NCERT Solutions for Class 10 Science Chapter 1: Chemical Reactions and Equations
This chapter introduces students to the language of chemistry - how to write and balance chemical equations. A frequent stumbling block is distinguishing between the different types of chemical reactions: combination, decomposition, displacement, double displacement, and redox reactions. The solutions walk through every NCERT exercise question with balanced equations and explanations of observable changes such as colour change, gas evolution, and precipitate formation, which are also key indicators examiners look for in board answers.
NCERT Solutions for Class 10 Science Chapter 2: Acids, Bases and Salts
Chapter 2 covers the chemical properties of acids and bases, the concept of pH, and the preparation of important salts like sodium hydroxide and baking soda. Students often confuse the properties of acids and bases in aqueous solutions with their behaviour in non-aqueous conditions. The solutions clarify this distinction and explain why indicators like litmus change colour, with detailed answers to all NCERT in-text and exercise questions.
NCERT Solutions for Class 10 Science Chapter 3: Metals and Non-Metals
This chapter deals with the physical and chemical properties of metals and non-metals, the reactivity series, and the extraction of metals from ores. One area where students commonly lose marks is in explaining ionic bond formation using electron transfer diagrams. The NCERT solutions here provide clear, step-by-step explanations of how metals react with oxygen, water, and acids, along with well-structured answers for all exercise questions.
NCERT Solutions for Class 10 Science Chapter 4: Carbon and Its Compounds
Carbon's unique ability to form long chains (catenation) and bonds with multiple elements makes this chapter both fascinating and complex. Students frequently struggle with naming homologous series members and identifying functional groups in organic compounds. The solutions cover all NCERT questions on covalent bonding, saturated and unsaturated hydrocarbons, and the chemical properties of ethanol and ethanoic acid, with particular attention to reaction equations that carry high marks in board exams.
NCERT Solutions for Class 10 Science Chapter 5: Life Processes
Life Processes covers the essential biological functions - nutrition, respiration, transportation, and excretion - in both plants and animals. A common error students make is mixing up the pathway of oxygenated and deoxygenated blood through the heart's chambers. The solutions provide labelled diagram explanations and precise answers for questions on photosynthesis, the human digestive system, and the nephron's role in urine formation, all aligned with CBSE board marking schemes.
NCERT Solutions for Class 10 Science Chapter 6: Control and Coordination
This chapter explains how the nervous system and endocrine system work together to regulate body functions. Students often find it difficult to distinguish between voluntary, involuntary, and reflex actions and to accurately describe the reflex arc pathway. The solutions address all NCERT questions on the human brain's structure, tropic movements in plants, and the role of hormones like adrenaline and thyroxine, with answers structured for maximum marks.
NCERT Solutions for Class 10 Science Chapter 7: How Do Organisms Reproduce?
Reproduction - both asexual and sexual - is the focus of this chapter, covering organisms from Amoeba and Hydra to flowering plants and humans. A point of confusion for many students is explaining why sexual reproduction leads to greater variation than asexual reproduction. The solutions cover fission, budding, vegetative propagation, pollination, fertilisation, and the human reproductive system with clear diagrams and board-ready answers.
NCERT Solutions for Class 10 Science Chapter 8: Heredity
Chapter 8 explores Mendel's laws of inheritance, the concept of dominant and recessive traits, and how sex is determined in humans. Students frequently make errors while constructing Punnett squares, especially for dihybrid crosses, and misinterpret the 3:1 phenotypic ratio. The solutions provide accurate cross diagrams and explain the molecular basis of heredity, including the role of DNA in trait transmission, with answers tailored to CBSE board expectations.
NCERT Solutions for Class 10 Science Chapter 9: Light - Reflection and Refraction
This chapter covers the laws of reflection, the mirror formula, refraction through glass slabs and lenses, and the lens formula. Numericals involving sign conventions are a major source of errors - students often apply the wrong sign to object or image distance when using the New Cartesian convention. The solutions methodically solve every NCERT numerical and conceptual question, clearly showing sign convention application and ray diagram construction for concave and convex mirrors and lenses.
NCERT Solutions for Class 10 Science Chapter 10: The Human Eye and the Colourful World
Chapter 10 explains how the human eye forms images, common defects like myopia and hypermetropia, and atmospheric phenomena such as dispersion, scattering, and the twinkling of stars. Students commonly confuse why the sky appears blue (Rayleigh scattering of shorter wavelengths) with why the sun appears red at sunrise and sunset. The solutions address all NCERT questions with precise scientific explanations and relevant diagrams.
NCERT Solutions for Class 10 Science Chapter 11: Electricity
Electricity is one of the most numerical-heavy chapters in Class 10 Science, covering Ohm's Law, resistance, series and parallel circuits, and the heating effect of electric current. A common mistake is incorrectly applying the formula for equivalent resistance in parallel circuits, leading to wrong answers in multi-step problems. The solutions provide fully worked-out numerical solutions alongside conceptual answers, making it easier to score full marks on both types of questions.
NCERT Solutions for Class 10 Science Chapter 12: Magnetic Effects of Electric Current
This chapter covers the magnetic field due to a current-carrying conductor, Fleming's left-hand and right-hand rules, the electric motor, electromagnetic induction, and the electric generator. Students often mix up Fleming's left-hand rule (for motors) with the right-hand rule (for generators). The solutions clearly explain each rule in context and answer all NCERT questions on solenoids, domestic electric circuits, and the difference between AC and DC.
NCERT Solutions for Class 10 Science Chapter 13: Our Environment
The final chapter examines ecosystems, food chains, food webs, and the impact of human activities on the environment, including ozone layer depletion and waste management. A detail students frequently overlook is explaining why the energy available at each trophic level is only about 10% of the level below - the 10% energy law - which is central to several high-mark board questions. The solutions address all NCERT exercise questions with environmentally accurate and well-structured answers.
How to Use CBSE Class 10 Science NCERT Solutions Effectively for Board Exam Preparation
The most effective way to use these NCERT Solutions for Class 10 Science is to attempt each question independently first, then compare your answer with the solution to identify gaps in your reasoning. For chapters like Electricity and Light, where numericals carry significant weightage, practising the sign convention and formula application repeatedly is essential. EduRev's solutions are structured to reflect the exact marking scheme CBSE follows, so students can use them to self-evaluate answer quality before their board exams.
