Here's a breakdown:
* Hydroxide Ions (OH-): Bases contain hydroxide ions, which are negatively charged ions consisting of one oxygen and one hydrogen atom. These ions are responsible for the characteristic properties of bases, such as their ability to neutralize acids.
* Reaction with Water: Some substances are not inherently bases but become bases when they react with water. These substances are called bases. When these substances dissolve in water, they produce hydroxide ions through a chemical reaction.
Examples of Bases:
* Sodium hydroxide (NaOH): A strong base that readily dissolves in water to produce hydroxide ions.
* Calcium hydroxide (Ca(OH)2): A strong base that is commonly used in cement and plaster.
* Ammonia (NH3): A weak base that reacts with water to form ammonium ions (NH4+) and hydroxide ions.
Key Properties of Bases:
* Bitter taste
* Slippery feel
* Ability to neutralize acids
* pH greater than 7
