How can I group white substances into 2 groups according to their properties&list the properties of each group?
Calcium carbonate, citric acid, sucrose, Phenyl salicylate, Potassium iodide,and Sodium chloride
Also, which of them dissolves in water and which has solubility in ethanol?
look at solubility, and melting point as properties.
To group the white substances into 2 groups according to their properties, we should analyze their properties individually and then categorize them.
1. Calcium carbonate:
- It is insoluble in water.
- It does not dissolve in ethanol.
2. Citric acid:
- It is soluble in water.
- It does not dissolve in ethanol.
3. Sucrose:
- It is soluble in water.
- It is insoluble in ethanol.
4. Phenyl salicylate:
- It is insoluble in water.
- It is soluble in ethanol.
5. Potassium iodide:
- It is soluble in water.
- It does not dissolve in ethanol.
6. Sodium chloride:
- It is soluble in water.
- It does not dissolve in ethanol.
Based on these properties, we can group them as follows:
Group 1:
- Calcium carbonate (insoluble in water and ethanol)
- Phenyl salicylate (insoluble in water, soluble in ethanol)
Group 2:
- Citric acid (soluble in water, insoluble in ethanol)
- Sucrose (soluble in water, insoluble in ethanol)
- Potassium iodide (soluble in water, insoluble in ethanol)
- Sodium chloride (soluble in water, insoluble in ethanol)
So, the properties of each group are:
Group 1:
- Insoluble in water and ethanol
Group 2:
- Soluble in water, insoluble in ethanol
