Chemistry Lab Practical
We at DPS, Nashik not only believe in teaching the conceptual knowledge of a particular subject but also showing them certain practicals which are conducted in the respective laboratories of the school which enables them the better understanding of the Science as a subject. Practicals also change the monotonous way of teaching and make them understand things in a better way. Students were taught firstly the basic difference of Natural and Synthetic indicators used in labs. Natural indicators like turmeric paste and China rose (hibiscus flower) solution was asked to make by themselves which developed curiosity among them. Synthetic indicators like Phenolphthalein and Methly Orange were used. The chemicals used were Hydrochloric acid (HCl) and Sodium Hydroxide (NaOH), which showed various colour change with each indicator used.
This activity was conducted for the better understanding of students and easy way to learn various colour changes using different indicators. They were also shown the Neutralization reaction, which they named it as “Magic reaction”, as the reaction involved the change of solution from pink colour to colourless on addition of an acid to it.
