Chapter 6: Solutions Flashcards
Solution
Solute
Solvent
Aqueous Solution
- homogenous mixture
- the substance in the mixture present is lesser than quantity
- the substance present in the largest quantity
- solution where solvent is water
Solubility
-Factors that affect solubility
how much of a particular solute can dissolve in a certain solvent at a specified temperature
- polarity of solute + solvent: like dissolves like
- temperature: increase in temp, increase in solubility
- pressure: usually has no effect on liquids but has an effect on gases
Henry’s Law
the number of moles of a gas dissolved in a liquid at a given temperature is proportional to the partial pressure of a gas above the liquid
Concentration
amount of south dissolved in a given amount of solution
Weight/ Volume Percent
%m/v= grams of solute/ mL of solution x 100%
Mass/ Mass Percent
%m/m= grams solute/ grams solutions x 100%
Molarity
M= moles solute/ L solution
Dilution
M1V1= M2V2
Hypertonic
Hypotonic
- solute concentration of fluid surrounding cells higher than inside results in a hypertonic solution causing water to flow into the surroundings; causing a collapse which is crenation
- solute concentration of fluid surrounding cells too low, results in a hypotonic; causes water to flow into a cell, which ruptures causing hemolysis
Pickling
Pickling solution is hypertonic so water can be pulled out of the cucumber in order to be replaced with the brine.
