Studying doesn’t have to feel like a slog. The truth is: your brain isn’t built to drag through hours of tedium—it responds best to pattern, reward and rhythm. By shifting how you approach study time, you can turn it from duty into something your brain actually enjoys. Here are five simple, smart ways to do it. Try one today and see how your focus follows. 1. Study in Short Bursts, Not Endless Sessions Forget the idea that you must sit for three hours straight. Cognitive science shows our attention drops significantly after about 25–30 minutes. So use the Pomodoro Technique : study for 25 minutes, take a 5‑minute break; after four rounds, give yourself a longer break (15–20 minutes). That rhythm gives your brain permission to reset—and makes that “next block” easier to start. 2. Turn Learning into a Game The brain loves victory—even tiny ones. Set fun micro‑challenges: finish chapter one in 20 minutes, get 10 questions right in a row, or beat yesterday’s time. E...
In a qualitative analysis of ions like lead, zinc ions and aluminium ions, these ions show similar reactions with dilute sodium hydroxide solution. They produce white precipitates with a few drops of dilute sodium hydroxide solution, which are soluble in excess dilute sodium hydroxide solution. In this article, you will learn how to separate lead ions from a mixture of aluminium ions and zinc ions. Before I go ahead, let me list some reagents that are necessary for the tests: Aqueous ammonia Dilute hydrochloric acid Potassium dichromate solution Potassium iodide solution Step one: separation of zinc ions from the mixture To the solution of the unknown compounds, add a few drops of aqueous ammonia, and the formation of white gelatinous precipitate that dissolves in excess aqueous ammonia removes lead ions and aluminium ions as an insoluble compound in the excess aqueous ammonia while zinc remains in the solution. Step two: separation of aluminium ions fr...
