    Salinity ExperimentAimTo determine a method of measuring a soil sample's salinity level in order to measure 3 samples's salinity level. Hypothesis I think that by running a current through a salt solution and measuring the resultant amperage, a pattern in the recordings will help find a soil sample's salinity level. Variables Controlled - Amount of solution (100 mL), supplied voltage (4 V), amount of soil (50 gm) & water (150 mL) in soil sample's solution. Independent - Amps recorded by ammeter....

    Complex Ion Composition By Job's Method By Kelly Miller Smith, Inorganic Chemistry Dr. Virgil Payne 1: 00 lab Objective The objective of this experiment is to study the continuous variations method that is used to determine the composition of the solution Ni 2+ ethylenediamine complexes. Background To examine the interaction between two molecules in solution without isolating the compound Job's method is used. Although unstable compounds tend to be generated, this is not a reflection of weak int...

    Darryl Fagan Pd. 4 01-20-00 AP Chemistry An Activity Series Chemistry Lab 5 Introduction; In this experiment you will study some metals and some nonmetals to find their relative reactivity. A ranking according to reactivity is called an activity series. For example, an activity series containing the elements calcium, gold and iron would put the reactive calcium at the top, iron in the middle, and the un reactive gold at the bottom. If a piece of iron metal is placed in a solution of gold nitrate...

    Introduction For this experiment, we are going to determine the effect of temperature on solubility, to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically, the goal of this experiment is to prepare a saturated solution of Na 2 C 2 O 4 in water at different temperatures, determine the effect of temperature in solubility, and to apply Le Chatelier's Principle. We can do all this by simply titrating a certain amount of standard KMnO 4, and...

    Qualitative Analysis of Cations Introduction: The purpose of this experiment is to demonstrate the separation and identification of metal ions based on the insolubility of certain salts. The solubility rules should be taken into account. If a solution dissolves in water, the result contains both cations and anions. Analyzing different ions to discover their nature is the main goal of this experiment. Separation of the cations by testing the differences in solubility of different metal salts is d...
  • 1 0 M Copper Nitrate Solution

    ELECTROCHEMICAL CELLS 3-21-05 Purpose: In this experiment, several different half-cells will be prepared and connected to find the voltages generated. Also, the concentration will be change in one of the solutions to see how this affects the cell potential. Thirdly, the electrical potential of a cell containing silver and silver chloride will be measured. Lastly, a cell containing copper (II) and ammonia will be constructed. The potential and the Nernst equation will be used to calculate the for...

    Introduction The goal of this lab was to analyze the iron content in both iron tablets and cereal. The methods used to achieve this goal included using spectrometry to set a calibration curve and measure iron content within the mixture of cereal and the iron tablet. The absorbance of the mixtures were used in conjunction with the calibration curve to measure the amount of iron content in each. Experimental First the calibration curve was made by preparing a mixture of Fe (NO 3) 3 and KCSN with H...

    Acid-Base Equilibria: Determination of Acid Ionization Constants Introduction: The purpose of this lab is to learn about acid ionization constants and buffer solutions. We will be determining the acid ionization constant by finding pH with pH meters. In part three we will prepare a buffer solution and then observe the change in pH as either an acid or base is added. Data: Discussion: The majority of this experiment was focused on determination of Ka, or the acid ionization constant. To find Ka w...
