|
Oxidation is the ____. The oxidation number gets ____ during an oxidation reaction. |
loss of electrons more positive |
|
|
The oxidation number of an atom is ___. The oxidation of an ion is ___. |
zero its charge |
|
|
Reduction is the ____. The oxidation number gets ___ during a reduction reaction. |
gain of electrons more negative |
|
|
Often an oxidation and reduction reaction occur simultaneously this is called a ____. |
Redox reaction |
|
|
The oxidizing agent is ____. The reducing agent is ____. |
Reduced oxidized |
|
|
If an ion is neither oxidized or reduced it is called a _____. |
spectator ion |
|
|
Solution |
A homogeneous mixture of 2 or more substances where one substance I'd dissolved in another |
|
|
Sloute |
The substance being dissolved; it is the least abundant |
|
|
Solvent |
The substance the solute dissolves in; it is the most abundant |
|
|
Soluble |
Dissolve in a solvent (salt dissolves in water) |
|
|
Insoluble |
Solute don't dissolve (rocks do not dissolve) |
|
|
Miscible |
When both solute and solvent are liquids (water and alcohol) |
|
|
Immiscable |
Both solute solvent are liquid but do not mix (Water an oil) |
|
|
Precipitation |
the opposite of dissolving |
|
|
Only a certain amount of solute can dissolve in a given amount of solvent at constant temperature and pressure |
No back |
|
|
How does temperature affect solubility |
Solid/liquid solutions: solubility increases at temperature increases Gas/liquid solutions: solubility decreases as temperature increase (hot soda goes flat |
|
|
How does pressure affect solubility |
Pressure is only a factor gas/liquid solutions Solubility increases as pressure increases |
|
|
Saturated |
A solution which has the maximum amount of solute dissolved (NACL 10g of 100 ml H2O) all would dissolve because that is max |
|
|
Unsaturated |
A solution which more solute could be dissolved (NaCl 5g of 100 ml H2O) dissolves all but has more room for more NaCl |
|
|
Superstaurated |
A solution which contains more solute than a saturated solution should contain at room temp; unstable (NaCl 15g of 100 ml H2O) would see extra 5 g at boot of water But yiu can heat it up to make it dissolve |
|
|
Molarity equation |
M= moles of solute/liters of solution |
|
|
Dilution |
M1v1=m2V2 |
|
|
Electrolytes dissolving in water NaCl (s) |
Na+(aq) + Cl-(aq) |
|
|
Covalent compounds ____ when they dissolve & are called ____. |
Do not dissolve Nonelectrolytes |
|
|
