A short, practical example (approach, not verbatim solution)

Final take Viraf J. Dalal’s Class 10 Chemistry Textbook Solutions (2021) are a solid study companion: structured, exam-aware, and student-friendly. Used actively—attempt first, consult second—they become powerful tools for mastering Class 10 chemistry rather than mere answer sheets.

The Simplified ICSE Chemistry textbook by Dr. Viraf J. Dalal is a widely used resource for Class 10 students preparing for the ICSE board examinations. The 2021 edition and subsequent versions for the 2021-2022 examination cycle provide comprehensive coverage of the prescribed syllabus. Chapter List & Key Topics

The textbook is typically organized into nine major chapters, each focusing on core chemical principles and their applications:

Chapter 1: Periodic Table – Focuses on periodic properties (atomic size, ionization energy, electron affinity, electronegativity) and their variations across periods and groups.

Chapter 2: Chemical Bonding – Covers electrovalent (ionic), covalent, and coordinate bonding, including Lewis structures for molecules like NH3cap N cap H sub 3

Chapter 3: Acids, Bases, and Salts – Includes classification, properties, and methods of salt preparation.

Chapter 4: Analytical Chemistry – Details the use of ammonium and sodium hydroxide to identify cations through color changes and precipitates.

Chapter 5: Mole Concept and Stoichiometry – Explains Gay-Lussac’s Law, Avogadro’s Law, and calculations for empirical and molecular formulas. Focus: Identification of cations and anions

Chapter 6: Electrolysis – Covers the mechanism of electrolysis, electrochemical series, and applications like electroplating.

Chapter 7: Metallurgy – Focuses on the extraction of metals (like Aluminum) from their ores and the study of alloys.

Chapter 8: Study of Compounds – In-depth study of Hydrogen Chloride, Ammonia, Nitric Acid, and Sulphuric Acid.

Chapter 9: Organic Chemistry – Introduces hydrocarbons (alkanes, alkenes, alkynes), nomenclature (IUPAC), and functional groups.

Chapter 10: Practical Chemistry – Focuses on laboratory techniques and chemical tests. Where to Find Solutions

Solutions for Class 10 Viraf J Dalal Simplified ICSE Chemistry

Here’s a critical/investigative piece about Viraf J. Dalal’s ICSE Chemistry Class 10 textbook solutions (2021 edition).

The Pitfall: Mixing up the laboratory preparations (Kipp's waste for HCl vs. Haber's process for Ammonia). The Solution Strategy: The Challenge: This is the make-or-break chapter

Key Topics: Preparation of HCl gas (Kipp’s waste, laboratory method), fountain experiment, properties of HCl, aqua regia.

Typical Solutions Include:

Let’s test a typical question from the 2021 edition of Chapter 5: Mole Concept.

Question: Calculate the number of molecules in 11.2 liters of CO2 gas at STP.

As per the Viraf J Dalal 2021 Solution:

Step 1: Recall the molar volume concept.
1 mole of any gas at STP occupies 22.4 L and contains (6.022 \times 10^23) molecules.

Step 2: Find moles of CO2.
( \textMoles = \frac\textGiven Volume\textMolar Volume = \frac11.222.4 = 0.5 \text moles)

Step 3: Find number of molecules.
( \textNumber of molecules = \textMoles \times \textAvogadro's Number )
( = 0.5 \times 6.022 \times 10^23 = 3.011 \times 10^23 \text molecules)

Final Answer: (3.011 \times 10^23) molecules of CO2.
