What are the material should we write in chemistry practical in class 12 according to the cbse?
That's helpful. What about the test tubes? Any specific requirements?
Yes, the test tubes used in the chemistry practical should be made of borosilicate glass and should have a uniform thickness, clear and free from any cracks or defects. They should have round bottoms and should be able to withstand heating and cooling. The CBSE guidelines suggest the use of test tubes with a diameter of 16mm and a length of 150 mm for the practical.
