Syrer
Organiske og uorganiske syrer velegnet til en bred vifte af laboratorieapplikationer. Produkterne er tilgængelige i fast og flydende form og i forskellige pH-værdier, mængder, reagenskvaliteter og renheder.
Syrer er defineret som stoffer, der har en sur smag, en lav pH (< 7), og få lakmuspapir til at blive rødt. De reagerer også med baser (giver vand og ioniske forbindelser kaldet salte) og producerer brintgas, når det bruges til at opløse metaller som zink og jern.
Kemisk er en syre et molekyle eller en ion, der fungerer som en proton- eller hydrogeniondonor (Br nsted-øLowry-syre) i en ikke-vandig opløsning. I vand danner syrer hydroniumioner (H 3 O + ).
En syre er alternativt defineret som et molekyle eller ion, der accepterer et elektronpar (Lewis-syre). Et eksempel er trifluorboran, som har et boratom, der er i stand til at acceptere et elektronpar fra ammoniak (NH3) for at danne NH3-BF3.
Almindelige uorganiske syrer omfatter saltsyre, svovlsyre, salpetersyre og phosphorsyre. Almindelige organiske syrer omfatter eddikesyre, benzoesyre, citronsyre og mælkesyre.
I laboratoriet bruges syrer som reagenser eller katalysatorer i mange typer kemiske reaktioner.
Stærke syrer, såsom svovlsyre og saltsyre, er stærkt ætsende og har omfattende kommercielle anvendelser.
- Svovlsyre bruges til at behandle olie og mineraler og til at fremstille andre kemikalier som salpetersyre
- Saltsyre bruges til at sylte stål og andre metaller
- Nogle syrer bruges som neutralisatorer til fremstilling af salte; for eksempel fremstilles ammoniumnitrat ved omsætning af salpetersyre med ammoniak
- Mange syrer bruges også i fødevare- og drikkevareindustrien Har du
