Term
| Name the 6 general solubility rules: |
|
Definition
- Na, K, ammonium compounds are soluble in water
- Nitrates, acetates, and chlorates are soluble
- Most chlorides are soluble except those of Ag, Mercury(I), and lead. Lead(II) chloride is soluble in hot water
- Most sulfates are soluble except those of Ba, Sr, Pb, Ca, Hg
- Most carbonates, phosphates and silicates are insoluble, except theose of Na, K and ammonium
- Most sulfides are insoluble, except those of Ca, Sr, Na, K and ammonium

Term
| If the mixing tesults in a combo of ions that forms an insoluble compound, a _______-_____ rxn and ___________ will occur |
|
Definition
Double displacement
precipitation |
|
|
Term
| When does precipitation occur? |
|
Definition
| when the (inner) attraction b/w ions is greater than the attraction b/w the ions and their surrounding water molecules |
|
|
Term
|
Definition
| includes only those cmpnds and ions that undergo a chem change in a rxn in an (aq) solution |
|
|
Term
spectator ions take a part in the chemical rxn and are not found in the solution(both b4 and after rxn).
T or F |

Definition
|
|
Term
| Explain the process of the formation of the hydronium ion. |
|
Definition
| When a molecular compound contains a H atom bonded by polar cocalent bond, the compounds ionize, releasing the H+...making it attract other molecules or ions |
