Classify each of the compounds below as strong or weak acids, strong or weak bases, or salts:

A. HCl
B. KOH
C. NH4NO3
D. H2SO4
E. NH4OH
F. H3PO4
G. NaOH
H. HClO4
i. Mg(OH)2
J. H2CO3
K. BaSO4
l. HC2H3O2

The numbers are sub(little numbers

Look in your text/notes. If the acid or base is listed in the table of ionization constants it is weak. It it isn't listed it is strong. If it has an ionizable H it is and acid. Look for bases to have OH groups. It it isn't an acid or base it is a salt.

To classify each of the compounds as strong or weak acids, strong or weak bases, or salts, you need to understand the definitions and characteristics of acids, bases, and salts.

Acids and bases are classified based on their ability to donate or accept protons (H+ ions). Strong acids and bases completely dissociate in water, meaning they fully ionize and release H+ or OH- ions. Weak acids and bases only partially dissociate in water.

Salts, on the other hand, are compounds that result from the neutralization reaction between an acid and a base. They are formed when the H+ ions from the acid are replaced by cations (positively charged ions) while the OH- ions from the base are replaced by anions (negatively charged ions).

Now, let's classify each of the compounds:

A. HCl: HCl is a strong acid because it completely dissociates in water, releasing H+ ions. It is a strong acid regardless of the state (solid, liquid, or gas) it is in.

B. KOH: KOH is a strong base because it fully dissociates in water, releasing OH- ions. Similar to HCl, it is a strong base regardless of its state.

C. NH4NO3: NH4NO3 is a salt, not an acid or base. It is formed by the reaction of NH4+ (ammonium ion) from a weak base (NH4OH) and NO3- (nitrate ion) from a strong acid (HNO3).

D. H2SO4: H2SO4 is a strong acid because it completely dissociates in water, releasing two H+ ions. It is commonly known as sulfuric acid.

E. NH4OH: NH4OH is a weak base because it only partially dissociates in water, releasing NH4+ ions and some OH- ions.

F. H3PO4: H3PO4 is a weak acid because it only partially dissociates in water, releasing H+ ions. It is commonly known as phosphoric acid.

G. NaOH: NaOH is a strong base because it completely dissociates in water, releasing Na+ ions and OH- ions. It is commonly known as sodium hydroxide.

H. HClO4: HClO4 is a strong acid because it fully dissociates in water, releasing H+ ions. It is commonly known as perchloric acid.

i. Mg(OH)2: Mg(OH)2 is a weak base because it only partially dissociates in water, releasing Mg2+ ions and some OH- ions. It is commonly known as magnesium hydroxide.

J. H2CO3: H2CO3 is a weak acid because it only partially dissociates in water, releasing H+ ions. It is the chemical formula for carbonic acid.

K. BaSO4: BaSO4 is a salt formed from the reaction between barium ions (Ba2+) and sulfate ions (SO42-). It is commonly known as barium sulfate.

l. HC2H3O2: HC2H3O2 is a weak acid because it only partially dissociates in water, releasing H+ ions. It is commonly known as acetic acid.

Remember, it's important to understand the definitions and characteristics of acids, bases, and salts to determine their classification accurately.
