A

An Arrhenius acid is a substance that increases hydrogen ion concentration, while a Lewis acid accepts an electron pair.

B

A Lewis acid must always be a solid at room temperature, while an Arrhenius base is a liquid.

C

Both Arrhenius acids and bases must be soluble in water to be considered effective in business transactions.

D

An Arrhenius acid can never be a Lewis acid in any chemical transaction.

Understanding the Answer

Let's break down why this is correct

Answer

In a business that sells chemical products, the Arrhenius view tells us that an acid like hydrochloric acid releases H⁺ ions when it dissolves in water, so the company must label it as a proton‑donating substance and handle it as a strong acid. The Lewis perspective adds that the same HCl can also accept an electron pair from a base, such as water or a solvent, acting as a Lewis acid. Combining these ideas means the firm must recognize that the product can both donate protons (Arrhenius) and accept electrons (Lewis), affecting how it is stored, mixed, and labeled for safety. For example, a batch of HCl sold for industrial use must be kept in a container that resists protonation of the lining (Arrhenius) and also prevents unwanted electron‑pair reactions that could degrade the material (Lewis). This dual understanding helps the company design proper handling protocols and communicate risks accurately.

Detailed Explanation

An Arrhenius acid is a substance that, when dissolved in water, releases hydrogen ions (H⁺). Other options are incorrect because The idea that a Lewis acid must be solid and an Arrhenius base must be liquid is wrong; Saying both acids and bases must dissolve in water is incorrect.
