How do I use the "Solubility Rules" presented in Figure4.7, page 167?

The solubility guidelines presented on page 167 providea "rule of thumb" guide for you to predict the solubility of ioniccompounds in water. The dissociation of ionic compounds often referred to"salts" for historic reasons, was observed by Svante Arrheniusat the end of the nineteenth century. His work explained why ionic saltsdissolved in water conducted electricity because the resulting hydratedcations and anions could act as charge carriers in the aqueous solution.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
