احصل على السعر· Sulphuric acid does not directly contain calcium required to replace the Na+ ions in the soil. Hence, it is only effective in calcareous soils (rare in the ), where it can react with the calcium carbonate to free the calcium already in place. Calcium carbonate (CaCO3), or lime, is alkaline and significantly less soluble than gypsum.
