What is the formula for the ammonium ion?
What is the name for CN”?
What is the formula for the hydrogen sulfate ion?
The ion
The Correct Answer and Explanation is :
- Formula for the Ammonium Ion (NH₄⁺):
The ammonium ion is a positively charged polyatomic ion with the formula NH₄⁺. It consists of a nitrogen atom (N) covalently bonded to four hydrogen atoms (H), and it carries a +1 charge. This ion is formed when ammonia (NH₃) accepts a proton (H⁺), making it a base in acid-base reactions. - Name for CN⁻ (Cyanide Ion):
The formula CN⁻ represents the cyanide ion, and it is simply referred to as cyanide. It consists of a carbon atom (C) triple-bonded to a nitrogen atom (N), and it carries a negative charge. Cyanide is highly reactive and toxic and is known for its ability to bind to metal ions, particularly iron in hemoglobin, disrupting oxygen transport in the body. - Formula for the Hydrogen Sulfate Ion (HSO₄⁻):
The hydrogen sulfate ion, also known as bisulfate, has the formula HSO₄⁻. It is formed when sulfuric acid (H₂SO₄) loses one proton (H⁺), but still retains one hydrogen atom. The ion consists of a sulfate (SO₄²⁻) group bonded to a hydrogen ion (H⁺), making it negatively charged overall. The hydrogen sulfate ion is an intermediate species in the dissociation of sulfuric acid.
Explanation:
- Ammonium Ion (NH₄⁺): In a solution, the ammonium ion behaves as a weak acid. It can donate a proton (H⁺) to form ammonia (NH₃), making it an important species in buffer systems. Its structure allows for the hydrogen atoms to be arranged tetrahedrally around the nitrogen atom, similar to methane (CH₄).
- Cyanide Ion (CN⁻): Cyanide is highly toxic due to its ability to interfere with the electron transport chain in cellular respiration. The carbon and nitrogen atoms are connected through a strong triple bond, and the negative charge is localized on the nitrogen atom.
- Hydrogen Sulfate Ion (HSO₄⁻): The hydrogen sulfate ion is common in acid-base reactions involving sulfuric acid. Its conjugate base, the sulfate ion (SO₄²⁻), is formed after a second proton dissociates from sulfuric acid.
I will now generate an image to help visualize these ions.
Here is a visual representation of the ammonium ion (NH₄⁺), cyanide ion (CN⁻), and hydrogen sulfate ion (HSO₄⁻). It shows the molecular structure and charge distribution for each ion. Let me know if you’d like further details or explanations!
