Bases are ionic compounds that produce negative hydroxide (OH-) ions when dissolved in water.
- A "strong base" is a compound that has the ability to remove a proton from a very weak acid.
- They completely dissociate into its ions when in water.
- The strong bases are known as Alkali.
- pH value of bases are more 7.
Acids: An acid is a hydrogen-containing substance capable of donating a proton (hydrogen ion) to another substance.
- Acidic substances are usually recognized by their sour taste.
- It can turn blue litmus paper red.
- The pH value of acids are less than 7.
Carbon dioxide(CO2): Carbon dioxide is a chemical element that can be found in the atmosphere.
- It is found in the gaseous state at room temperature.
- It contains one atom of carbon and two atoms of oxygen.
- CO2 itself is not an acid, because it does not contain hydrogen ions (H+), but when dissolved in water, it becomes carbonic acid.
- Some carbon dioxide dissolves in water to form carbonic acid which acidifies the solution.
- Carbonic acid (H2CO3) is a weak, H+-splitting acid.
