Final answer:
Strong acids and strong bases can coexist in solutions. Examples of strong acids include hydrochloric acid (HCl) and sulfuric acid (H2SO4), while examples of strong bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
Step-by-step explanation:
Strong acids and strong bases can coexist in solutions.
In aqueous solution, a strong acid dissociates into hydrogen ions (H+) and anions, producing a high concentration of H+. Similarly, a strong base dissociates into hydroxyl ions (OH-) and cations, producing a high concentration of OH-. Therefore, both strong acids and strong bases exist as ions in solution.
Examples of strong acids include hydrochloric acid (HCl) and sulfuric acid (H2SO4), while examples of strong bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
