Chemistry (solutions) Flashcards
Homogenous Mixture of solute dissolved in solvent.
Solution
Substance dissolved (smallest amount)
Solute
Allows chemical reactions.
Non-living systems (importance of solution)
Substance that dissolves the solute (largest amount)
Solvent
Blood plasma dissolves O2 and CO2
living systems
How much solute dissolves in as solvent at a specific temperature.
Solubility
Liquids that dissolve in each other.
Misciblity
High pressure
High solubility of gas (Like CO2 in soda).
Liquids that do not mix.
Immiscible
High temperature
High solubility (solids like sugar)
High temperature
Low Solubility (like oxygen)
Balance between dissolving and recrystallizing, No concentration change occurs over time.
Dynamic Equilibrium
Contain the maximum solute at a give temperature and pressure, excess solution remains undissolved.
Saturated Solution
Forms when a saturated solution is heated, allowing excess solute to dissolve.
Super saturated Solution
The amount of solute in moles per liter of solution .
Molar Concentration
The process of reducing the concentration of a solution by adding more solvent.
Dilution
Used to describe acid and base solution’s of Known concentration.
Quantitatively (concentrated Soln )
Used when comparing the concentrations of two similar solutions.
Qualitatively (Soln A, Soln B)
What describes isotopes?
same protons different neutrons
What does Avogadro’s number represent?
Number of particles in one mole
How many particles are in one mole of any substance?
6.022 × 10²³ particles
What does STP stand for in chemistry?
Standard Temperature and Pressure
What happens to concentration when more solvent is added to a solution?
Concentration decreases
What does it mean for a solution to be saturated?
Maximum solute dissolved
