Worked practice questions

Acids turn blue litmus paper

  1. blue
  2. green
  3. red
  4. grey
Show answer and solution

Correct answer: C. red

1. Litmus is a natural acid base indicator. 2. In an acidic solution it changes from blue to red. 3. Bases do the reverse, turning red litmus blue. _Source: AP/TS SCERT Class 10 Physical Science, "Acids, Bases and Salts"_

Phenolphthalein added to a basic solution turns

  1. blue
  2. grey
  3. white
  4. pink
Show answer and solution

Correct answer: D. pink

1. Phenolphthalein is a synthetic acid base indicator. 2. It stays colourless in acidic or neutral solutions. 3. In a basic solution it turns pink. _Source: AP/TS SCERT Class 10 Physical Science, "Acids, Bases and Salts"_

The gas usually evolved when a dilute acid reacts with a metal is

  1. hydrogen
  2. oxygen
  3. chlorine
  4. nitrogen
Show answer and solution

Correct answer: A. hydrogen

1. A dilute acid reacts with many metals: acid + metal gives salt + hydrogen. 2. The gas burns with a pop sound when a lit splint is brought near. 3. That pop test confirms the gas is hydrogen. _Source: AP/TS SCERT Class 10 Physical Science, "Acids, Bases and Salts"_
