Q

Solvation

A

Dissolving process in solid and liquid solutions
Solvent molecules (ex water) surround and separate solute molecules/ions (ex salt)

Q

Can you dissolve anything

A

Yes and no
Yes- polar solvents dissolve polar solutes vice versa with nonpolar
No- polar cannot dissolve nonpolar (water and oil)

16
Q

Dynamic equilibrium

A

Both processes (Dissociation and its reverse) are occuring at same rate

17
Q

Supersaturation

A

Solution contains more dissolved solute than it does at equilibrium

18
Q

Factors that affect rate of solution

A

Temp
Stirring
Surface area exposed to solvent

19
Q

How does temp affect solubility

A

Higher temps help solids and liquids dissolve
Adding heat = adding more reactant
Heat is product of gases dissolving

20
Q

Effervesecence

A

Escape of gas from liquid-gas solution
Ex: Carbon dioxide from soda
