Question Answer
Define electronegativityis a measure of an atom's attraction for the electrons in a bond.
What is a solution?a mixture of a solvent and a dissolved material called the solute
Characteristics of solute particlessingle atoms, single ions, or small molecules. They are evenly dispersed throughout the solvent
what is solubility?How much of a solute will dissolve in a solvent at a given temperature.
what is miscible?liquids that are soluble in each other in all proportions
Define a saturated solutioncontains all the solute that will go into solution at a given temperature
Describe an unsaturated solutioncontains less than the max amount of solute that will dissolve at a certain temp.
What is percent concentration?(amount of solute) / (amount of solvent or solution)
Molarity formula is?#moles of solute / # liters of solution
molality formula?#mol of solute / kg solvent
Define a polar covalent bondbond between two different nonmetal atoms
Define a nonpolar covalent bondbond between 2 nonmetals of the same energy (2 atoms of the same nonmetal element)
what is an electrolyte?is a compound which dissolves in water to produce a solution which conducts electricity
What is nonelectrolyte?a compound whose water solution does not conduct electricity
Describe a weak electrolyte:compound whose solution conducts poorly
Strong electrolyte is?compound whose solution conducts strongly
What is a covalent bond?a chemical bond that arises from sharing electrons between two atoms
Ionic bond is?a chemical bond that results from the electrostatic attraction between ions of opposite charge
Define an ION-DIPOLEan attraction between the partially charge end of a polar molecule and an oppositely charged ion.
What is a HYDROGEN-BONDhydrogen is covalently bonded to one of the highly electronegative atoms: N, O, or F, the partially positive hydrogen in that molecule is attracted to O, N, or F in another molecule
describe DIPOLE-DIPOLEattraction between the partially positive end of one polar molecules and the partially negative end of another polar molecules.
Define DIPOLE-INDUCED DIPOLEattraction between a polar and a non polar molecule
what are london forcesattraction between two nonpolar molecules.
What is Arrhenius Theory of Acids?all acids are soluble in water
Name some factors that affect solubilitypressure, polarity, temperature(gas less soluble in higher temps; solids more soluble in hotter temps)
list factors that affect rate of dissolving of solutes in solventsTemperature (if increases then rate increases), Stirring increases rate
