Comment on the grading done by the professor in your opinion?

the word “Chill grading” is redefined all together

What was the Attendance Policy?

No DX grades were awarded. However Labs are mandatory to attend unless genuine medical reason is there. the lecture before the labs have no attendance enforced

Pre-Requisites?

None

This Course evaluation comprises of?

written exam and practical exam at the end of the course

each of the lab experiment performed on any any given lab day is also accounted towards grading and carries a mammoth portion towards the grade.

What are the topics covered in the course?

Basic concepts of quantitative analysis, methods of sampling, errors in chemical analysis of data, general theory of neutralisation, redox, precipitation and complexometric titrations. Solubility product and precipitation, organic precipitants and extractants. A brief survey of separation methods: solvent extraction and chromatography.

Inorganic Semi-micro qualitative analysis involving 4 radicals. Volumetric analysis involving redox, precipitation and complexometric titrations. Gravimetric estimation of metals. Analysis of alloys and minerals.

How were the Lectures for this course?

Prof ghosh conducts a pre lab lecture to explain theory but i personally found a rather disconnect between what was being taught and what we actually did on the day of experiment. however it recommend you see some youtube video or brush up the concepts of experiments before hand

How were the Exams for this course?

Exam are quite easy and require presence of mind . no mugging whatsoever will help. its recommend you get a look at past years paper to gauge an idea . For the practical exam you are given either titration or salt analysis on the basis of chit you select. Task is similar to the one done during experiments performed earlier

Any tips for the junta to perform well in the course?

this lab course is pretty chill grading wise and for that matter all chemistry lab courses in sophie year. i would really suggest doing the reaction and observing stuff carefully. don’t just do it for the sake of doing it . Such observational skills will really help in your research career . These labs are there to give you exposure. all the reactions which you are performing have been done multiple times over the past . Just focus on learning aspect of Lab
