VCD on Common Laboratory Techniques in Analytical Chemistry and Organic Chemistry

The VCDs aiming to provide relevant self-learning materials for year-one Chemistry majored students to learn the basic laborator y techniques encountered in Analytical and Organic Chemistr y laboratories were produced. To enhance teaching and learning, two different presentation approaches - role-playing and experiment demonstration - were adopted in the video. The first part of the video covers basic analytical chemistry techniques such as proper chemical weighing and handling, correct use of volumetric flasks, titration with standardised NaOH and accurate burette reading. The second part involves techniques commonly employed in an Organic Chemistr y laborator y such as simple distillation, general reflux, liquid-liquid extraction, vacuum filtration and thin-layered chromatography.
