The hydroxide ion, OH-, is present in all basic solutions. It is responsible for the characteristic properties of basic solutions, such as a bitter taste, slippery feel, and ability to turn litmus paper blue.
The OH- ion, also known as the hydroxide ion, is responsible for creating a basic solution when it is present in water.
Aqueous solutions of alkali metal carbonates are basic because they undergo hydrolysis in water, producing hydroxide ions that increase the pH of the solution. The carbonate ion reacts with water to form a hydroxide ion and bicarbonate ion, effectively raising the concentration of hydroxide ions in the solution and making it basic.
Hydroxide ion (OH-) is typically responsible for making a solution basic. When hydroxide ions are present in water, they combine with hydrogen ions to form water molecules, reducing the concentration of hydrogen ions and increasing the pH of the solution.
It is not available under normal conditions.
No, all salts do not form neutral solutions with water. The pH of the solution formed by a salt depends on the combination of the cation and anion present in the salt. Salts that contain a cation or anion that is acidic or basic can result in acidic or basic solutions when dissolved in water.
