Extraction and Washing Guide - MIT OpenCourseWare

4) Washing the organic layer to remove impurities. The volume of a wash phase is typically one tenth to one half the volume of the organic phase. It is sometimes best to repeat a wash two or three times. An acid wash (usually 10% HCl) is used to remove amines, while a basic wash (usually sat. NaHCO3 or 10% NaOH) is used to remove unwanted acids. In most

Kinetic Theory and The States of ... - The Science Classroom

Kinetic molecular theory (also known as particle theory) states that all matter is made up particles and these particles are always in motion. Kinetic molecular theory is useful in describing the properties of solids, liquids and gases at the molecular level. We will describe these by their general motion and amounts of kinetic energy as follows.

The Physics Classroom Tutorial

To review, temperature is a measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. If two objects - or if a system and its surroundings - have a different temperature, then they have a different ability to transfer heat. Over time, there will be a flow of energy from the hotter object to the cooler …
