Unformatted text preview: 6. The centrifuge is used to separate the precipitate from the supernatant solution 7. The main type of reaction in this lab is a double replacement reaction. We see this because precipitate forms. 8. The main way of identifying or confirming the presence of a certain ion is to see if they form a precipitate or a colored liquid is present. The five final products that will confirm the presence of the five ions are: AgCl, Cu 2 [Fe(CN) 6](s) , FeSCN 2+ , K 2 Zn 3 [Fe(CN) 6 ] 2 , Al(OH) 3(s) . 9. The five complex ions include: Ag(Nh 3 ) 2 + (aq) , Al(OH) 4-(aq) , Zn(OH) 4 2 (aq) , Cu(NH 3 ) 4 2+ (aq) , FeSCN 2+ (aq) . 10. Some ions are left out because they are “Spectator ions” and do not take place in the reactions....
