tritation:
know the steps!
conducts electricity (electrolyte); source of ions (hydronium)
acid
base - methyl orange
yellow
oxyacid
any acid that contains oxygen.
What are the strong acids?
HClO₄>HI,H₂SO₄(pKa1)>HCl,HBr>HNO₃
*Conjugate base of a strong acid (Ka>>1) is very weak (Kb < 10⁻¹⁴)
*Though, the conj base of a weak acid (Ka between 10⁻¹⁴) is a weak conj base (Kb between 10⁻¹⁴ and 1)
strong electrolytes
-100% ionize/dissociate (break apart)
-conduct electric current well
-strong acids/bases
"salt"
a compound formed by replacing hydrogen in an acid by a metal (or a radical that acts like a metal)
acids that contain 3 elements (hydrogen, nonmetal, and oxygen)
oxyacids
The equivalence point for strong acid/strong base titration is always ___
7
triprotic
acids that contain three ionizable hydrogens
any substance that increases the hydronium concentration in solution
Acids
aqueous
similar to or containing or dissolved in water
hydrochloric acid
an aqueous solution of hydrogen chloride.
acidic solution
contains more hydrogen ions than hydroxide ions
Acid
Substance that tastes sour, or tart and turns blue litmus red
hydrogen ions
At the same concentrations, strong acids produce more___?___ that weak acids
neutralization
process in which strong acid and strong base produce water (neutral pH = 7) and neutral salt, e.g. HCl + NaOH -- NaCl + HOH; net ionic equation shows only H3O+ + OH- -- 2HOH
pH Scale
measure of the concentration of hydrogen ions in a solution
arrhenius acid
a chemical compound that increases the concentration of hydrogen ions in aqueous solution
Weak Acid
Releases few hydrogen ions in aqueous solution.
Base/Alkali
Has a pH value of more than 7
hydronium ion
hydrogen ion combines with a water molecule to form a hydronium ion, H3O(+)
false
oxygen is given off when acids wear down metals t or f
A larger Ka means....
favor product side, more ionized
pH
a value that indicated the acidity or alkalinity of a solution on a scale of 0-14, based on the proportion of H+ ions.
conjugate acid
the particle formed when a base gains a hydrogen ion
conjugate base
the particle that remains when an acid has donated a hydrogen ion
Acid characteristics
have a sour taste, reacts with certain metals to produce hydrogen gas, reacts with carbonates and bicarbonates to produce carbon dioxide gas
Effects of Acid rain
damage statues and buildings, destroy forests, and kill fish
Sodium Hydroxide
An example of a very strong alkali with a pH of 14.
bronsted base
a molecule or ion that is a proton acceptor
Strong "hydro" acids -names
hydro- bromic / chloric / iodic -acid
Arrhenius (Traditional) Acids
acids that contain and release H+ ions when dissolved in water
hydrogen or hydronium ion
is an atom of hydrogen that has lost its electron
Equivalent Masses (acid or base)
the number of H= or OH- ions involved in the titration
is NH3 + HCl ----> NH4Cl Arrhenius? B-L? Lewis?
no (not aqueous); yes (base is NH3; acid is HCl); yes
