Upskilling Science

Upskilling Science (online) is a 15 hours module designed as part of our employability project Lakshya, which aims at bridging the gap between academia and industry by sharpening the subject knowledge and work skills of the students to meet industry requirements. This course will help students to get clear understanding of fundamental concepts of both theory and Practical applications along with basic instrumentation aspects of various machines used in industries. This course is ideal for B.Sc. Chemistry students and anyone with science background who is interested in pursuing their career in QA-QC department of any Chemical or Pharma Industries.

1. Basic Units of Chemistry

This three-part chapter introduces students to the basic concept of chemistry i.e. 'units' based on the natural world, decimal ratios, prefixes for multiples and sub-multiples, and a structure of base and derived units.


Science & Maths 1

1.1 Basic Units of Chemistry Part 1/3

In this chapter we cover definition, base & derived SI units, unit systems, unit prefix conversions & equivalence.


1.2 Basic Units of Chemistry Part 2/3

In this part we discuss units critical to practicing chemistry in academic, research and commercial environment. Units covered in this part include mass, volume, density, temperature, atomic mass, molecular mass & mole concepts.


1.3 Basic Units of Chemistry Part 3/3

This part focusses on more advanced units routinely used in chemistry like molar mass, mass percent of elements, percent by weight, percent by volume, mole fraction, molarity & molality.



2. Normality - Theory & Applications

This chapter is concerned with the basic concept of chemistry 'normality'. This video defines normality as a concept and specifies the formulas used for the calculation of normality of a given solution. It also discusses at length relevant sub-concepts like equivalent weight, acidity, basicity, valence factor & oxidation number, etc. Impact of hydrous and anhydrous nature of chemicals along with acidity and basicity of medium on gram equivalent mass during chemical reaction is also explained. Finally, distinguishing points between molarity and normality are discussed finally concluding with relationship prevalent between these sister concepts.


3. Standardisation - Theory & Applications

This chapter addresses the theory and applications of 'standardisation' and proceeds to engage multitude of relevant topics like primary standard & secondary standard solutions, volumetric analysis/titration, preparation of solutions and standardisation of those acid/base solutions with calculation of normality.


4. Purity - Theory & Applications

This chapter defines 'purity' and specifies normal and titration formula used to calculate purity. This video also contains a theoretical simulated experiment for preparation of HCl solution and determining its purity.


5. Standardisation of HCL & Purity Determination of KOH

This video contained theoretical simulated experiments which include preparation of solutions, their volumetric analysis/ titration for the purpose of standardisation and purity calculation of chemical solutions.


6. pH-Metry - Theory & Applications

This video contains introduction to pH-metry which is a popular instrument used to determine pH (acidity/ basicity) of a given sample. With respect to pH-metry, this video explains principle of operation, practical applications, pH scale, instrumentation of pH meter.

Practical: This video elaborates critical consideration during the pH calibaration and provides step by step instruction to calibrate pH sensor and measure pH of given sample.
