Kemi
Af Melanie, Michael og Casper
Formålet



Formålet med forsøgene er at vise hvilke stoffer der
        er tungtopløselige/giver bundfald.
Udstyr


  Der blev brugt pipetter til hver enkelte stof.
        Der blev brugt en transparang.
        Der blev brugt et stykke papir.
     Der blev brugt ipod touch til billeder.
    Og der blev selvfølgelig også brugt de
               forskellige stoffer.
Sikkerhed

I disse forsøg har vi brugt en smule
sikkerhed.


                   Vi har haft brugt kitler og sikkerhedsbriller.
Fejlkilder




 Der kan opstå fejl, ved at man kommer til, at bruge
mere af det ene stof end det andet stof. Og det gør, at
man ikke kan se bundfaldet lige så godt, som hvis der
             var lige meget af hvert stof.
Find de tungtopløselig stoffer.

• NaCl -----> Na+ + Cl- & AgNo3 -----> Ag+ + No3-.
  Na+ + Cl- ----->letopløselig. Ag+ + No3- ----->letopløselig.
  Ag+ + Cl- -----> tungtopløselig. Stoffet bliver hvidt og efter et godt stykke tid
  skifter det til lilla.


• Na2Co3 -----> Na2+ + Co3 2- & Mg(No3) -----> Mg2+ + No3-.
  Na2+ + Co3 2- ----->letopløselig. Mg2+ + No3- ----->letopløselig.
  MG2+ + Co3 2- ----->tungtopløselig. Stoffet bliver en grumset farve.


• KI -----> K+ + I- & Pb(No3)2 -----> Pb2+ + No3-.
  K+ + I- ----->letopløselig. Pb2+ + No3- ----->letopløselig.
  Pb2+ + I- ----->tungtopløselig. Måtte vi ikke udfører.
Find de tungtopløselig stoffer.

• K2So4 -----> (K+) + (SO4 2-) & BaCl2 -----> (Ba2+) + (Cl-)
  K+ + SO4 2- ----->letopløselig. Ba2+ + Cl- ----->letopløselig.
  Ba2+ + SO4 2- ----->tungtopløselig. Stoffet bliver hvidt og dog lidt grålig.


• Na2Co3 -----> Na2+ + Co3 2- & BaCl2 -----> (Ba2+) +(Cl-)
  Na2+ + Co3 2- ----->letopløselig. Ba2+ + Cl- ----->letopløselig.
  Ba2+ + Co3 2- ----->tungtopløselig. Stoffet bliver hvidt men dog noget
  gemmemsigtigt i det.


• BaCl2 -----> Ba2+ + Cl- & CuSo4 -----> Cu2+ + SO4 2-.
  Ba2+ + Cl- ----->letopløselig. Cu2+ + SO4 2- ----->letopløselig.
  Ba2+ + SO4 2- ----->tungtopløselig. Stoffet bliver hvidt.
