When producing orthophosphoric acid (H3PO4) via the wet process involving strong sulfuric acid leaching, how does it compare to the electric furnace method?

Explanation

The wet process using strong sulfuric acid results in orthophosphoric acid of lower purity compared to the electric furnace technique. While it may use lower-grade phosphate rock and require less capital investment, the main distinction lies in the acid's purity, which is inferior in the wet process.
