Urea solution is not strong enough to show change in colour of litmus paper, until and unless we use a highly concentrated solution. Since here we use a small quantity, this option is ruled out. So we make it to react with sodium hydroxide.. This reaction releases ammonia as one of the products which shows a visible change in colour of the litmus paper.
Mam your voice & explanation is amazing
