AP Chemistry unit 8 Flashcards (ᵔꈊᵔ っ)∋

for my memorization

What are the six strong acids?

HCL, HBR, HI, H2S04, HNO3, HCLO4

[hydrochloric acid (HCl), hydrobromic acid (HBr), hydrochloric acid (HI), nitric acid (HNO3), perchloric acid (HClO4), and sulfuric acid (H2SO4)]

Strong acids and bases_

ionize completely in water, producing H+ or OH- ions

How do we find the pH of a strong acid?

By using the formula pH = -log[H+], where [H+] is the molarity of the acid which gives the concentration of hydronium ions in solution

How do we find the pOH of a strong base?

By using the formula pOH = -log[OH-] then 14- ans. Here [OH-] is the molarity of the base which gives the concentration of hydroxide ions

What are the eight strong bases?

NaOH, KOH, LiOH, Ba(OH)₂, Ca(OH)₂, Sr(OH)₂, CsOH, RbOH

[sodium hydroxide (NaOH), potassium hydroxide (KOH), lithium hydroxide (LiOH), barium hydroxide (Ba(OH)₂), calcium hydroxide (Ca(OH)₂), strontium hydroxide (Sr(OH)₂), cesium hydroxide (CsOH), and rubidium hydroxide (RbOH)]

What is an easy way to remember the strong bases?

Any group 1-2 element hydroxide

Are there any special steps to be taken when finding pOH of a group 2 hydroxide?

Yes, use the 2:1 ratio

eg 0.010M Ca(OH)2 pOH= -log[0.020]
