What is Chloric and Perchloric acid are Strong acids while Chlorous and Hypochlorous Acids are weak. What is Chloric acid is HClO3, Perchloric is HClO4, Chlorous is HClO2, and Hypochlorous is HClO.
What is the formula for the autoionization of water? What is the equilibrium constant for this AND what is its value? Are all species involved? Why or why not?
What is H2O (l) + H2O (l) ⇌ OH- + H3O+?
What is Kw=1*10^-14=[OH-][H3O+]?
What is NO, not all species are involved because we are using Liquid water, so liquids are not in equilibrium constants.

Is ammonia a Lewis, Arrhenius, and or Bronsted-Lowry Base or Acid and why?
What is an Arrhenius, Lewis, and Bronsted-Lowry Base (ALL 3)
What does it mean to be a strong acid/ base? How about a weak acid/base? What does IONIZATION mean and how does it apply?
What is ionization is the process of forming ions, from an acid or base in this case? What is strong acids/bases are fully ionized in water? What is weak acids/bases are NOT fully ionized and therefore are reversible?
You find the pH of a pool in a new environment to be 8.45. What is the hydronium ion concentration in this pool?
What is 2.8 x 10^-6
A 0.050 M solution of a monoprotic weak acid has pKa = 4.20 at 25 °C, what is the pH? What do you think a monoprotic acid is? (extra 100 if correct)
What is 2.75? What is an acid with ONE proton to give away? (mono=one, protic= related to proton)
Who was the SECOND president of the United States?
Who is John Adams?
What is a Lewis Acid?
A chemist is studying the acid–base behavior of four different compounds in water. Compound A has an acid dissociation constant of Ka = 3.2 × 10⁻⁵, while Compound B has a base dissociation constant of Kb = 1.0 × 10⁻³. Compound C was measured to have a pKa of 9.4, and Compound D was found to have a pKb of 4.8. Based on these values, determine which compound is the most acidic and which is the least acidic, put in order from MOST acidic to LEAST acidic.
You have 0.0025 molar barium hydroxide in a certain industry cleaner. What is the pH of this soap?
What is 11.7?
An aqueous solution is 0.050 M sodium acetate at 25 °C. Given Ka for acetic acid = 1.8×10^-5, what is the pH?
What is 8.7?
What is the name of the 4 subunit protein in charge of carrying oxygen in our blood around the body and keeping us alive? (extra points: what is the gas that binds EVEN more effectively to this protein, making it a dangerous thing to encounter)
What is hemoglobin?
(Extra: what is Carbon Monoxide?)
Why does Kw=Ka*Kb for ONLY Conjugate pairs?
What is you need to be able to cancel and isolate [OH] and [H]
Ka= [H][A]/[HA]
Kb= [OH][HA]/[A]
([H][A]/[HA])*([OH][HA]/[A])-->
[H]*[OH]=Kw
A solution is made by mixing 150.0 mL of 0.0200 M HNO₃ and diluting to a total volume of 500.0 mL at 25 °C. Assuming complete dissociation and no other acids or bases are present, what is the hydroxide ion concentration, [OH⁻], of the final solution?
What is 1.67 x 10^-12

What is 2.24 x 10^-6?
This NFL team went to and lost 4 super bowls in a row in the early 90s, making them one of the greatest teams to never win, who was this team? (extra points: 2 of these super bowls were against the same team, the BEST team in the history of the NFL, who was that team?)
Who are the Buffalo Bills?
(extra: who are Dallas Cowboys?)
