Urinary Analysis Bio 224L Wed. 9:30-10:50 Amie Gohn 11-30-11 Mr. Brown Introduction There are many different factors that can affect urine including volume‚ urine concentration‚ and pH levels. Factors that affect urine volume are fluid intake and reabsorption‚ which affects the amount of urine released. Urine concentration is measured by the concentration of dissolved solids present in a person’s urine‚ which is affected by water intake levels as

electrolyte will be a poorer conductor than a solution containing an equal concentration of a strong electrolyte Brønsted-Lowry theory Acid is a proton donor Base is a proton acceptor H2O + HNO2 H3O+ + NO2- The conjugate base of the acid HNO2 is nitrite ion. The conjugate acid of water is the hydrated proton written as H3O+ Amphiprotic solvent – solvent that can act either as an acid or as a base‚ a classic example is water. The weakest acid forms the strongest conjugate base The tendency of a solvent

spray things that can be easily inhaled. However‚ inhalants are broken down into 4 subcategories: volatile solvents‚ liquids that vaporize at room temperature such as gasoline‚ aerosols‚ sprays such as hair spray‚ gases‚ such as nitrous oxide‚ and nitrites‚ such as leather cleaner. The article also explains some effects of using inhalants like much of our readings do. Effects such as dizziness‚ drowsiness‚ and slurred speech are all

Quan Chapter 15: Redox Titrations 1. (A) Which of the following is true of a redox titration? (i) Since the redox reaction is spontaneous‚ the equilibrium constant does not have to be large for an effective titration. (ii) The titration effectiveness is increased when the two half-reaction potentials are far apart. (iii) Without an indicator the equivalence point cannot be detected. (iv) For an effective redox titration‚ the reducing agent must always be in the buret. (v) The equivalence
