A. [tex]Al _2(SO _4)_3+ H _2 O[/tex]
B. [tex]Al _2(SO _4)_3+ CO _2+ H _2 O[/tex]
C. [tex]Al _2(SO _4)_3+ H _2[/tex]
Answer (2)
Aluminum reacts with sulfuric acid in a single displacement reaction.
The products of the reaction are aluminum sulfate and hydrogen gas.
The unbalanced chemical equation is A l + H 2 S O 4 → A l 2 ( S O 4 ) 3 + H 2 .
Therefore, the correct products are A l 2 ( S O 4 ) 3 and H 2 .
Explanation
Identifying the Reaction Type The reaction between aluminum (Al) and sulfuric acid (H2SO4) is a single displacement reaction. In this type of reaction, a more reactive metal displaces hydrogen from an acid.
Determining the Products In this specific case, aluminum reacts with sulfuric acid to produce aluminum sulfate and hydrogen gas. The unbalanced chemical equation is: A l + H 2 S O 4 → A l 2 ( S O 4 ) 3 + H 2
Choosing the Correct Products Comparing the equation with the given options, the correct products are aluminum sulfate ( A l 2 ( S O 4 ) 3 ) and hydrogen gas ( H 2 ).
Examples
This type of reaction is used in various industrial processes, such as the production of hydrogen gas or the synthesis of aluminum compounds. For example, if you want to produce hydrogen gas in a lab, you can react aluminum with sulfuric acid. The hydrogen gas can then be collected and used for other experiments or applications. This reaction also demonstrates the reactivity of metals and their ability to displace hydrogen from acids, a fundamental concept in chemistry.
The reaction between aluminum and sulfuric acid produces aluminum sulfate ( A l 2 ( S O 4 ) 3 ) and hydrogen gas ( H 2 ). The correct choice from the options provided is C. A l 2 ( S O 4 ) 3 + H 2 .
