Which statement about strong acids is true?

• A. They do not ionize in water.
• B. They produce the greatest concentration of H+ ions in solution.
• C. They produce OH- ions in solution.
• D. They are always weak reactants.

Answer: (B)

Strong acids ionize completely in water, meaning nearly every acid molecule donates a proton to water to form hydronium ions. Because the dissociation is complete, the hydronium ion concentration [H3O+] essentially equals the amount of acid added, giving the solution a very high [H+]. That’s why the statement about producing the greatest concentration of H+ in solution is true—it outstrips weaker acids that only partially ionize. Producing OH− ions is a property of bases, not acids, so that option is not correct. And strong acids are not weak reactants; they are strong electrolytes that fully dissociate in solution, so describing them as weak would be inaccurate.
