Chemistry I Monday, September 26, 2016- Chapter 4 Reactions in Aqueous Solutions Solution can contain gas, solid, or liquid Solvent is the product most condensed in the solution Solute are the less condensed products within a solution Solvents+ solutions = aqueous solution Dissociation= ionic compounds + H O 2ater + ions Molecular compounds + water = molecular compounds dissolved + water SO LET ME TELL YOU: When Ionic compounds mix with water, the positive and negative ions attract to one another, contains energy within.creating a (+-) creating ions. Cations (+) Anions (-) Electrolytes: turns in ions when in water, so basically like an ionic compound. Nonelectrolyte: will mix with water but not dissociate. Strong acids are strong enough to dissociate in water. (Strong electrolyte) Weak acids are similar to a non-electrolyte. (Weak electrolyte) Strong electrolyte: dissociates in water Weak electrolyte: ½ dissociates ½ does not Nonelectrolyte: does not dissociate Chemical equilibrium “⇌” : rreaction can go both ways can only go from left to right, in this case can go from reactant to product PRECIPITATION RULES: When one salt solution + one salt solution =(sometimes) an insoluble salt = (a precipitate) Precipitate is formed when opposite ions attach so strongly produce a precipitate. (the ions are like madly in love and join together and then create a little baby called precipitate) Solubility is a value of how much a substance can be dissolved in a amount of solvent at a specific temperature. NOT ALL IONIC COMPOUNDS DISSOLVE SOLUBILITY DEPENDS ON THE MODD THE WATER IS AND IF IT WANTS TO INTERACT WITH THE IONS, YOU KNOW HOW WATER CAN BE MOODY. Wednesday, September 28, 2016 – Review Test
