Independent Variable
the variable being minipulated
Dependent Variable
the variable affected by the independent variable
cation
positively charged ion
anion

electrongravitivity
the tendency for an atom to gain an electron
hydrocarbon
nonpolar covalent compound
polarity
a compound that has an atom(s) sharing more of the electrons becoming partially negative
Hydrogen Bonding
IMF between two compounds when the compounds have a bond between a Hydrogen and either Oxygen, Nitrogen, and Flourine
London Dispersion Forces
Weakest IMF that occurs when a nonpolar compound randomly has a dipole moment
Is water polar?
yes
solution
a homogenous liquid between two or more substances
solvent
the dissolving agent/substance that other substances are getting dissolved in
solute
the substance being dissolved
Is water a universal solvent?
yes
What attracts to polar molecules
othe polar molecules
Auto-ionization
when one atom completely takes the sharing electron. Water does this
What is pH?
an exponential measurement of H+ concentration
What makes a substance more acidic?
a higher concentration of H+. pH of 7 or lower
What makes a substance more alkaline?
a higher concentration of OH-. a pH of 7 or higher
What makes carbon special chemically?
It can bond to a lot of different atoms. It can make 4 bonds. It can bond to other carbons.
