Quantitative Chemical Analysis Chapter 6 Exam Questions with Verified Solutions (Graded A+)
Acid - Answers A substance that increases the concentration of H+ when added to water
acid dissociation constant (Ka) - Answers Equilibrium constant for the reaction of an acid, HA, with H20
ka=products/reactants
Acidic solution - Answers a solution in which [H+] is greater than [OH-]
Amine - Answers a compound with the general formula RNH2, R2NH, or R3N, where R is any group of
atoms
Ammonium ion - Answers NH4+
Aprotic solvent - Answers one that cannot donate protons (hydrogen ions) in an acid-base reaction
Autoprotolysis - Answers the reaction in which two molecules of the same species transfer a proton
from one to the other
Ex. CH3OH+CH3OH=CH3OH2+CH3O-
Base - Answers A substance that decreases the concentration of H+ when added to water
Base hydrolysis constant (Kb) - Answers the equilibrium constant for the reaction of a base, B, with H2O
Kb=products/reactants
Basic solution - Answers contains more hydroxide ions than hydrogen ions
Bronsted-Lowry acid - Answers proton donor
Entropy - Answers a measure of the disorder of a system
Equilibrium constant - Answers the ratio of product concentrations to reactant concentrations at
equilibrium, with each concentration raised to a power equal to the number of moles of that substance
in the balanced chemical equation
Keq= products/reactants
Exothermic - Answers Change in H is negative, heat is given off when products form
Gibbs Free Energy - Answers the energy of a system that is available to do work at a constant
temperature and pressure
Hydronium ion - Answers H3O+
Ion pair - Answers A closely associated anion and cation, held together by electrostatic attraction. In
solvents less polar than water, ions are usually found as ion pairs.
