Question

Observe what happens when lemon juice falls on shahbad tile

Answer 1

  lemon juice reacts with tiles which  are made up of limestone, then we get calcium citrate salt , which should just wipe up with water.

Answer 2

Shahabad tiles are mainly made out of lime stone,which we use in our households.

If we pour some lemon juice on these tiles,a low hizzing sound will be started with the formation of a white powdery substance.

Actually the citric acid present in the labourers reacts with limestone present in the tiles,which forms a type of calcium salt.This salt is easily removable by wiping with clothes.
