What are acids and bases according to Arrhenius?

According to Arrhenius, acids are substances that release hydrogen ions (H+) in aqueous solutions, while bases are substances that release hydroxide ions (OH-) in aqueous solutions. Acids increase the concentration of H+ ions, whereas bases increase the concentration of OH- ions.


What elements produce hydrogen gas with ammonium hydroxide?

When ammonium hydroxide reacts with a metal, such as magnesium or zinc, it can produce hydrogen gas. The metal displaces the ammonium ion in ammonium hydroxide, forming the metal hydroxide and releasing hydrogen gas in the process.


Is barium hydroxide aqueous or solid?

Barium hydroxide is typically encountered as a solid at room temperature. However, it can dissolve in water to form a barium hydroxide solution, which is referred to as aqueous barium hydroxide. In its solid form, barium hydroxide appears as a white crystalline substance. When dissolved in water, it can produce a strongly alkaline solution.
