Question

Consider the following statements and choose the incorrect one. i) The red cabbage extract is also a natural indicator. ii) The red cabbage extract turns red on adding acidic solution and turns green on adding basic solution. iii) Sodium hydroxide solution turns red litmus to blue, so sodium hydroxide solution is basic in nature. iv) Methyl orange indicator gives yellow colour in acid solution and red colour in basic solution.​

Answer 1

Answer:

The incorrect one is ii)

Answer 2

The incorrect statement is iv) Methyl orange indicator gives yellow colour in acid solution and red colour in basic solution.​

• The statement written is incorrect as the solutions have been changed. They are opposite to what is mentioned.
• The indicator gives yellow colour in a basic solution.
• Whereas, the same indicator gives the red colour in an acidic medium
• As a result, the proper sentence is: Methyl orange indicator produces yellow in basic solutions and red in acidic solutions. ​
