Document Summary
Aqueous solution the solution where water is the dissolving medium. Solution when two or more substance are mixed together (homogeneous) Solvated when an ionic compound dissolves and the ions become surrounded by. Solvation helps to stabilize the ions in a solution and prevents the cations and anion from recombining. Weak electrolytes exists mostly as a neutral molecule with only some forming of ions. Means the reaction is significant in both directions. Chemical equilibrium the number of ions/molecules in a reaction are consistent over time. Precipitation reactions reactions that result in the formation of an insoluble product. Forms when two oppositely charged particles attract to each other so strongly that they form an insoluble ionic solid. Solubility the amount of the substance that can be dissolved in a given quantity of solvent at a certain temperature. Pb(no3)2 (aq) + 2ki(aq) pbi2(s) + 2kno3(aq) (aq) + 2k+(aq) + 2i-(aq) pbi2(s) + 2k+(aq) + 2no3.
