Learn Solutions: solute, solvent, concentration
Under the CBSE Class 9 Science chapter "Is Matter Around Us Pure," we explore the fundamental nature of mixtures. When you mix sugar into water and it completely dissolves, you are creating a homogeneous mixture known as a solution. In simple terms, a solution is a perfectly uniform mixture of two or more substances, where the composition and properties remain the same throughout the entire volume. Everyday examples like lemonade, soda water, or even the air we breathe are all classic examples of solutions that exist in various states of matter.
Every solution is fundamentally made up of two distinct components: a solute and a solvent. The solute is the substance that gets dissolved and is usually present in a lesser quantity (like sugar crystals), while the solvent is the medium that dissolves the solute and is present in a larger quantity (like water). A critical concept for this chapter is the concentration of a solution, which measures exactly how much solute is present in a given amount of solution. Mathematically, it is frequently expressed as a mass percentage using the formula: Concentration = (Mass of solute / Mass of solution) × 100. A common mathematical rule you must remember is that the total mass of the solution is the sum of both the solute and the solvent combined.
The infographic above visually breaks down these components and formulas for complete clarity. On the left side, you can see a beaker where the lesser-quantity solute (represented by the red crystals) is being added into the larger-quantity solvent (the blue liquid) to formulate a complete solution. On the right, the diagram clearly outlines the mass percentage formula for concentration. In your CBSE Class 9 Science exams, you will frequently encounter numerical problems asking you to calculate concentration. The most common mistake students make is substituting only the mass of the solvent as the denominator. As highlighted in the yellow warning box, you must always add the mass of the solvent and the mass of the solute together to find the true total mass of the solution before executing the final calculation.
Mastering numerical problems on mixtures, concentrations, and solutions can sometimes feel overwhelming.

I have been taking classes from Gulsaz Ma'am since last one year for Physics, Chemistry and Biology for grade 9 (IGCSE). She is an exceptional teacher who has made a significant impact on my understanding of complex concepts. My marks have significantly improved as well. Her patience, clarity, and dedication have helped me grasp difficult topics with ease. The way she breaks down complex problems into manageable parts is truly impressive. Highly recommended for anyone struggling with science!
Teaching since last 20 years
Amit ji is a fantastic teacher. My daughter is very happy with her studies. He is exactly what she needed, a teacher with deep understanding of his subject and a very good communicator. If there is one gripe that I may mention, it's time. We would love to have more classes to cover Physics, but he is completely booked for his time. I would highly recommend him. Thank you.
I gained extensive experience in delivering high-quality education following the CBSE/ICSE curriculum. My key responsibilities included: Classroom Teaching: Effectively taught Mathematics, Physics and Chemistry to students of classes IX, ensuring alignment with the CBSE/ ICSE syllabus and fostering a deep understanding of key concepts. Curriculum Planning: Designed and implemented lesson plans that adhered to the CBSE guidelines, ensuring comprehensive coverage of topics while keeping in mind the varying learning needs of students. Student Assessment: Created and administered tests, quizzes, and assignments in accordance with the CBSE exam pattern. Monitored student performance and provided constructive feedback to facilitate continuous improvement. Interactive Learning: Encouraged an interactive classroom environment, integrating various teaching aids such as multimedia presentations, hands-on activities, and group discussions to enhance student engagement and understanding. Preparation for Board Exams: Provided focused support for students appearing for their CBSE/ICSE board exams by conducting regular revision sessions, mock tests, and personalized guidance to help them excel. Parental Communication: Maintained regular communication with parents regarding student progress, attendance, and overall development. Organized parent-teacher meetings to ensure a collaborative approach to student growth. Co-curricular Involvement: Actively participated in school events, projects, and extracurricular activities, fostering holistic development among students. Professional Development: Engaged in continuous professional development through workshops and CBSE training programs to stay updated with the latest educational practices and policies.
I teach Math and Science to 8th-12th standard students and have been teaching for more than 10 years. Batch of 2 Students: I conduct these small batches with a pair of students of the same class and the education board (I cover all popular boards CBSE, ICSE, IGCSE etc.). Works for those students/parents who are looking for individual attention for their kids but still want it to be a little affordable. *3 classes per week (So 12 a month) *Maths and Science (Also English Grammar and Literature) *Fee Rs. 4500/- per month/12 classes. Batch of 6 Students: I conduct these small batches with 5-6 students of the same class and the education board (I cover all popular boards CBSE, ICSE, IGCSE etc.). *4 classes per week (So 16 a month) *Maths and Science *Fee Rs. 4000/- per month/16 classes. I will start the classes immediately once the first kid enrolls. ------------------------------------------------------------------------------- Individual/Private/One-to-One classes: I conduct these one to one classes for those students willing to have one to one setup (I cover all popular boards CBSE, ICSE, IGCSE etc.). *3 classes per week (So 12 a month) *Maths and Science (Also English Grammar and Literature) *Fee Rs. 7000/- per month/12 classes. ------------------------------------------------------------------------------- I took classes and batches in different institutions.
The teacher is very good. He understands the students strength and weakness and decides the pace of learning. He also tries to make the student comfortable and at ease with his/her capacity and then works on the child. It is not just Math he works on but the child's confidence and comfort with the subject. Highly recommended.
I am a teacher and I have been teaching for the past 20 years. l am presently teaching in a school. l have done MSc in Maths and have taught many students.
Thanks Ma'am for supporting Anvi in the subject. She has been getting more comfortable and relaxed with the theory and concepts in mathematics. Her fear is waning away and she shows an increased interest in the subject. I will definitely recommend you to all prospective parents. Thanks again!
