To solve the question regarding which compound gives a purple color with neutral FeCl₃, we can follow these steps:1. Understanding FeCl₃: - FeCl₃ (iron(III) chloride) dissociates in solution to form Fe³⁺ ions
Silver acquires a black colour when exposed to air containing H2S due to the formation of silver sulphide on its surface. Based on the above paragraph, answer the following question. Why do we apply paint on iron articles? View Solution Metals get attacked by substances around it such as ...

To investigate the ability of Streptomyces strains in colour change of paintings, the Streptomyces strains were cultured on SNA plates supplemented with hematite (iron oxide) 0.02, 0.04 and 0.08% and incubated for 7 days at 30 °C. On the other hand, to investigate their ability to cause fadi...
sulphides, carbides, and nitrides. Compared with physicochemical methods, biogenic nanoparticle synthesis is more economical and environmentally friendly84. To enhance organic synthesis, efforts should be focused on developing eco-friendly nanosynthesis techniques and scaling up laboratory research to industria...
The bacteria belonging to the families of the Thiobacteriaceae, Beggiatoaceae and Achromatiaceae are commonly called the colourless sulfur bacteria. While
The photo-initiator, which is convertible by a photochemical reaction into a developer, is preferably an acylphosphine oxide or sulphide and/or a compound which generates acid when irradiated. The compound which generates acid when irradiated is preferably an onium salt, a latent sulphonic acid, a...
