Here's why:
* pH Scale: The pH scale measures the acidity or alkalinity of a solution. A pH of 7 is considered neutral.
* H+ and OH- Ions: In pure water, there is an equal concentration of H+ (hydrogen ions) and OH- (hydroxide ions). This balance results in a pH of 7.
* Equilibrium: The reaction between H+ and OH- ions is an equilibrium reaction, meaning it can proceed in both directions. In a neutral solution, the forward and reverse reactions occur at the same rate, maintaining the equal concentration of H+ and OH-.
Examples of neutral solutions:
* Pure water
* A solution with a pH of 7
