Caustic solutions are usually strong acids and/or bases.

Caustic solutions are usually strong acids and/or bases.

• A. Solvents
• B. Strong acids and/or bases
• C. Pigments
• D. Adhesives

Answer: (B)

Caustic describes a chemical’s ability to burn or corrode tissue or materials. In water, that corrosiveness comes from the substance dissociating to produce a high concentration of reactive ions. That’s what strong acids and strong bases do — they fully dissociate and create a highly reactive, corrosive environment. So caustic solutions are typically strong acids and/or bases because their power to cause chemical burns and damage comes from that complete ionization. The other options don’t capture this corrosive, reactive nature. Solvents are mainly about dissolving substances, pigments provide color, and adhesives are for bonding. None of those definitions describe caustic behavior, whereas strong acids and bases do.
