What cations and anions are always soluble?
Solubility Rules
- Salts containing Group I elements (Li+, Na+, K+, Cs+, Rb+) are soluble .
- Salts containing nitrate ion (NO3-) are generally soluble.
- Salts containing Cl -, Br -, or I – are generally soluble.
- Most silver salts are insoluble.
- Most sulfate salts are soluble.
- Most hydroxide salts are only slightly soluble.
Are all anions soluble in water?
They are summarized in the table below . Ionic compounds with group 1 (or 1A) metallic cations or ammonium cations, NH4+, form soluble compounds no matter what the anion is….Predicting Solubility of Ionic Compounds in Water.
| Category | Soluble anions |
|---|---|
| Ions | NO3- and C2H3O2- |
| Except with these ions | No exceptions |
| Examples | Bi(NO3)3, and Co(C2H3O2)2 are soluble. |
Which anions are generally soluble in water?
most Cl-, Br-, and I -salts are soluble, with the noteable exceptions of salts that contain Ag+ and Pb2+ and Hg22+. all acetates, chlorates, and perchlorates are soluble. most sulfate SO42- are soluble with the exceptions of salts containing Ba2+, Pb2+ and Ca.
Is CH3NH3Br acidic basic or neutral?
CH3NH3Br is the same thing as the first one, it is acidic. The stronger the base/acid, the weaker its conjugate is, and vice-versa.
