state of saturation. This can be recognised by a constant colour or constant mass. The solubility product constant‚ Ksp is given in the following example: Ksp for AgCl is Ksp = [Ag][Cl] Ksp for PbI2 is Ksp = [Pb][I]2 This gives the relationship between the ions in the saturated solution and is the maximum concentration possible without creating precipitation. In this lab‚ solutions of lead nitrate and potassium iodide will be mixed at a number of dilutions

Hypothesis I theorize that nothing will happen with Magnesium because it is such a soft metal. Zinc should turn a greener color‚ because that’s what happens to a lot of statues and sculptures. I theorize that iron will tarnish badly because in air it can get tarnished so oxidation

Positive Behavior Support Positive Behavior Support (PBS) is not a modification plan for students with difficult behaviors; it is a system for modifying the environment; as well as the way that teachers respond to these difficult behaviors. "Such environmental interventions‚ in turn‚ serve to make problem behavior less effective‚ efficient‚ and relevant and desired behavior more functional" (http://www.ldonline.org ). Teachers first should utilize a functional behavioral assessment in order to
