Chapter 5: Problem 55

In general, oxyacids contain a nonmetal, oxygen, and what other element?

Short Answer

Expert verified
In general, oxyacids contain a nonmetal element, oxygen (O), and hydrogen (H) as the other element.

Step by step solution

01

Identify the common element for oxyacids

In oxyacids, we know that there's always a nonmetal element and oxygen. By analyzing the examples (H鈧係O鈧�, HNO鈧�, H鈧働O鈧�), we can notice that hydrogen (H) is a common element in all oxyacids.
02

Confirm the presence of hydrogen in other oxyacids

To be sure about our observation, let's consider some additional oxyacids: carbonic acid (H鈧侰O鈧�), chloric acid (HClO鈧�), and bromic acid (HBrO鈧�). In all of these examples, hydrogen is present along with a nonmetal element and oxygen.
03

Conclusion

Based on our observations of multiple oxyacid examples, we can conclude that in general, oxyacids contain a nonmetal element, oxygen (O), and hydrogen (H) as the other element.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Nonmetals in Chemistry
Nonmetals play an important role in the formation of oxyacids. They are elements that usually lack metallic properties and tend to have high electronegativities. This allows them to readily combine with oxygen to form oxo groups in molecules. Nonmetals can be found on the right side of the periodic table.
Examples of nonmetals include sulfur, nitrogen, phosphorus, chlorine, and bromine. These elements are crucial in forming oxyacids like sulfuric acid (\(H_2SO_4\)), nitric acid (\(HNO_3\)), and phosphoric acid (\(H_3PO_4\)).
  • Sulfur: Used to form sulfuric acid, an important chemical in manufacturing.
  • Nitrogen: Combines with oxygen to form nitric acid, used in fertilizers.
  • Phosphorus: Involved in phosphoric acid, used in food and beverage industry.

Oxyacids are typically composed by the nonmetal element bonded to one or more oxo groups, and this configuration is key to their acidic properties.
Chemical Composition of Acids
At the heart of understanding oxyacids is grasping their chemical composition. Oxyacids typically consist of three elements: a nonmetal, oxygen, and hydrogen. The nonmetal is central and usually bonded to several oxygen atoms which collectively form oxo groups.
  • Nonmetal: Acts as the central atom, it's the backbone of the acid molecule.
  • Oxygen: Bonds with the nonmetal, forming oxo groups which are vital for the acid's characteristics.
  • Hydrogen: Often attaches to an oxygen to form the carboxylic group (-OH), contributing to acidity.

The presence of the oxo groups is what typically gives the acid its acidic properties, as breaking this bond during dissociation releases hydrogen ions \( (H^+) \). This contributes to the acidic nature observed in solutions of oxyacids.
Hydrogen in Acids
Hydrogen is a cornerstone element in the structure of oxyacids. Its role is crucial in defining the acidic properties of these compounds. In chemistry, acids are recognized by the presence of hydrogen capable of being released as a proton \( (H^+) \).
In the case of oxyacids, hydrogen is attached to an oxygen atom, forming a hydroxyl group \((-OH)\). When the oxyacid dissolves in water, this hydrogen is released, rendering the solution acidic.
  • Hydrogen release: Key to the acid's ability to donate protons.
  • Hydroxyl group formation: Connects with the nonmetal's oxo group in the structure.
  • Acidity: The ability to release \(H^+\) ions upon dissociation.

Therefore, when examining oxyacids, the presence of hydrogen is not only necessary but instrumental in their function and behavior in chemical reactions.
