The magnesium sulphate would readily yield sulphuric acid, which with sodium chloride and nitre, might be expected to produce aqua regia; (for further information see under "rasakarpúra" or the chlorides of mercury). - [Previous: v1.c19.5](https://indike.org/pramana/ins.science.ray-1902.v1.c19.5) - [Next: v1.c19.7](https://indike.org/pramana/ins.science.ray-1902.v1.c19.7) - [Up: v1.c19](https://indike.org/pramana/ins.science.ray-1902.v1.c19) --- Source: [https://indike.org/pramana/ins.science.ray-1902.v1.c19.6](https://indike.org/pramana/ins.science.ray-1902.v1.c19.6) · Pramāṇa
