Explanation:

Step1: Recall acid - base - salt definitions

Acids release H⁺ in solution, bases release OH⁻, and salts are products of acid - base reactions.

Step2: Classify HCl

HCl releases H⁺ in solution, so it is an acid.

Step3: Classify KOH

KOH releases OH⁻ in solution, so it is a base.

Step4: Classify NaOH

NaOH releases OH⁻ in solution, so it is a base.

Step5: Classify NaCl

NaCl is formed from the reaction of HCl and NaOH, so it is a salt.

Answer:

Acid: HCl
Salt: NaCl
Base: KOH, NaOH
Alkaline: KOH, NaOH
