CHEMICAL PROPERTIES OF SOLUTIONS INCREASE DOWN POINT Boiling occurs because heat increases motion or kinetic energy, from molecules that cause fluid to exist at the point where the liquid evaporates, regardless of being on the top surface or in the deepest part of the liquid When a solution has a high vapor pressure at a certain temperature, then the molecules within the solution are easy to escape from the surface of the solution. Or it can be said that at the same temperature a solution has a low vapor pressure, then the molecule molecules in the solution can not easily escape from the solution. So a solution with a higher vapor pressure at a certain temperature will have a boiling point The lower one. The liquid will boil when the vapor pressure becomes equal to the outside air pressure. Liquid boiling point at air pressure 760 mmHg is called the standard boiling point or normal boiling point. So what is meant by the boiling point is the temperature at which the saturat...

Predicted The Product Of Chemical Reaction To write a simple document, some reliable rules are needed to assess the direction of a chemical reaction. And this judgment depends on several factors. 1. If free energy is known, there is no problem in prediction. 2. If only known enthalpy changes, predictions usually apply to ordinary temperatures are cheaper reliable for higher temperatures. 3. If any of them can be affected, the prediction is relatively simple and potential can be overcome in the possibility of reaction in the absence of solvent. 4. If the equilibrium constant is known, the relationship, G = - RH ln K gives free energy change, or reaction at ordinary temperatures where the entropy changes are not expected to be large, its relative strength in the reactants and the product can be estimated as a guide for the course of the reaction. On this basis, we may use this rule: Principle 1 : chemical reactions that occur with the bonds of electrons and electrons t...
