School The Lewis theory is broader as it does not depend on aqueous or other solvent. It covers the Arrhenius theory and BrönstedLowry. The Arrhenius theory aqueous medium depends on the presence of the acid H ions and OH ions in the base. The theory Bronsted-Lowry contains substances which are not in aqueous media, but still relies on the presence of protons H Therefore, each of the theories that seek to explain the behavior of acidic and basic substances has its value, since each is appropriate to the given situation. And then, you already know how to master the "Dragon" in your stomach? Then we will know even more about ácidobase that you will surely find a way to master this "dragãooo"! Could we replace the lemon or vinegar hydrochloric acid to flavor a salad? The citric acid of lemon vinegar and acetic acid are weaker acids than hydrochloric acid, so we can use them as seasoning. ACTIVITY Develop a research on the topic: "poisoning caused by household products." After expose to colleagues through posters, photos, banners, etc., The necessary precautions to prevent this type of poisoning. Electronegativity is the tendency of an atom has to attract electrons to itself. According to Lewis theory, the strength of an acid is directly linked electronegativity of the elements. Let's compare ammonia (NH and water (H The electronegativity of nitrogen is lower than that of oxygen (see the periodic table). Therefore nitrogen is easier to get the pair of electrons that oxygen. Therefore, ammonia (NH behaves more basic than water (H

Škola Lewis teorija je šira, jer ne ovisi o vodena ili drugih otapala. Ona pokriva Arrhenius teoriju i BrönstedLowry. Vodena Arrhenius teoriju srednje ovisi o prisutnosti kiseline H ioni i OH iona u bazu. Teorija Bronsted-Lowry sadrži tvari koje nisu u vodenim medijima, ali još uvijek oslanja na prisutnost protona H Dakle, svaki od teorija koje nastoje objasniti ponašanje kiselom i baznom tvari ima svoju vrijednost, jer svaki je prikladno u datoj situaciji. I onda, ti već znaš kako svladati "Zmaj" u trbuhu? Tada ćemo znati još više o ácidobase da ćete zasigurno pronaći način da se ovlada "dragãooo"! Možemo li zamijeniti limun ili ocat solne kiseline na okus salatu? Limunska kiselina od limuna octa i octene kiseline su slabija kiselina od klorovodične kiseline, tako da ih možete koristiti kao začin. AKTIVNOST Razviti istraživanje na temu: "trovanje uzrokovano proizvodima za kućanstvo." Nakon izložiti kolegama putem plakata, fotografija, bannera, itd., potrebne mjere opreza kako bi se spriječilo ovu vrstu trovanja. Elektronegativnost je tendencija atoma mora privući elektrone k sebi. Prema teoriji Lewis, Jakost kiseline izravno povezan elektronegativnost elemenata. Neka je usporediti amonijak (NH i vode (H Elektronegativnost dušika je manja od kisika (vidi periodični). Stoga dušik je lakše dobiti par elektrona koji kisika. Stoga, amonijaka (NH ponaša više osnovnih od vode (H materije i njezine prirode
