Hello all I have a few questions about Precipitates and Solubility Rules (a) How do you write an equation for the dissociation of a salt in a solution? (b) How do you write a net ionic equation? (c) Which ions tend to form soluble salts? insoluble salts? ( Pb[2+] Na[+], k[+], NH4[+], Ag[+], NO3[-]. OH[-]. Cl[-]. CO3[2-], PO4[3-] For example is K2C03 the same as K2C03 --> 2K + CO3? How do you know when to put the coefficient in front of the ion? It also says to write a net ionic equation for the formation of each precipitate that was formed in the experiment (omit spectator ions) K3PO4 + BaCl2 ---> ??? Also is there any good way to memorize or derive the solubility rules?? Any help is greatly appreciated. Thanks!
