Explanation

Acetic acid (CH3COOH) is a weak acid that only partially dissociates in water, forming a weak electrolyte solution.

It does not fully dissociate into ions like strong acids (like HCl) or strong bases (like KOH).

Explanation

Silver nitrate (AgNO3) is a strong oxidizing agent and a caustic substance.

It is also known as "lunar caustic" due to its historical use to treat lunar burns (sunburn).

Explanation

Carbon dioxide (CO2) reacts with calcium hydroxide (Ca(OH)2.

It is also known as lime water to form a white precipitate of calcium carbonate (CaCO3), which turns the solution milky:

Ca(OH)2 + CO2 → CaCO3 + H2O

This reaction is often used as a test for carbon dioxide.

Explanation

Chlorine (Cl) is a strong oxidizing agent.

It means it can accept electrons from other substances and cause them to be oxidized.

Explanation

Selenium (Se) is a metalloid, which means it exhibits some properties of metals and some properties of nonmetals.

Metalloids are elements that are intermediate in character between metals and nonmetals.
