CBSE Class 9: Science Experiment (SA1) - Test the presence of adulterant metanil yellow in dal (MCQs)

Test the presence of adulterant metanil yellow in dal 

Metanil yellow is a synthetic dye which is not permitted to use as food colour. However it is used extensively in India to give yellow colour to Dal (pulses) and turmeric. Metanil yellow is toxic by nature and it has adverse effects on liver, intestine and brain.

To test the presence of metanil yellow in dal, take the following steps:

1. Take approximately 5 gms of dal in a test tube and add 5 ml of water. 
2. Shake the test tube well. 
3. Add few drops of concentrated hydrochloric acid to the test tube. (This activity should be done in the presence of your school teacher).
4. The appearance of a pink colour in the solution confirms the presence of metanil yellow in dal

(MCQs asked in CBSE examination)

Q1: Metanil yellow changes the colour of solution of dal to
(a) green
(b) pink
(c) blue
(d) dark red

Bed Of Nails - A circus trick
image credits: Jendi's Journal

Q1:  Bhola was impressed by the miracle performed by Baba Bandar Nath when Baba lied down on a bed of nails. The nails did not hurt him. Bhola narrated about this miracle to his friend Rithik. Rithik explained to Bhola that there is no magic or miracle here. Even he can also do the same trick.

(a) Why did Rithik say that there is no 'miracle' in this trick? Why did Baba Bandar Nath did not hurt himself?
(b) Which quality is shown by Rithik here?

Answer:
(a) Rithik is right that there is no miracle here. We know that pressure is defined as force acting per unit area. If you step up on a nail, the entire body weight exerts more pressure because the area of nail tip is very small. In case of bed of nails, the pressure exerted by the weight of the body is distributed among the hundreds or thousands of nails lying close to each other. Thus the net pressure on a nail is very small.
