we cannot prepare calcium dulphate by treating marble chips with dilute sulphuric acid .Why

Solution

Dear student,

Marble chips ( $C a C O_{3}$ ) initially reacts with dilute sulphuric acid to form insoluble calcium sulphate, which settles on its exposed surface.
This in turns cut off the dilute sulphuric acid from the marble chips and hence the reaction stops.
