Ionic Conduction

Science > Chemistry > Electrochemistry > Ionic Conduction The conductance of an ion depends on its size in an aqueous medium or in the solvent. Bigger is the ionic size lesser is its conductance Example: The order of size of hydrated ionic radii of alkali metal cations is as Li+(aq) < Na+(aq) < K+(aq)< Rb+(aq)< Cs+(aq). Hence the ease […]

No Comments on White Blood Corpuscles (Leucocytes)

In this article, we are going to study another important component of blood plasma i.e. White blood corpuscles, their types, structures, and functions. They are colourless, nucleated, amoeboid (irregular shape) and phagocytic cells larger than RBC’s. Their size ranges from 12 μm to 20 μm. They have mitochondria, Endoplasmic reticulum, Golgi complex, ribosomes, and centrioles. […]
