Flashcards in Solutions Deck (21):
What are the properties of a solution?
-homogenous mixture of two or more substances e.g. Sugar and water
-macroscopic properties do not vary within the sample
-components cannot be separated by filtration, but can be separating by things like boiling
-no components are large enough to scatter visible life
The substance that is more plentiful in a solution
The substance that is less plentiful in a solution
When the solvent has dissolved the maximum amount of solute possible at a certain temperature, and some solid particles remain undissolved
Saturated solutions are an _______ system where solid particles continually dissolve in the solvent and dissolved particles fall out of solutions
Solutions soluble in all properties, never become saturated
How can intermolecular forces cause the volume of a solutions to differ from the sum of the volume before mixing?
Strong IMF's can pull molecules together and decrease volume
Always infinitely soluble in each other
Solutions formed by melting, mixing, and solidifying
How does steel differ from iron?
Carbon fills some spaces in iron ions
Iron lacks ___________ bonds
In which one elements atoms fill up the spaces of another molecules molecule
Alloy where atoms from one element are substituted for others
What is the equation for molarity?
M=(moles of solute)/(liters of solutions)
Molarity ______ change with temperature
Mole fractions __________ change with temperature
What factors affect solubility?
The mass of solute that dissolves in a saturated solution composed of a specific mass of solvent at a specific temperature
The solubility of most solids increases as temperature increase, as the process is usually _________________
What are the properties of a suspension or mechanical mixture?
-heterogenous mixture of two or ore substances, e.g sand and water
-macroscopic properties are different at different locations within the sample
-in some cases, components can be separated through filtration
