Ch.4 Flashcards
Which cations are always soluble with no exceptions?
Li+, Na+, K+, NH4+
Which anions are always soluble with no exceptions?
NO3-, C2H3O2-
Soluble: What are the exceptions with Cl-,Br- and I-?
When these ions pair with Ag+, Hg2^(2+) or Pb^(2+), the resulting compounds are insoluble
Soluble: What are the exceptions with SO4^(2-)?
When paired with Sr^(2+), Ba^(2+), Pb^(2+), Ag+, Ca^(2+) the resulting compounds is insoluble
Insoluble: What are the exceptions with OH- and S^(2-)?
- When they pair with Li+, Na+, K+, NH4+ the compounds are soluble
- When S^(2-) pairs with Ca^(2+), Sr^(2+), Ba^(2+) the compounds are soluble
- When OH- pairs with Ca^(2+), Sr^(2+), Ba^(2+) the compounds are slightly soluble
Insoluble: What are the exceptions with CO3^(2-) and PO4^(3-)?
When paired with Li+, Na+, K+, NH4+, the compounds are soluble
