Question

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)

Answer 1

C) CH3COOH Is the answer you are looking for

Step-by-step explanation:

This one makes the most sense and the other ones don't fit in with the acids they aren't Acidic those are either bases or neutrals! :)

Hope this helps! :)

Answer 2

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
