Chapter 19 Flashcards
Monoprotic acids
Acids that have one ionizable hydrogen
Triprotic acids
Acids that have three ionizable hydrogens
Acid properties
Taste sour, change color with indicator
Base properties
Tastes bitter, slippery
Conjugate base
Particle that remains when an acid has donated H ion
Conjugate acid
Particle that’s left when base accepts H ion
Hydronium ion
H3O, formed when H2O gains a hydrogen
Lewis acid
Electron-pair acceptor
Lewis base
Electron-pair donor
Arrhenius bases form…
A hydroxide ion, OH-
Neutralization and concentration equation
Ma X Va = Mb X Vb
Effective concentrations of acids and bases
Effective concentration = concentration / number hydrogens
Effective concentration = concentration / number hydroxides
Brønsted-Lowry acid
Hydrogen ion donor
Brønsted-Lowry base
Hydrogen ion acceptor
Arrhenius base
Yields OH- ions
Arrhenius acid
Acids yield H+ ions
Amphoteric
Can act as both an acid or base
Weak acid/base
Ionize slightly in (aq) solutions
Strong acid/base
Completely ionize in (aq) solutions
Alkaline solutions
Base solutions
pH
-log of H+ concentration
self-ionization
Two H2O molecules produce ions
Neutral solution
H+ and OH- are equal
Ion-product constant for H2O
Product of H+ ion and OH- ion concentrations for H2O
Acidic solution
H+ is greater than OH-
Basic solution
H+ is less than OH-
Acid dissociation constant
Ratio of concentration of conjugate acid times concentration of OH- ion to concentration of conjugate base
Acid dissociation constant
Ratio of concentration of ionized form of an acid to concentration of unionized acid
Equivalence point
Number of moles of H+ equals number of miles of OH-
End point
Point of neutralization
Standard solution
Solution of known concentration
