Final answer:
The bicarbonate ion is also known as the Hydrogen Carbonate ion. It is the hydrogen carbonate salt of carbonic acid and is commonly found in substances like baking soda.
Step-by-step explanation:
The ion that is also known as the "bicarbonate ion" is the Hydrogen Carbonate ion, option c.
The bicarbonate ion is the hydrogen carbonate salt of carbonic acid, H2CO3, in which one hydrogen atom has been replaced. It is an acid carbonate and is commonly found in substances such as baking soda. The chemical formula for the bicarbonate ion is HCO3-.
For example, when sodium bicarbonate (NaHCO3) is dissolved in water, it dissociates into sodium ions (Na+) and bicarbonate ions (HCO3-). This is what gives it its characteristic fizzing and leavening properties.
