A base has more hydroxide (OH-) ions than a neutral solution. This is because bases generally release hydroxide ions when they dissociate in water.
Lye, containing hydroxide ions, is a base. Bases are substances that release hydroxide ions (OH-) in water solution.
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.
The kind of ion is an H+-ion, also called a proton.
A neutral solution has an equal concentration of H+ and OH- ions. At room temperature, this corresponds to a pH of 7 on the pH scale.
Copper(II) chloride (CuCl2) is not a base; it is a salt that is composed of copper(II) cations and chloride anions. It is an ionic compound that can dissociate in solution to form copper ions and chloride ions.

This type of reaction is called an acid-base reaction or neutralization reaction. It typically involves the transfer of protons (H⁺ ions) from the acid to the base, resulting in the formation of water and a salt. In these reactions, the properties of the acid and base are neutralized, leading to a solution that is closer to neutral pH.
A neutral solution has an equal concentration of H+ and OH- ions. At room temperature, this corresponds to a pH of 7 on the pH scale.
In a neutral solution, the number of hydronium ions (H₃O⁺) is equal to the number of hydroxide ions (OH⁻). This balance occurs at a pH of 7, which is typical for pure water at 25°C. In such solutions, the concentration of both ions is 1 × 10⁻⁷ moles per liter, maintaining equilibrium.

A base that only partly ionizes in a solution is considered a weak base. This means that only a small fraction of the base molecules will ionize to release hydroxide ions in the solution. Examples of weak bases include ammonia (NH3) and methylamine (CH3NH2).
A base alkali releases hydroxide anions (OH-) into the solution when it is dissolved in water. These hydroxide ions are responsible for the basic properties of alkalis, such as their ability to neutralize acids.
