Exam 1 Flashcards
Molarity, M, is defined as moles of solute dissolved in
1L of solution
Soluble
able to be dissolved
Miscible
two liquids that are soluble with each other
insoluble
precipitate, not dissolvable
solution
a homogenous mixture
solute
any component in the solution is not the solvent
solvent
the component in the greatest amount in a mixture
molarity
a chemists concentration (6.022 x 10^23)
Dilution equation for molarity
M1V1=M2V2
analyte
the concentration of a solute in a sample that needs to be determined
titrant
a standard solution with a known concentration
Electrolyte
a solute that produces ions in a solution. (electrical current can flow through due to freely moving ions)
Strong electrolyte
conducts, dissociates, forming ions
Weak electrolytes
partially dissociates, partially conducts
Nonelectrolytes
doesn’t conduct, doesn’t contain ions, doesn’t dissociate
Determine if something is strong or weak (electrolyte)
If the compound is ionic and soluble it is strong, if it is insoluble then its a non
If the compound is covalent and its an acid, the strength of acid will determine its electrolyte strength, if it’s a base then it’s weak, if its not an acid or base its a non electrolyte
Acids
need to have an H, listed first in the formula gives H proton
Base
Needs attractor of OH, lone pair attracts H proton
When an acid and base combine…
they neutralize each other and create water and salt (ionic compound)
Pressure
force of particles hitting walls (how hard and how often)
Temperature
measure of average kinetic energy
Volume
volume of the gas is the volume of the container
moles
amount of stuff
Pressure decreases as you go up in elevation due to
fewer particles
