2SO4 + Al2(CO3)3 is a type of acid-base titration. The end point of titration is the point at which there is a change in the colour of the indicator.
Apparatus used:
Burette, burette stand, conical flask, pipette, beaker, funnel
Indicator
Indicator used is methyl orange.
Procedure:
- Fill the burette with 25ml standardized solution of Al2(CO3)3 and note the initial reading.
- Take known concentration of H2SO4 in the burette.
- Take 10 ml of Al2(CO3)3 solution in a conical flask concentration is not known. Add 2-3 drops of methyl orange to its solution.
- Start titrating by adding dropwise H2SO4 to Al2(CO3)3 solution
- The point at which the colour of methyl orange changes to yellow is the end point of titration.
- Repeat the steps to get the concordant readings.
- Initially the solution is yellow as the pH is high. But as acid is added the pH decreases and the colour changes to red. That is the end point of titration.
