Basic Principles Of A Chemistry Lab - 1614 Words

Chapter 1 Basic principles Laboratory course is an integral part of chemistry education and accounts for a major percentage of the assessment marks. Chemistry laboratory is a place where the fundamental rules of laboratory techniques which are very important for students at all levels can be learnt. Observations are foreword of experimentation but preconditioned by outline of practical understanding. Design and choice of experimental method may influence the result. The advantage of chemistry laboratory practices will help the students to work precisely and efficiently to get the desired result.

If acids or bases get into your eyes, wash them with water immediately and see a physician as soon as possible. ï  ¶ Always clearout spillages and broken glass wares as it can cause accidents. ï  ¶ Never throw used filter papers, any chemical or broken glass apparatus in the sink or on the floor. Discard all the chemicals as instructed by the instructor and broken glassware in the labelled broken-glass bins. ï  ¶ Clean the glass wares and equipments as well as your work space before leaving the laboratory. ï  ¶ After each laboratory session, hand washing must be done.

These policies mainly include the use of material safety and data sheet (MSDS) and WHMIS. When students first enter the chemistry lab, they are expected to have done WHMIS and to participate in a general tour of the lab. This is done so that students have basic safety training and are aware of where the protection equipment is, such as the eye flush station (National ResearchRead MoreEssay on Lab1: Effect of Ph on Food Preservatives1343 Words   |  6 Pages Lab 1: Effect of pH on sodium benzoate, a food preservative Sheikh M Zakaria Person no. 36295651 TA: Synthia Gratia Date of Submission: 05/29/13 Abstract Sodium Benzoate is a common food preservative used in food products such as jams and jellies, soft drinks, pickles, condiments etc and in tinned products in the market.
