Chemistry Laboratory II

(Practical)

 

CO17: Determine the percentage composition of non interacting systems by viscosity and surface tension method.

CO18: Interpret powder diffraction patterns and operate a pH meter for pH-based experiments.

CO19: Compile and report the results efficiently, and develop communications skills.

CO20: Contribute effectively in course-specific interaction.

Approach in teaching:

Power point presentation, laboratory instructions and demonstrations.

 

 

Learning activities for the students:

Peer learning, hands-on-learning, interpretation of data, record

writing and learning through virtual labs.

 

Conduction of experiments, lab records, viva voce.

 

 

 

Unit I: 

· Surface tension measurements

· Determine the surface tension by (i) drop number (ii) drop weight method.

· Study the variation of surface tension of detergent solutions with concentration.

 

· Viscosity measurement using Ostwald’s viscometer

· Determination of viscosity of aqueous solutions of (i) polymer (ii) ethanol and (iii) sugar at room temperature.

· Study the variation of viscosity of sucrose solution with the concentration of solute.

 

· Indexing of a given powder diffraction pattern of a cubic crystalline system

 

· pH-metry

· Study the effect on pH of addition of HCl/NaOH to solutions of acetic acid, sodium acetate and their mixtures.

· Preparation of buffer solutions of different pH

· Sodium acetate-acetic acid

· Ammonium chloride-ammonium hydroxide

· pH metric titration of

· Strong acid vs strong base

· Weak acid vs strong base

· Determination of dissociation constant of a weak acid.

 

Any other experiment related to prescribed topic can be carried out in the class.
