What is miscible with water?
Miscible is a fancy word for "mixable." You may have heard that oil and water are not very miscible substances, whereas seltzer and orange juice are miscible and delicious! Miscible is a word used by chemists to explain why some liquids mix together well, while others do not.
Acetone's dipole moment is 2.91D while that of ether is only 1.15D. Water is a very polar substance, so acetone will dissolve in it while ether will not. If A and A have much stronger attraction than A and B the substances are less likely to be miscible.
- Water is polar in nature while Ether is non-polar. Ethers are very slightly soluble in water at around 6.8g/100g. This is due to the presence of oxygen in ethers which interact with hydrogen in water to produce H-bonding to make it slightly soluble. However, dimethyl ether is not at all soluble in water.
- The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent.
- A distinct layer between two liquids will not form when you have a solution that is labeled miscible. When a distinct layer does form in a mixed solution, this is called immiscibility. For example, a type of immiscible liquid is oil and water.
When a distinct layer does form in a mixed solution, this is called immiscibility. For example, a type of immiscible liquid is oil and water. When mixed together, oil will essentially 'sit on top' of water, resulting in the formation of a very noticeable layer.
- Miscible implies that liquids mix to form a homogeneous mixture in all proportions. Immiscible is defined as the opposite, they don't mix. Water is miscible in a variety of liquids, but immiscible in oil.
- Isopropyl alcohol is miscible in water, ethanol, ether, and chloroform. It will dissolve ethyl cellulose, polyvinyl butyral, many oils, alkaloids, gums and natural resins. Water-isopropyl alcohol mixtures have depressed melting points. It has a slightly bitter taste, and is not safe to drink.
- Mixtures of liquids can be separated according to their properties. The technique used depends on whether the liquids dissolve in each other, and so are miscible, or if they are immiscible. Fractional distillation is a technique used to separate liquids according to their boiling points.
