Regolith is a layer of loose, heterogeneous superficial material covering solid rock. It includes dust, soil, broken rock, and other related materials and is present on Earth, the Moon, Mars, some asteroids, and other terrestrial planets and moons.n Earth, the presence of regolith is one of the important factors for most life, since few plants can grow on or within solid rock and animals would be unable to burrow or build shelter without loose material. Regolith is also important to engineers constructing buildings, roads and other civil works.
Aqua regia is a mixture of nitric acid and hydrochloric acid. The mixture is formed by mixing concentrated nitric acid and hydrochloric acid, optimally in a volume ratio of 1:3. Aqua regia was named so because it can dissolve the noble metals gold and platinum.xperimental evidence reveals that the reaction of platinum with aqua regia is considerably more complex. The initial reactions produce a mixture of chloroplatinous acid (H 2 PtCl 4) and nitrosoplatinic chloride ((NO) 2 PtCl 4). The nitrosoplatinic chloride is a solid product.
