Show Solution
The Correct Option is D
Solution and Explanation
The question is about identifying the correct chemical formula for calcium chlorite. To solve this, we need to understand the composition of calcium chlorite.
Calcium chlorite is an ionic compound formed from calcium ions and chlorite ions. Let's break this down:
- Calcium (Ca): The calcium ion has a charge of +2.
- Chlorite (ClO2-): The chlorite ion has a charge of -1.
In an ionic compound, the total positive charge must balance the total negative charge. Since calcium has a charge of +2 and chlorite has a charge of -1, we need two chlorite ions to balance one calcium ion. Therefore, the formula for calcium chlorite is Ca(ClO_2)_2.
Let's evaluate the given options:
- Ca(CIO_4 )_2: This is calcium perchlorate, not chlorite.
- Ca(CIO_3 )_2: This is calcium chlorate, not chlorite.
- CaCIO_2: This does not represent the proper stoichiometry to balance charges between calcium and chlorite.
- Ca(CIO_2 )_2: This is the correct formula for calcium chlorite, balancing the charges appropriately.
Hence, the correct answer is Ca(CIO_2 )_2, which reflects the correct stoichiometry and structure of calcium chlorite.
