Talk:Clerici solution

A fact from Clerici solution appeared on Wikipedia's Main Page in the Did you know column on 15 November 2009 (check views). The text of the entry was as follows:

Did you know... that after adding thallium formate and thallium malonate to water, diamonds can float in it?

clear solution[edit]

Should it not be 'colourless'? (I assume that was what was meant but I'm not certain so I've left it as it is. Cambion (talk) 00:36, 16 November 2009 (UTC)[reply]

The statement, "The density of the saturated solution ... increases from 4.25 to 5.0 g/cm3 upon heating from 20 to 90 °C", is perhaps incorrect. The way it is currently written implies that simple heating will increase the density, which is difficult to believe. This statement is cited to reference 4, which is not readily available. However, reference 2 states that the density can be increased by heating the solution AND then adding additional salts, which implies that a greater concentration of salts leads to greater density. This is perhaps more likely. —Preceding unsigned comment added by 155.247.96.179 (talk) 13:40, 2 February 2011 (UTC)[reply]

It is the density of a certain entity called saturated solution (a solution in which the maximum amount of salt has been dissolved). In other words, the solution is not heated, but "prepared" at each temperature. Materialscientist (talk) 13:49, 2 February 2011 (UTC)[reply]
