Acids:
* Donate protons (H+): Acids are substances that release hydrogen ions (H+), also known as protons, when dissolved in water.
* Increase H+ concentration: The presence of more protons in solution makes the solution more acidic.
Bases:
* Accept protons (H+): Bases are substances that accept protons (H+) when dissolved in water.
* Decrease H+ concentration: Bases remove protons from solution, making the solution less acidic (more basic).
Mixing Acids and Bases:
* Neutralization reaction: When an acid and a base react, they undergo a neutralization reaction. This is a process where the acid's protons (H+) react with the base's hydroxide ions (OH-) to form water (H2O).
* Example: HCl (acid) + NaOH (base) -> NaCl (salt) + H2O (water)
* pH change: The addition of an acid to a base (or vice versa) results in a change in the pH of the solution.
* Acid + Base -> More Neutral pH : If the acid and base are in equal amounts, they neutralize each other, resulting in a neutral solution with a pH close to 7.
* Excess Acid -> Lower pH: If there's an excess of acid, the solution will remain acidic with a lower pH.
* Excess Base -> Higher pH: If there's an excess of base, the solution will become more basic with a higher pH.
Key Points:
* Protons are the key players in acid-base reactions.
* Acids donate protons, bases accept them.
* Neutralization is a process where protons and hydroxide ions combine to form water.
* The pH of a solution reflects the concentration of protons.
