Phenolphthalein Indicator 100gm, Merck

Phenolphthalein Indicator is a widely used pH indicator in titrations and various chemical analyses. It is colorless in acidic solutions and turns pink in basic (alkaline) environments, with the transition occurring around a pH range of approximately 8.2 to 10.0. This characteristic makes it particularly useful for identifying the endpoint of titrations involving strong bases, such as sodium hydroxide.

In addition to its use in titrations, phenolphthalein can be employed in laboratory experiments to assess the acidity or alkalinity of various solutions. It’s important to note that while it is a reliable indicator in many cases, it should not be used in situations where the pH is expected to fluctuate outside its effective range, as the color change may not be clear. Furthermore, phenolphthalein is often used in educational settings to demonstrate acid-base reactions due to its vivid color change, making it a staple in chemistry and biology labs.
