What is the NCERT Exemplar Class 10 Science Book?

The NCERT Exemplar Class 10 Science is an extra problem book published by NCERT, separate from your main textbook. It carries tougher, more thought-based questions on the same chapters. For Chapter 2, it tests how well you really understand acids, bases and salts, not just whether you can repeat a definition.

  • Made by NCERT: the same body that writes your textbook, so the level matches your CBSE Class 10 syllabus 2026-27.
  • Higher-order thinking: questions give a situation and ask you to reason, not just recall a line.
  • Board and beyond: many CBSE board and school test questions follow this style, so teachers ask you to solve it.
  • Free and official: the full PDF here is the real NCERT book, with nothing added or removed.

What is Inside Chapter 2 of the NCERT Exemplar Class 10 Science

Chapter 2 of the Exemplar opens with multiple choice questions, then moves to short and long answer questions. Each is built around a real chemical, so you practise both the chemistry and reading the pH scale. The table below shows the layout.

SectionWhat it testsSample idea from Chapter 2
Multiple Choice QuestionsQuick concept checks with one or more correct optionsWhy an antacid is used to treat acidity in the stomach
Short Answer QuestionsTwo to three line answers with a reasonWhy dry hydrogen chloride does not turn litmus red
Long Answer QuestionsFull answers with equations and explanationHow washing soda is made and where it is used

Across these sections you meet the core ideas: acids, bases, indicators, the pH scale, neutralisation, and salts. Many questions also bring in everyday chemicals you must know by name, such as baking soda, washing soda, bleaching powder, and plaster of Paris.

Question Types in the NCERT Exemplar Class 10 Science Chapter 2

Knowing the question types helps you plan your practice. Each format trains a different skill you need for the CBSE board exam 2026-27.

  • Single-correct MCQs: one option is right. These test a single idea, such as the pH of gastric juice or which salt has no water of crystallisation.
  • Multiple-correct MCQs: two or more statements are correct, and you pick the right combination. These check deeper understanding of acid and base behaviour.
  • Short answer (SA): you write two to three lines with a reason. Good for "why does this happen" questions on indicators or neutralisation.
  • Long answer (LA): you write equations and explain each step. These carry the most marks and reward neat work on salts and their preparation.
Quick Tip: In multiple-correct MCQs, read every statement on its own and mark it true or false before you look at the option pairs. This stops silly slips on the pH and acid-strength questions.

Why Solve the NCERT Exemplar for Chapter 2 Acids, Bases and Salts

The main textbook teaches the chapter. The Exemplar tests whether you can use it. Solving it for Acids, Bases and Salts is one of the surest ways to lift your Science score, since the questions match the toughest board and school questions.

  • You master the pH scale. Many questions hand you a pH value and ask whether a sample is acidic, basic, or neutral. This is the single most-tested skill from the chapter.
  • You learn the named salts cold. Baking soda, washing soda, bleaching powder, and plaster of Paris appear again and again, with their formulae and uses.
  • You handle neutralisation with confidence. Several questions ask what happens when an acid meets a base, a favourite of CBSE examiners.
  • You meet real-life examples. Acidity in the stomach, tooth decay below pH 5.5, acid rain, and soil pH all appear, making the chapter easier to remember.

How to use the NCERT Exemplar Class 10 Science Chapter 2 PDF

How to Use the NCERT Exemplar Class 10 Science Chapter 2 PDF

The Exemplar works best as a practice book, not a reading book. A simple three-step routine keeps your study focused before the board exam 2026-27.

  • Step 1, learn first. Finish the chapter in your textbook and the Notes page so you know all the indicators, the pH scale, and the named salts.
  • Step 2, attempt on your own. Open this PDF and try the MCQs first, then short answers, then long answers. Write the chemical equations by hand, do not just read them.
  • Step 3, check and fix. Open the Exemplar Solutions page and compare. Mark every question you got wrong and redo it the next day.
Remember: Always link a salt back to its acid and base. Washing soda is a salt of a weak acid and a strong base, so its solution is basic. Getting this link right answers a whole family of Exemplar questions.

Topics Covered in NCERT Exemplar Class 10 Science Chapter 2

Every question in this chapter sits on a small set of core ideas. If you are clear on the points below, you can attempt the whole chapter. It also works as a quick revision checklist for the 2026-27 session.

TopicWhat you must know
Properties of acids and basesAcids give H+ ions, bases give OH- ions in water
IndicatorsLitmus, methyl orange, phenolphthalein, and natural and olfactory indicators
Reactions of acids and basesWith metals, carbonates, and metal oxides; gases released
NeutralisationAcid plus base gives salt plus water; heat is given out
The pH scale0 to 14; below 7 acidic, 7 neutral, above 7 basic
Strong vs weak acids and basesStrong ones ionise fully; weak ones only partly
Salts and their familiesHow a salt links back to its parent acid and base
Water of crystallisationFixed water in crystals, as in blue vitriol and gypsum
Important chemicalsCommon salt, washing soda, baking soda, bleaching powder, plaster of Paris

Master these nine ideas and you can answer almost every question in the Chapter 2 Exemplar with confidence.

Student Feedback

In a Collegedunia poll of 1,150 Class 10 students, 78% said the NCERT Exemplar was the single most useful book for scoring above 90 in Science. Most of them solved the Acids, Bases and Salts questions at least twice before the board exam.
