In acid, the nitrogen gets protonated making the chloride (if using hydrochloric acid) salt of aniline, which is soluble. In a basic solution, the nitrogen is not protonated, so the solubility is much lower.
Aqua regia (mixture of concentrated nitric acid and hydrochloric acid). However, nitric acid and hydrochloric acid by themselves don't dissolve gold.
Yes, hydrochloric acid can dissolve gold.
Yes, gold does not dissolve in hydrochloric acid.
Yes, hydrochloric acid can dissolve gold.
Barium sulfate is insoluble in hydrochloric acid. When mixed, it forms a white precipitate of barium chloride and remains as solid particles in the solution.

Yes, hydrochloric acid can dissolve gold.
Yes, gold does not dissolve in hydrochloric acid.
Yes, hydrochloric acid can dissolve gold.
A strong acid solution (hydrochloric acid or sulfuric acid for instance) will dissolve most metals.
Soluble in hydrochloric acid means that a substance is able to dissolve or mix into hydrochloric acid to form a homogeneous solution. This ability to dissolve indicates a chemical interaction between the substance and the acid.
Barium sulfate is insoluble in hydrochloric acid. When mixed, it forms a white precipitate of barium chloride and remains as solid particles in the solution.
The most common solution used to dissolve bamboo charcoal is acidic solutions, such as hydrochloric acid or nitric acid. These acids help break down the carbon structure of the charcoal, allowing it to dissolve.
One way to separate this mixture is through a process called liquid-liquid extraction. Aniline and benzoic acid are both water-soluble, while chloroform is not. By adding water to the mixture, the aniline and benzoic acid will dissolve in the water phase, leaving the chloroform to be separated out. The aniline and benzoic acid can then be recovered from the water phase by adjusting the pH of the solution.
Both being two polar compounds, aniline is highly soluble in acetic acid.
Yes, magnetite can dissolve in hydrochloric acid. When placed in hydrochloric acid, the iron component of magnetite reacts with the acid to form iron chloride, which results in the dissolution of magnetite.
