Discussion Overview

The discussion revolves around a chemistry homework assignment focused on identifying the colors of the first four halogens (fluorine, chlorine, bromine, and iodine) in three physical states (solid, liquid, gas) and two solvents (water and organic solvents). The scope includes conceptual understanding and factual recall related to the properties of halogens.

Discussion Character

  • Homework-related
  • Conceptual clarification

Main Points Raised

  • One participant provides some color observations for chlorine, bromine, and iodine in solid and gaseous states but is uncertain about the remaining colors.
  • Another participant points out that bromine is a liquid at room temperature, not a solid, and notes the need to include fluorine in the discussion.
  • Corrections are made regarding the diatomic nature of the halogens, with a suggestion to include subscripts '2' for fluorine, bromine, iodine, and chlorine.
  • One participant expresses frustration with the colors of chemicals and acknowledges forgetting about the diatomic nature of the halogens.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the complete set of colors for the halogens, and there are multiple corrections and suggestions regarding the initial claims made by the original poster.

Contextual Notes

Some assumptions about the states and colors of halogens may be missing, and there is a lack of clarity on the colors in specific solvents. The discussion does not resolve the complete list of colors for all states and solvents.

Homework Statement


This is an assignment given by my chemistry teacher. Plz help.

State the colors of the first 4 halogens in:
(i) the three states: (s), (l), (g)
(ii) the two solvents: water, organic solvents


The Attempt at a Solution


I had some figured out:
Cl(s): Yellowish-green
Br(s): Brownish-red
I(s): Black
I(g): Purple

But I still can't figure out the other colors.
Would appreciate the help, thanks.

Please help!
 
I do not know the answer to your question so I would suggest you talk to your chemistry teacher.

Corrections
-bromine is a liquid at room temperature, not a solid.
-iodine appears twice
-need to include flourine
-flourine, bromine, iodine and chlorine each need a subscript '2' because they are diatomic molecules
-flourine and chlorine are gases

I hope this helps
 
Diatomic molecules... Forgot that >.<
Thanks for the thread. (Colors of chemicals are really frustrating!)
