Are the following ammonium compounds soluble in water?
| Compound | Solubility |
| :------- | :--------- |
| $NH _4 OH$ | |
| $NH _4 Cl$ | $\checkmark$ |
| $( NH _4)_2 O$ | $\checkmark$ |
| $NH _4 I$ | $\checkmark$ |
| $NH _4 Br$ | $\checkmark$ |
| $NH _4 NO _3$ | $\checkmark$
Answer (2)
Analyze the provided table to determine the solubility of ammonium compounds.
Observe that the solubility of N H 4 O H is not explicitly marked as soluble.
Conclude that the solubility of N H 4 O H is not specified based on the given information.
Therefore, the solubility of N H 4 O H is not specified in the table.
Explanation
Understanding the Problem We are given a table of ammonium compounds and their solubilities in water. Our task is to determine whether each compound is soluble based on the information provided in the table.
Analyzing the Table The table indicates the solubility of several ammonium compounds with a checkmark ( ✓ ) signifying solubility. We need to check the solubility of N H 4 O H .
Determining Solubility of N H 4 O H Looking at the table, we see that the solubility of N H 4 O H is not marked with a checkmark. This means its solubility is not explicitly stated as soluble in the table.
Conclusion Therefore, based on the provided information, we cannot definitively say that N H 4 O H is soluble.
Examples
Solubility is a crucial concept in chemistry and has many real-world applications. For example, when preparing solutions in a lab, it's important to know whether a compound will dissolve in a particular solvent. In environmental science, understanding the solubility of pollutants helps predict their movement and impact in water systems. In medicine, the solubility of drugs affects their absorption and distribution in the body. Knowing whether a compound is soluble helps in many practical applications.
Most of the ammonium compounds listed, such as N H 4 Cl , ( N H 4 ) 2 O , N H 4 I , N H 4 B r , and N H 4 N O 3 , are soluble in water. The solubility of N H 4 O H is not explicitly marked in the table, but it is typically considered soluble. Therefore, we are confident about the solubility status of these compounds except for N H 4 O H which is not confirmed in the table.
