Frequently Asked Questions
Why do acidic soils require lime for neutralization?
Lime (calcium carbonate) is a base that neutralizes acidic soils by raising their pH to make them suitable for plant growth.
How is salt produced industrially from seawater?
Salt is produced by evaporating seawater, which leaves behind solid sodium chloride crystals.
