Question

EIS dither TiP us Since they are both alkatine earth metols cetseen M or Co (2 pts) Six drops of 0.5 M bromine in organic solvent is placed in each of two small test tubes. To the first test tube, 15 drops of 0.1 NaBr is added, and to the second test tube, 15 drops of 0.1 M Nal is added. Descbribe the likely observations for each test tube and state how these results couldbe used to distinguish between the anions. 4 pts) Fill in the chemical names in the table (Chemical Names in Textbook) Atom Atom Name Molecule Molecule Name Fl oride Flor ine Cl Cl2

Explanation / Answer

bromine in organic solvent = Br2(l) mostly

bormine in aqueous media = Br-(aq) mostly

iodine in aqueous media = I-(aq) mostly

then..

Tube 1 --> Br2(l) +Br-(aq) --> no reaction, only re-distribution due to affinity to solvent ( organic vs. aqueous)

Tube 2  --> I-(aq) +Br-(aq) --> expect redox reaction, Br- remains in Br, whereas I- forms I2(s), donating electrons to Br-
