GRAVIMETRIC ANALYSIS OF A CHLORIDE SALT Report Submitted by: Ronald Milner Laboratory partner: Kiesha Mantik Lab Performed: February 16th‚ 2012 Group: Thursday Afternoon‚ Group F Date submitted: March 14th‚ 2012 Purpose: To determine the chloride content of an unknown soluble salt while illustrating the techniques involved in gravimetric analysis. Theory: In order to find the chloride content of an unknown soluble salt‚ that chloride can first be extracted from the

the extent to which the temperature and presence of common ions affect the amount of copper sulphate salt that can dissolve in 100 grams of water until it reaches saturation. In order to achieve the aims of this experiment‚ a methodical approach is taken to measure solubility of the salt at three different temperatures and then construct a solubility curve for copper sulphate. Additionally‚ copper sulphate is reacted with sodium hydroxide to investigate further the effect of common ions on

CASE ONE Two advertising media are being considered for promotion of a product. Radio ads cost $400 each‚ while newspaper ads cost $600 each. The total budget is $7‚200 per week. The total number of ads should be at least 15‚ with at least 2 of each type‚ and there should be no more than 19 ads in total. The company does not want the number of newspaper ads to exceed the number of radio ads by more than 25 percent. Each newspaper ad reaches 6‚000 people‚ 50 percent of whom will respond; while each

In this experiment‚ gravimetric analysis will be used to determine the unknown metal carbonate. Gravimetric analysis. Gravimetric analysis is a method where an ion being analyzed can be classified through their mass (Yoder 2018). Due to the fact that carbonates can be hygroscopic‚ which means it would be able to absorb water from water vapor‚ extra precautions have to be taken place to be able to get an accurate mass (Helmenstine 2017). This can be done by using a drying oven and a desiccator. A

Chapter 1 Introduction to Quantitative Analysis Teaching Suggestions Teaching Suggestion 1.1: Importance of Qualitative Factors. Section 1.2 gives students an overview of quantitative analysis. In this section‚ a number of qualitative factors‚ including federal legislation and new technology‚ are discussed. Students can be asked to discuss other qualitative factors that could have an impact on quantitative analysis. Waiting lines and project planning can be used as examples.

Copper Sulphate Calibration Aim The objective of this experiment is to determine the unknown concentrations of solutions. Introduction With the use of absorption of light a spectrophotometer sends UV wavelengths through solutions to determine their concentrations. The light absorbed is measured as the atoms‚ molecules and ions absorb the wavelengths of light that the spectrophotometer gives off (Meah‚2013). The level of light transmitted defines the amount of light absorbed‚ for instance‚ the lower

Introduction: The purpose of this lab will be to investigate the concepts of accuracy and precision for quantitative measurements using density as an example. The density of a sample will be found experimentally and compared to a known value. The relationship of averages and different analysis techniques to percent error will also be explored. Density is a characteristic of a substance which can qualitatively be described as the amount of matter (mass) squeezed into a given space (volume). The
