Solution
Homogeneous mixture of two or more substances
Solute
Substances that are present in smaller amounts
Solvent
Substance that is present in the largest amount
Electrolyte
A solute that conducts electricity when dissolved in water
Non-Electrolyte
A solute that does not conduct electricity when dissolved in water
Molarity Formula
Molarity = moles of solute/liters of solution
Precipitation Reaction
An insoluble solid that separates from a solution during a precipitation reaction
Ionic Equation
Shows all dissolved species as free ions
Net Ionic Equation
Shows only the species involved in the reaction
Properties of Acids
Proton Donor
Have a sour taste
Change litmus dye from blue to red
Aq conduct electricity
Properties of Bases
Proton Acceptor
Bitter taste and feels slippery
Change litmus dye from red to blue
Aq solutions conduct electricity
Strong Acids
HCl - Hydrochloric Acid
HBr - Hydrobromic Acid
HI - Hydroiodic Acid
HNO3 - Nitric Acid
H2SO4 - Sulfuric Acid
HClO4 - Perchloric Acid
Oxidation Reaction
Rxn that loses electrons
Reduction Reaction
Rxn that gains electrons
OIL RIG
Oxidation Is Loss e-
Reduction Is Gain e-
Reducing Agent
Causes an element like O2 to be reduced because of another element like Mg
Oxidizing Agent
When an element takes e- from another one it oxidizes the element it takes it from
Daltons Law of Partial Pressure
Pi = Xi * PT where Xi = ni/nt
Density for Gas
D = PM/RT where M = molar mass
Also another Variation is:
M = dRT/P
Ideal Gas Law
PV = nRT
R is the gas constant
Combined Gas Law
P1*V1/n1*T1 = P2*V2/n2*T2
Charles Law Formulas
V1/T1 = V2/T2
and
P1/T1 = P2/T2
Boyles Law
P1*V1 = P2*V2
Atmospheric Pressure Conversions
1 at = 760 mmHg = 760 torr
