ENGLISH

Introduction

The course is designed to train students in receptive (listening and reading) as well as productive
and interactive (speaking and writing) skills by incorporating a comprehensive, coherent and integrated
approach that improves the learners' ability to effectively use English language in academic/ workplace
contexts. The shift is from learning about the language to using the language. On successful completion
of the compulsory English language course/s in B.Tech., learners would be confident of appearing for
international language qualification/proficiency tests such as IELTS, TOEFL, or BEC, besides being able
to express themselves clearly in speech and competently handle the writing tasks and verbal ability
component of campus placement tests. Activity based teaching-learning methods would be adopted to
ensure that learners would engage in actual use of language both in the classroom and laboratory
sessions.
Course Objectives
Facilitate effective listening skills for better comprehension of academic lectures and English
spoken by native speakers
Focus on appropriate reading strategies for comprehension of various academic texts and
authentic materials
Help improve speaking skills through participation in activities such as role plays, discussions and
structured talks/oral presentations
Impart effective strategies for good writing and demonstrate the same in summarizing, writing
well organized essays, record and report useful information
Provide knowledge of grammatical structures and vocabulary and encourage their appropriate use
in speech and writing
Learning Outcomes
At the end of the module, the learners will be able to
understand social or transactional dialogues spoken by native speakers of English and identify the
context, topic, and pieces of specific information
ask and answer general questions on familiar topics and introduce oneself/others
employ suitable strategies for skimming and scanning to get the general idea of a text and locate
specific information
recognize paragraph structure and be able to match beginnings/endings/headings with paragraphs
form sentences using proper grammatical structures and correct word forms

5. Determination of Cu+2 using standard hypo solution.
6. Determination of temporary and permanent hardness of water using standard EDTA solution.
7. Determination of Fe+3 by a colorimetric method.
8. Determination of the concentration of acetic acid using sodium hydroxide (pH-metry method).
9. Determination of iso-electric point of amino acids using pH-metry method/conductometric
method.
10. Determination of the concentration of strong acid vs strong base (by conductometric method).
11. Determination of strong acid vs strong base (by potentiometric method).
12. Determination of Mg+2 present in an antacid.
13. Determination of CaCO3 present in an egg shell.
14. Estimation of Vitamin C.
15. Determination of phosphoric content in soft drinks.
16. Adsorption of acetic acid by charcoal.
17. Preparation of nylon-6, 6 and Bakelite (demonstration only).
Of the above experiments at-least 10 assessment experiments should be completed in a semester.
Outcomes: The students entering into the professional course have practically very little exposure to lab
classes. The experiments introduce volumetric analysis; redox titrations with different indicators; EDTA
titrations; then they are exposed to a few instrumental methods of chemical analysis. Thus at the end of
the lab course, the student is exposed to different methods of chemical analysis and use of some
commonly employed instruments. They thus acquire some experimental skills.
