(hydroiodic acid), HNO3 (nitric acid), H2SO4 (sulfuric acid), HCLO4 (perchloric acid)
Common weak Acids (focus on this) - Answer- HF (hydrofluoric acid), H3PO4
(phosphoric acid), CH3COOH (acetic acid), and H2CO3 (carbonic acid)
Common Strong Bases - Answer- LiOH (lithium hydroxide), NaOH (sodium hydroxide),
KOH (Potassium Hydroxide), RbOH (rubidium hydroxide), CsOH (cesium hydroxide),
Ca(OH)2 (calcium hydroxide), Sr(OH)2 (strontium hydroxide), and Ba(OH)2 (barium
hydroxide)
Common Weak Bases - Answer- NH3 (ammonia)
When writing ionic equations, separate... - Answer- Strong acids, Strong bases, and
soluble ionic compounds into ions
strong acids and bases, and soluble ionic equations are... - Answer- Strong electrolytes
Keep.... as they are when writing ionic equations - Answer- Weak acids, weak bases,
insoluble ionic equations, and water
Oxidation and reduction cannot occurs without the other (term) - Answer- Redox
Looses electron= term, agent, what happens to oxidation number - Answer- Oxidized,
reducing agent, increases oxidation number
