The definition you provided is known as the Arrhenius definition of acids and bases. According to this definition, an acid is a substance that donates H+ ions in solution, while a base is a substance that donates OH- ions in solution. This concept helps explain the behavior of acids and bases in aqueous solutions.
An acid is a chemical compound that donates hydrogen ions to a solution. This process increases the concentration of hydrogen ions in the solution, lowering its pH.
Increases as the acid donates H+ ions to react with the base to form water, resulting in an increase in the concentration of OH- ions in the solution.
A base is a compound that produces hydroxide ions (OH-) in solution.
neutral
An acid donates an H+, and a base donates an OH-.
Bases produce hydroxide ions (OH-) in solution. When a base dissolves in water, it donates hydroxide ions, which can then react with acids to neutralize them and form water.

A substance that does not form hydroxide ions in water but donates protons is considered an acid, not a base. Bases are substances that release hydroxide ions in water.
An acid is a chemical compound that donates hydrogen ions to a solution. This process increases the concentration of hydrogen ions in the solution, lowering its pH.
A base substance forms hydroxide ions (OH-) in water. This occurs when the base substance donates OH- ions to the water molecules, increasing the concentration of hydroxide ions in the solution.
Dissociation of a base produce hydroxyl ions.
This is the definition of a base.
Hydronium ion, H3O+, is what gives a low pH to an aqueous solution. Hydronium ion is made when an acid donates a hydrogen ion to a water molecule. Hydroxide ion, OH-, gives a higher pH to an aqueous solution. Hydroxide ions are found in bases; a base donates hydroxide ions to water. Combining H3O+ + OH- makes 2 H2O. In other words, an acid and a base combine to neutralize each other as water.
Increases as the acid donates H+ ions to react with the base to form water, resulting in an increase in the concentration of OH- ions in the solution.
In water solutions an acid or a base is diluted depending on the amount of water. But when water is added with an acid or base it also undergoes a condition called chemical equilibrium. For more information on chemical equilibrium check some more wikianswers or look it up on google :L
KOH (potassium hydroxide) is a base, while HNO3 (nitric acid) is an acid. In solution, KOH dissociates to release hydroxide ions, which can accept protons. HNO3 donates a proton to form hydronium ions in solution, making it an acid.
