Acids Bases and pH Scale I. Acids *Acids are ionic compounds ( a compound with a positive or negative charge) that break apart in water to form a hydrogen ion (H+). *The strength of an acid is based on the concentration of H+ ions in the solution. The more H+ the stronger the acid. Example: HCl (Hydrochloric acid) in water Characteristics of Acids: **Acids taste sour **Acids react strongly with metals (Zn + HCl) **Strong Acids are dangerous and can burn your skin

First Law of Thermodynamics The first law of thermodynamics states that the energy cannot be created nor destroyed it can only be changed from one form to another. Another name for this law is the law of conservation of energy. This means that the total energy of a system plus its surroundings is constant and does not change. Energy can‚ however‚ be transferred in or out of the system and to or from the surroundings through work or heat. Conservation of Energy Energy may be defined as the

Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon
