List of CGBSE Chemistry Practicals for Classes XI & XII

The Chhattisgarh Board of Secondary Education, or CGBSE in short, controls the intermediate level of education in the state of Chhattisgarh. You can find the Chhattisgarh board official website right here:  https://cgbse.nic.in . They have built up quite a good practical curriculum, and therefore we are presenting the CGBSE chemistry practical syllabus in this article.

The state of Chhattisgarh is relatively new in the country, and so they had little time to prepare all their educational infrastructure from scratch. That being said, they have done a remarkably good job of it! Chemistry is among the more difficult subjects to digest, yet they have configured the curriculum in such a way that it is well-paced out and with achievable milestones.

The CGBSE high school level is very important for Chhattisgarh students, who are at this point at a transitional phase in their career. Journeying from general education to precise specializations, students need to acquire some very specific skills in this phase. The CGBSE curriculum helps the students to achieve just that.

The syllabus is quite detailed and covers all the skills a higher secondary level student should acquire by the end of class 11 12. This is quite a long syllabus, and for many reasons many schools do not choose to complete it. But if you are looking to pursue a career in the line of chemistry or technology, then you will need all the skills out of this set of experiments and observations. Naturally, this list comes very handy in this case, to chalk out which practicals you have finished and which not.

    • Cations of: lead, copper, arsenic, aluminum, ferric, manganese, nickel, zinc, cobalt, calcium, strontium, barium, magnesium, ammonium
    • Anions: carbonate, sulphide, sulphite, sulphate, nitrite, nitrate, chloride, bromide, iodide, phosphate, chromate, acetate


Students will also have to complete a project and make a report on that. This would include sample collection, laboratory testing, and information collection from various sources, worth 10 periods of work. Some of the projects that the Chhattisgarh board suggests are as follows.

  • Take drinking water samples from various sources and check for bacterial contamination in them by testing for sulphide ions.
  • Observe how water purification is done in various methods.
  • Take various samples of drinking water from different sources, and check for the following: hardness, presence of iron, fluoride, chloride, etc. Figure out why the results are coming that way. 
  • Study how the foaming capacity of various soaps change with the ingredients, and observe the effect of adding sodium carbonate on them.
  • Test out the acidity (pH levels) of extracts of different types of tea leaves.
  • Observe the evaporation rates of different kinds of liquids.
  • Interpret how acids and bases affect the tensile strength of fibers.
  • Analyze the pH levels of different fruit juices and vegetables.
