🧪 Neutral Solution
A neutral solution is one in which the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH−). This balance results in a solution that is neither acidic nor basic.
🔬 pH of a Neutral Solution
At room temperature (25°C), a neutral solution has a pH of exactly 7. The pH scale ranges from 0 to 14, with values lower than 7 indicating acidity and higher than 7 indicating alkalinity.
💧 Example:
Pure water (H2O) is a classic example of a neutral solution. It self-ionizes to produce equal amounts of H+ and OH− ions, maintaining a pH of 7 under standard conditions.
📌 Key Characteristics:
- Equal concentrations of H+ and OH− ions
- pH exactly 7 at 25°C
- Does not alter the color of universal indicators significantly
- Does not show typical acidic or basic properties
🧠Note:
If the temperature changes, the ionization of water changes slightly, so the pH at neutrality may shift. However, it is still considered neutral as long as the concentrations of H+ and OH− remain equal.
