BronxNerd Posted April 3, 2011 Report Share Posted April 3, 2011 Hey people! My Design Lab 2 Prompt is: Investigate a factor that distinguishes salts. Here is my question: How is the yield of Sodium in a Sodium Halide affected by different halides? Reply Link to post Share on other sites More sharing options...
Keel Posted April 3, 2011 Report Share Posted April 3, 2011 Hello,Firstly, what do you mean by yield? After a certain reaction? Secondly how are you going to measure this 'yield'? When I saw the 'prompt' the first thing that came into mind was the pH of salts across a certain group e.g. pH of oxide solutions across period 3. Did you recently do acids and bases? If you did then this might be the correct approach. Reply Link to post Share on other sites More sharing options...
ervo Posted April 14, 2011 Report Share Posted April 14, 2011 (edited) Melting point, solubility, colour, aqueous pH (as mentioned below) are all things you could investigate, related to Periodicity or Acids and Bases.

Drake Glau Posted April 15, 2011 Report Share Posted April 15, 2011 (edited) Personally I'd go for the pH suggestion. Probably the easiest to do and easiest to measure whether you use litmus paper or some fancy probe Edited April 16, 2011 by Desy ♫ no insulting!

ervo Posted April 15, 2011 Report Share Posted April 15, 2011 (edited) If you use litmus it's a "yes or no" situation - acid or not / alkali or not. Universal indicator would be an improvement, though it's inaccurate and still very qualitative. You want a probe to get any meaningful data. If this is a DCP exercise, then not using a probe will guarantee you won't get a "complete" for that criterion. Edited April 16, 2011 by Desy ♫ no fighting!

Drake Glau Posted April 15, 2011 Report Share Posted April 15, 2011 (edited) And yes, meant the universal indicator, sorry. Litmus paper was just the first thing that came to my head O.o Edited April 16, 2011 by Desy ♫ no fighting!!! Reply Link to post Share on other sites More sharing options...
