While studying the saponification reaction what do you observe when you mix an equal amount of colourless vegetable oil and 20% aqueous solution of NaOH in a beaker
a. the colour of mixture has become dark brown
B. A brisk effervescence is taking place
C. the outer surface of the beaker has become hot
d. the outer surface of the beaker has become cold​
