Phenol red is a stable red crystal & Its chemical formula is C19H14O5S and it is also known as phenolsulfonphthalein or PSP. This substance acts as a pH indicator dye, meaning it changes color depending on the acidity or alkalinity of a solution. Below a pH of 6.8, it takes on a yellow color, while between 6.8 and 8.2 pH, it transitions to an orange to red hue. Above a pH of 8.2, it turns pink to fuchsia. Typically, phenol red is supplied in a diluted form, specifically a 0.02% solution. At this concentration, it appears as a red liquid and is usually stored in a neutral or slightly basic aqueous solution. Due to its properties, phenol red 0.02% solution is commonly utilized as a chemical indicator in various scientific applications.
