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?
To group the white substances into two groups based on their properties, you need to consider their common characteristics. In this case, we can separate the substances into two groups - one that dissolves in water and another that has solubility in ethanol.
To determine which substances dissolve in water, you can use their solubility data. Solubility refers to the ability of a substance to dissolve in a particular solvent. If a substance dissolves in a particular solvent, it means it forms a homogeneous mixture with that solvent.
For the solubility in ethanol, you can refer to the same principle. Ethanol is the solvent, and if a substance dissolves in ethanol, it means it can form a homogeneous mixture with ethanol.
Now, let's apply this approach to the given substances:
Group 1: Substances that dissolve in water:
- Calcium carbonate: Insoluble in water
- Citric acid: Soluble in water
- Sucrose: Soluble in water
- Phenyl salicylate: Insoluble in water
Group 2: Substances with solubility in ethanol:
- Potassium iodide: Soluble in ethanol
- Sodium chloride: Insoluble in ethanol
The properties for each group are as follows:
Group 1 (Dissolves in water):
- Citric acid: Soluble in water
- Sucrose: Soluble in water
Group 2 (Solubility in ethanol):
- Potassium iodide: Soluble in ethanol
- Sodium chloride: Insoluble in ethanol
Remember, solubility may depend on various factors such as temperature, pressure, and concentration. The information provided here assumes standard conditions.
