School Now fill the table with the observations. Sodium chloride Water HCI Acetic acid NaOH NH4OH What is required for the lamp to ignite? What is the difference between substances that conduct electricity and those that do not lead? What is your conclusion about the electrical conductivity in aqueous solutions? The Arrhenius theory was so revolutionary for thought at the time that their teachers have earned him the title of doctor with the lowest possible qualification without reproach him. However, his persistence and his theory as "dissociation of substances on the in aqueous solutions "could explain many phenomena known at the time and slowly gained acceptance in the scientific community. And, in 1903, Arrhenius won the Nobel Prize in Chemistry for Ionic Dissociation Theory. Although the concept of acids and bases for Arrhenius has been importantly, it has limitations. For, Arrhenius, substances behave as acid or base only when they are dissolved in water. And yet, according to Arrhenius substances behave like acid if they bring hydrogen ion, H or behave as if they have the basic hydroxide ion, OH in its composition. Thus, the concept of acid and base, according to Arrhenius not applica- ca the reaction between HCl and ammonia NH as they are not in aqueous solution and ammonia does not present the OH ion. Observe the reaction: HCl + NH NH However, when HCl reacts with is the formation of a white fog which is ammonium chloride, a solid ionic called of salt. Matter and Its Nature

Škola Sada ispunite tablicu s opažanjima. Natrijev klorid Voda HCI Octena kiselina NaOH NH4OH Što je potrebno za svjetiljke zapaliti? Koja je razlika između tvari koje provodi struju i onih koji ne vode? Koji je tvoj zaključak o antistatičnosti u vodenim otopinama? Arrhenius teorija je tako revolucionarno u mislima u vrijeme kada su njihovi učitelji zaradio mu je titulu doktora s najniže moguće kvalifikacije bez njega predbacuju. Međutim, njegova upornost i njegova teorija kao "disocijacija tvari na u vodenim otopinama "moglo objasniti mnoge pojave poznate u vrijeme i polako dobio prihvaćanje u znanstvenoj zajednici. I, 1903, Arrhenius je osvojio Nobelovu nagradu za kemiju za jonske disocijacija teoriju. Iako koncept kiselina i baza za Arrhenius je najvažnije, ona ima ograničenja. Jer, Arrhenius, tvari ponašaju kao kiseline ili baze samo kad su otopljeni u vodi. A ipak, prema Arrhenius tvari ponašaju poput kiseline ako oni donose iona vodika, H ili se ponašaju kao da su osnovni hidroksid iona, OH u svom sastavu. Dakle, koncept kiselina i baza, prema Arrhenius nije aplikacijski . ca reakcije između HCl i amonijaka kao što su oni nisu u vodenoj otopini i amonijak ne predstavlja OH ion Obratite pozornost na reakciju: HCl NH Međutim, kada se HCl reagira s je formiranje bijele magle što je amonijev klorid, čvrste ionski zove soli. materije i njezine prirode
