Elite X-Naut Posted November 22, 2015 Report Share Posted November 22, 2015 (edited) Hey guys! Today in Chemistry SL we learned that the solubility table/guidlines are not given on the data booklet for double displacement reactions. Every site or picture I researched are not specific enough to overlap a lot with each other. Is there any solubility table specific to what the IBO wants us to know? If so, what are the easiest ways to memorize the rules? The chart that we are currently using is this: http://imgur.com/imn3E3x Edited November 22, 2015 by Elite X-Naut Reply Link to post Share on other sites More sharing options...
Msj Chem Posted November 22, 2015 Report Share Posted November 22, 2015 You are not required to know the solubilities of different salts for the IB. The IB does not expect students to memorise that list that you posted. Reply Link to post Share on other sites More sharing options...
Elite X-Naut Posted November 24, 2015 Author Report Share Posted November 24, 2015 (edited) If the IB does not expect us to memorize the solubilities, does this mean there will be no questions on the exam involving the state of the compound or for predicting if a reaction will even occur?

Not based on the solubility rules, no. However, if your teacher wants you to learn them, then you should.May I ask what topic you are studying?

Elite X-Naut Posted November 25, 2015 Author Report Share Posted November 25, 2015 (edited) At the moment we are studying Topic 1 and it involves stoichiometry, but we did spend a day reviewing each type of reaction, predicting products, and balancing equations.The teacher wants us to know them because it's not on the data booklet during exams, however, searching solubility rules online for an easy way to memorize them gives different variations because it's 'general' solubility guidelines.

I see, I guess it won't hurt to know the solubility rules, but they are not included in the new syllabus. The solubility product constant (Ksp) was in option E (HL) in the old syllabus but has been taken out as far as I know. 1 Reply Link to post Share on other sites More sharing options...
