Questions & Step-by-Step Solutions

If 0.1 M of a strong acid is mixed with 0.1 M of a strong base, what will be the resulting pH?
  • Step 1: Understand that a strong acid completely dissociates in water, meaning it releases all of its hydrogen ions (H+).
  • Step 2: Recognize that a strong base also completely dissociates in water, releasing all of its hydroxide ions (OH-).
  • Step 3: When you mix a strong acid with a strong base, the H+ ions from the acid react with the OH- ions from the base.
  • Step 4: This reaction produces water (H2O), which is neutral.
  • Step 5: Since the strong acid and strong base are both 0.1 M, they will completely neutralize each other, resulting in no excess H+ or OH- ions.
  • Step 6: The resulting solution will have a pH of 7, which is neutral.
  • Neutralization Reaction – The reaction between a strong acid and a strong base results in the formation of water and a salt, typically leading to a neutral pH.
  • pH Scale – Understanding the pH scale, where a pH of 7 indicates a neutral solution.
