Microscale Experiments in Chemistry –
The Need of the New Millenium

3. Microscale Inorganic Qualitative Analysis and New Methods of Titrations for Introduction at All Levels in Chemistry Laboratories

Shriniwas L Kelkar, Dilip D Dhavale and Prabodh G Pol

 


Shriniwas L Kelkar is a Reader in Organic Chemistry at University of Pune. After an active research career and publishing work on heterocyclic chemistry, he is now devoting his entire time and attention to propagate the small-scale experiments. On demand, he is available to conduct workshops for training teachers on microscale techniques.

Dilip D Dhavale is a Reader in Organic Chemistry at University of Pune. He is pursuing his research career in carbohydrate chemistry. He had been associated with popularizing microscale chemistry from its inception in India.

P G Pol is a Reader in Chemistry at Fergusson College, Pune. He is an author of several reference books for undergraduate classes. He is also available to conduct workshops to train teachers in inorganic microscale experiments.

In the earlier articles we described some experiments which can be carried out in an organic laboratory. Inorganic qualitative analysis constitutes a major bulk in the syllabi of chemistry in academic programmes all over the country. Substantial amounts of inorganic chemicals, reagents and toxic gases like hydrogen sulfide (H2S) are used during the experiments. The fumes of acids and smell of gases evolved or used during chemical reactions had always been a threat to the environment of all laboratories. The conventional method of qualitative analysis prescribes the use of about 0.2 g chemical for every test of the qualitative analysis. This seems to be out of date in the present context and needs a drastic revision.
