What is hydrogen bonding
|
Unusually strong dipole-dipole attraction
|
|
|
Where does hydrogen bonding occur
|
Between molecules that have hydrogen atom covalently bonded to a small, highly electronegative atom
|
|
|
What is a homogenous mixture
|
Mixture so finely mixed that one region has same ratio of another region
|
|
|
What is a solution
|
All components are dissolved in same phase
|
|
|
What is a solvent
|
Component present in largest amount
|
|
|
What is a solute
|
Any other component
|
|
|
What is dissolving
|
Process of a solute’s mixing with a solvent
|
|
|
The move electrical attraction the what
|
The more likely it will dissolve
|
|
|
What is a saturated solution
|
solution in which no more solute can be dissolved
|
|
|
What is an unsaturated solution
|
Solution that has not reached the limit of solute that will dissolve
|
|
|
What is a concentration
|
The amount of solute dissolved per amount of solution
|
|
|
What does concentration describe
|
The quantity of solute dissolved in a solution in mathematical terms
|
|
|
What is a mole
|
Measure of submicroscopic particles in a solution
|
|
|
What does one more =
|
6.02 x10^23
|
|
|
What is molarity
|
Solution’s concentration expressed in moles of solute per liter of solution
|
|
|
What is solubility
|
Solute’s ability to dissolve in a solvent
|
|
|
What does solubility depend on
|
Attractions between the fundamental particles of the solute and solvent
|
|
|
What does infinitely soluble mean
|
A solution that has no practical point of saturation in a given solvent
|
|
|
What does insoluble mean
|
A material that doesn’t dissolve in a solvent to any appreciable extent
|
|
|
Water soluble solids usually dissolve better in what
|
Hot water
|
|
|
Solubility increases with what
|
Increasing temperatures because how water molecules have greater kinetic energy
|
|
|
What is a precipate
|
A solute that has come out of solution with decreasing temp
|
|
|
What is a super saturated solution
|
Hot saturated solution is allowed to cool slowly and without disturbance usually solute will stay in solution
|
|
|
Solubility of gases decrease with what
|
Increasing temperature
|
|
|
Gases are ejected due to what
|
High kinetic energy
|
|
|
What is also cause a decrease
|
High amounts of pressure
|
|
|
How do we purify the water we drink
|
By taking advantage of the differences in physical properties of water and the solutes or particles in contains
|
|
|
What does potable mean
|
Water that is safe for drinking
|
|
|
What are the steps in make water potable
|
Remove dirt and bacteria by mixing water and slaked lime and aluminum sulfate, aerate the water by cascading through a column of air, and water is treated with a disinfectant like chlorine
|
|
|
When are iodine tablets used
|
In developing countries
|
|
|
How can fresh water can be made from salt water
|
Distillation and reverse osmosis
|
|
|
What is distilliation
|
Vaporizing water with heat and then condensing the vapors into purified liquid water
|
