PPT-Chapter 4: Aqueous Reactions and Solution Stoichiometry

Jennie L Borders Section 41 General Properties of Aqueous Solutions A solution is a homogeneous mixture of two or more substances A solution in which water is the dissolving medium is called an aqueous solution. 1. 2. Liquid Dosage Forms. Solution: . solutions are clear Liquid preparations containing one or more active ingredients dissolved in a suitable vehicle.. . Suspension:. (Solid in Liquid dispersion) Liquid preparations containing one or more active ingredients suspended in a suitable vehicle.. 1 Aqueous SolutionsWater is the dissolving Some Properties of WaterWater is .

A physical change occurs when a substance undergoes a change in properties, but not a change in composition. Changes in the phase of a substance (solid, liquid, gas)or formation/separation of mixtures of substances are common physical changes.
