Take into consideration the solubiltiy.
1) tell if Organic or aqueous for each
Sudan blue with (1M HCL, water, and 1M NaOH)
Sudan Orange 1M HCL, water, and 1M NaOH
Congo Red 1M HCL, water, and 1M NaOH
Would it take 1M HCL, water , or 1M NaOh to seperate the three dyes on a seperate funnel?
Homework Answers
Sudan blue soluble in 1M HCl, it is organic.
Sudan orrange slightly soluble in water, highly soluble in NaOH solution, so it is aqueous.
Congo Red slightly soluble 10mg/ml in water, highly soluble in 1M HCl, so it is aqueous.
so based on above results we can seperate theree by seperate funnel, first we take 1M HCl and organic solvent, sudan orrange goes to organic layer remaining two in 1M HCl solution. now take water and organic solution Sudan blue goes to organic solution Congored stay in water.

LAB DESCRIPTION: In aqueous solutions the Ni2+ cation forms a complex ion with 6 H2O ligands. The formula of this complex ion is: Ni(H2O)62+. When this complex ion is mixed with aqueous NH3 a reaction occurs where some of the H2O ligands are displaced with NH3 ligands. But how many of the H2O are displaced by NH3? In this experiment you will mix nickel(II) sulfate and aqueous ammonia to synthesize a compound containing a complex ion whose formula is Ni(H2O)6-x(NH3)x2+,...
