A Study Of Distance Between Water Molecules

Abstract

In this research we study distance between water molecules by means simple laboratory mechanisms,   although hydrogen bond between each other is the strength bond between organic compounds molecules, water molecules are divergent. The alkanes like heptane and hexane have the weaker forces between its molecules, vandervals forces, though they are not divergent. Last two facts are supported by boiling points which indicate to strength of hydrogen bond, on the other hand we can dependence on density calculate the volume which occupied by one molecule in the liquid (one mole), and we can conformable this volume with that calculate according to molecule diameter. For molecules like hexane and heptane we  found correspondence, this means its molecules are not divergent, on the other hand water molecules where divergent. So to avoid doubt if water molecule is bigger than calculated theoretical, we must assure its molecule weight, we calculate the molecular weight experimentally from slow drying  the salt aqueous Sodium thiosulfate, slow drying was to avoid any decomposition  may happen at high temperature degrees. And we calculate dry salt concentration by titrate aqueous Sodium thiosulfate using Iodine I₂. All results assure the fact that water molecules are divergent, so the lonely explanation we found that there is electrical discord forces between protons balance with the strong hydrogen bonds between water molecules.
