How To Prepare Original Solution | Labkafe
Last week we discussed the Salt Analysis experiment in chemistry lab class 12 practicals. While talking about performing various tests on the original solution or water extract of the salts, we realized that not everybody can be savvy about how to make the original solutions of salts, or, as they are also called, stock solutions. Hence, we…
