Which element is necessarily present in all acids?
Answer: C. Hydrogen
Explanation:
Acids are substances that release hydrogen ions (H+) when dissolved in water. Therefore, hydrogen is necessarily present in all acids. Here is a detailed explanation:
Definition of an Acid:
An acid is a substance that donates hydrogen ions (H+) or protons in a chemical reaction.
Characteristics of Acids:
1. Acids have a sour taste.
2. Acids turn blue litmus paper red.
3. Acids react with metals to produce hydrogen gas.
4. Acids react with bases to form salts and water.
5. Acids have a pH value less than 7.
Explanation of the Necessity of Hydrogen in Acids:
1. Acids are defined by their ability to donate hydrogen ions (H+). When an acid dissolves in water, it releases these hydrogen ions, which are responsible for the acidic properties.
2. The presence of hydrogen ions is what gives acids their characteristic sour taste, ability to turn litmus paper red, and low pH value.
3. Without hydrogen, a substance cannot exhibit the properties of an acid.
Other Elements in Acids:
While hydrogen is necessarily present in all acids, other elements may also be present. Some common examples include:
