As hibiscus flower contains the colour pigment anthocynanin, not only can it be used as a natural indicator, it can also be used to produce natural dye that is eco-friendly and safe on human skin. Acid-base indicators are chemicals used to determine whether an aqueous solution is acidic, neutral, or alkaline. Because acidity and alkalinity relate to pH, they may also be known as pH indicators. Examples of acid-base indicators include litmus paper, phenolphthalein, and red cabbage juice.
