15) circle one and tell whya. ch3cooh is a n) (acid, base, salt)b. nh4cl is a(n) (acid, base, salt)c. koh is a(n) (acid, base, salt)d. h3po4 is a(n) (acid, base, salt)e. cabr2 is a(n) (acid, base, salt)

The answers to the given questions are:

a. CH3COOH = acid
b. NH4Cl = salt
c. KOH = base
d. H3PO4 = acid
e. CaBr2 = salt

Reasons:

a. This compound is also known as acetic acid, the acid found in vinegar. It can be observed that the compound has a hydrogen ion which makes the compound acidic.

b. Ammonium chloride is a salt because it is the product of an acid (hydrochloric acid, HCl) and base (ammonium hydroxide, NH4OH)

c. Potassium hydroxide is a base because of the presence of OH ion

d. Phosphoric acid is a base because it has 3 hydrogen ions that contributes to its acidity
