What is an example of like dissolves like?

What is an example of like dissolves like?

“Like dissolves like” is an expression used by chemists to remember how some solvents work. It refers to “polar” and “nonpolar” solvents and solutes. Basic example: Water is polar. Like dissolves like, that means polar dissolves polar, so water dissolves salt.

How does like dissolves like work?

The solubility of organic molecules is often summarized by the phrase, “like dissolves like.” This means that molecules with many polar groups are more soluble in polar solvents, and molecules with few or no polar groups (i.e., nonpolar molecules) are more soluble in nonpolar solvents.

What is the rule like dissolves like used to predict?

Polarity. A popular saying used for predicting solubility is “Like dissolves like.” This statement indicates that a solute will dissolve best in a solvent that has a similar chemical structure; the ability for a solvent to dissolve various compounds depends primarily on its polarity.

Which of the following statements best describes the rule like dissolves like?

Which of the following statements best describes the phrase “like dissolves like”? A solvent will dissolve a solute that has a similar mass. The only true solutions are formed when water dissolves a nonpolar solute. A solvent and a solute with similar attractive forces will easily make a solution.

Why is the process of dissolution important?

Dissolution is important for health practitioners because, for drugs to be absorbed and have a physiological effect in the human body, they must be in solution. For solid preparations, such as tablets and suppositories, the rate of dissolution affects how fast a drug is absorbed in the body.

Why does like dissolve like chemistry?

Chemists say that ‘like dissolves like,’ meaning that substances with similar chemical characteristics will dissolve in each other. Specifically, polar solvents tend to dissolve polar solutes, and non-polar solvents tend to dissolve non-polar solutes, while non-polar and polar substances are Immiscible (do not mix).

When two polar liquids are combined?

When another polar liquid such as ethanol is mixed with water, they completely blend and dissolve into one another. Liquids that dissolve in one another in all proportions are said to be miscible . Liquids that do not dissolve in one another are called immiscible .

Which of the following is a property of a true solution?

A true solution is a homogeneous mixture with uniform properties throughout. Particle size of solvent is less than 1nm. Particles of true solutions cannot be filtered through filter paper and are not visible by naked eyes. In true solution the particle size of solute is about the same as that of the solvent.

What is meant by the term like dissolves like?

“Like dissolves like” is an expression used by chemists to remember how some solvents work. It refers to “polar” and “nonpolar” solvents and solutes . Basic example: Water is polar. Oil is non polar. Water will not dissolve oil. Water is polar.

How does like dissolves like mean?

Like dissolves like basically means that a solute will dissolve well in a solvent that has a polarity quite similar t its own. This facilitates the dissolution process; this is helpful as it provides a rough idea about which solute will dissolve in which solvent.

What is the like dissolves like theory?

Like Dissolves Like. A simple way to predict which compounds will dissolve in other compounds is the phrase “like dissolves like”. What this means is that polar compounds dissolve polar compounds, nonpolar compounds dissolve nonpolar compounds, but polar and nonpolar do not dissolve in each other.

Why does like dissolves like?

“Like dissolves like” works because when polar molecules of solute and polar molecules of solvent interact, mixing can occur. “Like dissolves like” works because when molecules of solute and molecules of solvent have similar molecular formulas, mixing can occur.
