WebAcids (using the Arrhenius definition) are chemicals which produce H+ ions, while bases are chemicals which produce OH- ions. So when barium hydroxide (Ba(OH)2) and hydrochloric acid (HCl) enter a water solution they will dissociate, or split up. The barium hydroxide will split into one barium ion, Ba^(2+), and two hydroxide ions, OH-. Upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas: HNO3 + 3 HCl → NOCl + Cl2 + 2 H2O as evidenced by the fuming nature and characteristic yellow color of aqua regia. As the … Meer weergeven Aqua regia is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. Aqua regia is a fuming liquid. Freshly prepared aqua regia is colorless, but it turns yellow, orange or red within seconds … Meer weergeven Dissolving gold Aqua regia dissolves gold, although neither constituent acid will do so alone. Nitric acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold(III) ions (Au ).
