Preceding the week long "Separation and Qualitative Determination of Cations and Anions" Lab, we did a pre-lab lab. This mini lab consisted of multiple solutions containing different cations and anions. From the reaction between the different combinations, we determined general solubility rules that helped us in our monster lab. The results below were used to create basic solubility rules:
cations
-all alkaline metals are soluble (Na, K, NH4)
-Lead is always insoluable except for NO3
-Silver is always insoluable except for NO3
anions
-NO3 is always soluble
-SO4 is always soluble except for lead
-Cl is always soluble except for Pb and Ag
-PO4 is generally soluble except for alkaline metals
