Question

reaction of lemon juice on marble pieces​

Answer 1

$\huge\fcolorbox{black}{black}{answer}$

Calcium carbonate, present in marble, reacts to acid by corroding its surface, creating dull spots. Acids corrode marble and leave a discoloured or less shiny spot called an etch mark.

Answer 2

Answer:

This is because marble is made of calcium carbonate and lemon juice is acidic in nature. This acid in lemon reacts with the calcium carbonate in marble and corrode the marble producing carbon dioxide. When lemon juice will fall on marble floor, it will leave dull spots on the floor and leaves the marble textured.
