Crystalloidal and a Colloidal Solution: Difference | Colloids | Biology

To understand the difference between a crystalloidal and a colloidal solution, one should remember that the forces which keep the solute particles in solution are roughly as follows: (a) Inherent movement of the solute particles, i.e., their diffusibility. (b) Inherent movement of the solvent molecules which continuously dash against the solute particles and thus help to keep them in solution. [...]

Determination and Measurement of pH | Biophysics

In this article we will discuss about the determination and measurement of pH. Determination of pH: For routine work pH of a solution is determined with pH paper, and pH meter. I. pH Paper: pH papers of both broad and close ranges are available. Those are dispensed in reels. The colour of the paper changes with pH. The colours produced [...]

How to Prepare Buffers? | Biophysics

The following article will guide you about how to prepare buffers. Substances diminishing the change in pH, which would otherwise occur in the solution, are known as buffers. Chemical reactions are almost always associated with a change in pH in a solution. Variation in pH causes change in the reaction rate or velocity of reaction. The change in pH is [...]
