What does selectively permeable mean?

A selectively permeable membrane is a material that is able to allow specific materials to pass through it while stopping other materials. In other words, it can stop substances that are larger than a certain size from passing through it.

What does selectively permeable mean in English?

The word “selectively” in the phrase “selectively permeable” refers to a property of a material that allows some things to pass through it while rejecting others. The two main types of selectively permeable materials are porous and permeable. Porous materials contain spaces between their particles. A porous concrete will allow water through its pores, but it won’t allow oil, so it’s a good material for building a septic tank. A permeable material

What does selectively permeable mean in science?

A selectively permeable material allows some substances to pass through it, while keeping others out. A porous rock, for example, may be permeable to water, but not to sand. Water can pass through the pores in the rock, but the sand is stopped by the rock’s structure.

What does selectively permeable mean in Spanish?

The word “selectively” refers to the ability to allow or prevent the flow of particular substances through a membrane.

What does selectively permeable mean in chemistry?

A selectively permeable material allows some substances to pass through it, while keeping others out. For example, porous materials are often selectively permeable. This allows water to pass through the material while keeping other liquids from passing through. Other materials, like some membranes, are selectively permeable to certain ions, like potassium or chloride.
