    Purpose: During our lab‚ Galileo’s Water Clock‚ we created our lab to describe the motion of a ball on a plane using the water clock as an alternative method for measuring time. Our main purpose in this lab was to determine if the displacement of the ball is determined by the time or the time squared. Procedure: Once the water clock was set up‚ a ball was let go from the ramp at various distances for three trials each. Once the ball was let go‚ the water clamp was opened and then immediately

    Redox Titration Lab ABSTRACT: In this lab‚ 0.010 M purple-colored potassium permanganate solution was standardized by redox titration with iron (II) ammonium sulfate hexahydrate (FAS). The average mass of the three flasks of FAS was 0.483 grams. Once the concentration of the standard solution of KMnO4 (aq) was determined‚ it was used to determine the concentration of Fe2+ in iron pills. On average‚ there was 0.01813 L of solution used. With this information and the balanced net-ionic equation

    ...............................(1) Measurement of Relative Water Content (RWC%);Relative Turgidity (RT %): Relative water content was estimated according to a modification of the method of Weatherly (1950); Weatherly and Barr (1962); Slatyer (1957);Fletcher et al. (1988)on the final day of the experiment and was calculated by the formula given byKramer (1983).Detached leaf samples were weight immediately and floated on distilled water in a darkened refrigerator (5˚C). Saturation of the leaves was

    Vitamin C Introduction: The lab consists in determining the vitamin C concentration in a solution by a redox titration using iodine. Vitamin C (ascorbic acid) is a water-soluble‚ essential oxidant that plays a vital role in the protection of the body from infections and disease it is acquired from primary fruits and vegetables. With the use of different materials as natural orange juice‚ Tampico (chemical orange juice) and other solutions that contain vitamin C we will find the amount of vitamin

    Silver Nitrate Titration Introduction This experiment was conducted to work out the concentration of the chloride ions in the school swimming pool water and to see if it fits in the required range of concentration of chloride ions in the swimming pool water. This was done by titrating a small sample of the school swimming pool water with silver nitrate‚ which would form a white precipitate of silver chloride. The equation of this process is: The end point of the titration (when all of
