Non-electrolyte

Definition

Non-electrolytes are substances that do not dissociate into ions when dissolved in water. They do not conduct electricity in aqueous solutions.

5 Must Know Facts For Your Next Test

1. Non-electrolytes include many organic molecules such as glucose and urea.
2. They play a role in osmoregulation by affecting the osmotic balance without altering ionic strength.
3. Unlike electrolytes, non-electrolytes do not contribute to the electrical conductivity of bodily fluids.
4. In biological systems, non-electrolytes can influence water movement across cell membranes via osmosis.
5. Understanding the behavior of non-electrolytes helps in comprehending their role in cellular processes and overall fluid balance.
