Column I	Column II
(i) Soap chips	(b) small broken pieces of soap formed from melted soaps
(ii) Soap granules	(a) dried miniature soap bubbles
(iii) Soap powder	(d) soap powder + builders like \[\ce{Na2CO3}\] and \[\ce{Na3PO4}\]
(iv) Scouring soap	(c) soap powder + abrasives + builders \[\ce{(Na2CO3,Na3PO4)}\]

Explanation:

(i) Soap chips are made by running a thin sheet of melted soap into a cool cylinder and scraping off the soaps in small broken pieces.

(ii) Soap granules are dried miniature soap bubbles.

(iii) Soap powders contain soap powder and builders like sodium carbonate and trisodium phosphate. Builders make the soap act more rapidly.
