Volumetric Analysis

Question 1

Titration

Answer 1

• Measure one solution into a conical flask using a pipette
• The other solution is added from the burette until a permanent colour change of an indicator is seen in the conical flask
• A ‘ rough’ titration is carried out first followed by more accurate titrations until concordant titre values are achieved
• Average value of concordant titres is used in calculations

Question 2

What different titrations are used to carry out volumetric analysis

Answer 2

• Standard Titrations
• Complexometric Titrations
• Back Titrations

Question 3

Primary Standard Characteristics

Answer 3

• high state of purity
• stability in air and water
• solubility
• reasonably high formula mass
