Question

why should we take dilute solutions

Answer 1

because it reduces some highly reactive elements to be cool

Answer 2

Accurately Diluting Concentrates via DilutionEquation. Determine what you do and don't know. Performing a dilution in chemistry usually means taking a small amount of a solution whose concentration you know, then adding a neutral liquid (like water) to make a new solution with a larger volume but a lower concentration ...
