The primary agenda in learning a subject like chemistry ought to be that of understanding how matter behaves. Rote learning alone cannot aid one in meeting those ends, especially considering the inherent physical nature of the subject. This rationale has prompted a change in the curriculum of CBSE Class 12 chemistry. The emphasis now lies on ensuring that students understand how chemistry truly works, beyond facts written in textbooks.
At Aakash, we assist an array of students every year in learning and visualising chemical reactions by virtue of formulas. Through this guide, you’ll be able to access all of them in one place and thrive in your exams.
Importance of The Chemistry Formula Sheet
Chemical formulas are the puzzle pieces that make up the complete jigsaw of chemistry as a physical science.
A formula sheet is a consolidated form of many such pieces.
- Acts as a one-stop resource for learning
- Encourages learning through visualisation
- Aids quick revision sessions before exams like JEE, CUET, etc.
- Aids preparation for CBSE Class 12 chemistry MCQs and full-length mock tests
- Makes memorisation easier & less stressful
- Helps optimise time before exams
Students can choose to treat formula sheets as a to-do list as well. Practising detailed conceptual breakdowns of chemical equations by referring to a chemistry formula sheet helps commit them to memory.

CBSE Class 12 Chemistry Formula Sheet: How To Make The Most of It
Ask any overachieving peer, and they’ll tell you how strategically they incorporate chemical formula sheets into lesson and revision plans to elevate their score.
A few points to remember when doing so:
- Personalise your formula sheets through annotations and concept details
- Create colour-coded flashcards based on each topic to aid memorisation
- Note down multiple applications of each formula and visualise reactions
- Download CBSE Chemistry Class 12 PYQs and use the chemistry formula sheet while solving numerical problems
- Use the Feynman technique and pretend to teach formula concepts to a classroom
- Study with your peers and test each other
It’s important to remember that these important chemistry formulas are valuable resources for, specifically, those students who have a clear understanding of concepts.
If loopholes persist in your understanding of core concepts in physical, inorganic and organic chemistry, those need to be tackled promptly.
- Re-learn concepts with a beginner’s approach
- Visualise how atoms, elements, and molecules act
- Focus on each term, including minor energy shifts, and ensure clarity
- Along with memorisation, practice forecasting possible chemical outcomes
In-depth comprehension of concepts imbues you with confidence and exam-readiness. Thereon, recollecting important chemistry formulas becomes easier.
