1. The substance to be analyzed – is white, highly soluble in water salt. When interacting with concentrated sulfuric acid – evolving of some odorless and colorless gas is observed. Reaction with diluted acids or NaOH solution doesn’t lead to any precipitation. Interaction with Nessler's reagent leads to formation of reddish-brown precipitate. Addition of barium chloride solution leads to appearance of white precipitate, which soluble in acetic acid. What kind of salt is this? Explain you answer, provide chemical equations
For the acidified chromate equilibrium, what effect would you predict if you diluted the system (meaning you add just pure water to a mixture that had been at equilibrium)?
