Understanding pH and Acids

Easy General Chemistry Acids And Bases

Acids and bases are fundamental concepts in chemistry, with applications in various biological systems. Consider a solution with a pH of 3. This solution is highly acidic. When a base is added to this solution, the pH changes, reflecting the neutralization reaction that occurs between the acid and the base.

Which of the following statements is true regarding the relationship between acids, bases, and pH?

A solution with a pH greater than 7 is acidic.

All acids, when dissolved in water, increase the concentration of hydroxide ions (OH-).

A solution with a pH of 7 is considered neutral.

Adding a strong base to an acidic solution will lower the pH.
