Slaked lime is commonly used as a pH-regulating agent and acid neutralizer in soil and water. It is also known as calcium hydroxide or hydrated lime.
Slaked lime is applied to acidic soils to regulate the soil's pH levels. This allows for faster growth of crops by aiding the intake of nutrients and nitrogen by vegetation growing in the soil. It helps preserve stored fruits and vegetables when placed nearby in bags. The bags absorb carbon dioxide emitted by the fruits and vegetables, regulating oxygen levels which prolongs their freshness.
Calcium hydroxide is also used as a filler material in rubber and plastics, serving as an accelerator in the rubbers.
