Bromine edit

Original - The chemical element bromine, purity 99.8%, amount ~2g, sealed in a colorless borosilicate glass vial (ampoule), sealed in a acrylic cube; cube edge length is 5 cm. Bromine is a dark reddish-brown liquid and a lighter-colored red-brown vapor.

Reason: High res, EV, meets criteria, looks cool.

Comment Per the discussion at commons FPC, I think it should be made clear in the caption and description that it is bromine vapour that causes the orange/brown colour in the vial, rather than coloured glass. Time3000 (talk) 11:10, 9 August 2009 (UTC)[reply]

Ok, done. Sasata (talk) 16:05, 9 August 2009 (UTC)[reply]

I think everyone will safely assume the container is clear. The important distinction is to indicate that the color difference is due to different states (light = gas, dark = liquid). Cacophony (talk) 12:32, 10 August 2009 (UTC)[reply]

Question. Why is there a scale on this? Is it really important for us to know how many millimeters tall this cube is? Kaldari (talk) 16:18, 10 August 2009 (UTC)[reply]
- Please read the infos at commons too: bromine on commons thanks, --Alchemist-hp (talk) 21:33, 10 August 2009 (UTC)[reply]
  - Your explanation there just says: "I set the scale discreetly on the right side for your imagination...I think for all the scientific objects it is better to have a scale for a size comparison." I wouldn't consider an acrylic cube to be a "scientific object". Why would we need to compare the sizes of acrylic cubes? It just doesn't make any sense to me. Perhaps it is an example of scalitis (addiction to drawing scales on photographs) :) Kaldari (talk) 23:36, 11 August 2009 (UTC)[reply]
    - There is a point having a scale here: it lets you judge the size of the meniscus, and hence get an idea of how viscous bromine is. That is surely worth having. Time3000 (talk) 10:55, 12 August 2009 (UTC)[reply]
      - There is no way you can tell anything about the meniscus from this photograph. You can't tell the orientation or shape of the open space in the cube, and the liquid isn't sitting level anyway. Depending on how the sides of the open space are curved and how the space is positioned, the bromine could have a wide range of viscosity. Kaldari (talk) 21:31, 17 August 2009 (UTC)[reply]
      - Since there doesn't seem to be a good reason why we need a scale in this photo, I've uploaded a new version without the scale. Feel free to revert if you disagree. Kaldari (talk) 21:46, 17 August 2009 (UTC)[reply]
        Now we have both: with and without a scale. Best regards, --Alchemist-hp (talk) 22:04, 17 August 2009 (UTC)[reply]
    - @Kaldari: if you like then upload please a second version if this file, similar to rev. image copy without a scale and original image with a scale --Alchemist-hp (talk) 22:13, 17 August 2009 (UTC)[reply]
