4 Solubility Equilibrium- Common Ion Effect INTRODUCTION: The common ion effect is another example of Le Châtelier ’s Principle in action.The common ion effect tells us that the solubility of an ionic compound is decreased by the addition to the solution of another ionic compound that contains one of the ions involved in the solution It is also responsible for the reduction in solubility of an ionic precipitate when a soluble compound combining one of the ions of the precipitate is added to the

hydrogen chloride has properties: Hydrogen chloride has one molecule of hydrogen and one molecule of chlorine: Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because

right because the removal of a component causes the equilibrium to shift to the side from which the component was removed. D. Is this reaction endothermic or exothermic? How do you know? When acid is added to water the reaction is strongly exothermic. Because the hydrogen ion is so tiny‚ a large amount of charge is concentrated in a very small

more efficient sources of power. At the forefront of research for these power sources are hydrogen fuel cells. This power source takes in the most abundant element in the universe‚ Hydrogen‚ and yields immense power without combustion or pollution. The three aspects of this scientific breakthrough are the fuel cells‚ hydrogen production‚ and hydrogen storage. Fuel cells are the devices with which Hydrogen is made into electricity. These use a technology much similar to that of something we are

that way if you believe in the power of change. Hydrogen fuel is that change for the automobiles of the future. Hydrogen has been used for decades‚ but mostly for commercial use. Each year‚ we get closer to removing the oil company’s choke hold on our wallets. It’s time to drive with a lighter purse and a cleaner environment and it’s time for hydrogen fuel. The two largest points of debate with hydrogen fuel are cost and production Hydrogen fuel is a cheaper alternative to our current source
