Unknown Compound
The quantitative solubility of the unknown compound was determined to be 29/100ml. The known solubility of sodium sulfate is 28.11g/100mL water. Using the found solubility to compare to the known solubility of sodium sulfate. This solution created in the solubility test, the conductivity of the unknown compound was tested using an Ohmmeter to measure the resistance of the solution. Resistance is the measure of a substances ability to conduct
Unknown Substance D Lab
The observations that were made during the conductivity testing process were that, according to the chart given in the lab, the covalent compounds in solution had a low scale of conductivity, while the ionic compounds in solution had a high scale of conductivity. The sugar had a scale of 0 with no red light seen in the red LED and no light present in the green LED, and the levulose had a scale of 1 with a dim red light seen in the red LED and no light present in the green LED. The baking soda had a scale of 3 with a bright red light seen in the red LED, and dim light present in the green LED and the table salt had a scale of 4 with a very bright red light seen in the red LED and medium light present in the green LED. These observations prove that substances that are made of covalent bonds have a low conductivity in a solution, while the substances that involve ionic bonds have a high conductivity in solution. When Unknown Substance D was stirred in a beaker with the distilled water and tested for its conductivity, Unknown D’s conductivity in solution had a scale of 1 with a dim red light seen in the red LED and no light present in the green LED, just like levulose which is also a covalent compound.
Qualitative Analysis Lab: Unknown Substance A
This result showed that the unknown substance had a high melting point, making it identified as sodium chloride. Insoluble substance C was identified by adding two drops of iodine tincture. Substance C turned into a deep blue color in the solution and was then determined to be cornstarch since the blue color indicates if a substance in the solution was cornstarch. Substance D in this experiment was not given but through the report and different testing, substance D would be sodium hydroxide. Substance E would now be the next experiment in the lab..
Unknown Ionic: A Qualitative Analysis
Scientist preform many qualitative analyses to determine the identity of an unknown ionic compound. The determination of the compound involves preforming a series of test and using a high level of logical thinking. In the project unknown cations and anions were tested to determine each identity. Once the identity was determined logic trees for each, the cation and anion, were constructed to help identify the unknown compound.
Concentration Of Sodium Dodecyl Re
In this experiment, a series of SDS solutions at various concentrations are tested for their conductance at two different temperatures, 25 °C and 50 °C. For detailed procedure, refer to the lab manual (J. F. Wójcik and T. S. Ahmadi, Experimental Physical Chemistry, 2015; p.125-129.). Data Sodium dodecyl sulfate has a molecular weight of 288.372 g/mol, with a density of 1.01 g/cm³. The melting point of SDS is in the ranges of 204 -205.5 °C. In this experiment, 8.6151 g of SDS was weighed to make a 500-mL 0.06 M solution.
Lab Report Essay
The purpose of this lab is to test various element for their conductivity, solubility, and physical characteristics. We will see if the object is a metal, nonmetal or a metalloids (semimetals). Metals are commonly known as to be ductile (can be used in wiring), malleable (can’t be break down when pressed down hard), have a metallic luster, and are conductors of heat and electricity. Non-metals are more likely to be non lustrous, brittle and poor conductors of heat and electricity. Where as metalloids has the same characteristics of both metals and nonmetals.
Ionic Bonding Research Paper
As a result of their strong bonds these molecules have a high boiling and melting point, a high polarity and are typically solid at room temperature. Ionic bonds involve a metal and nonmetal because metals
Ionic And Covalent Compounds Lab Report
Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
Properties Of Substances Lab Report
Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has

Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, definitions of each relating factor were researched, leading to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound is formed when two or more nonmetal atoms share valence electrons; covalent compounds are also categorized into two sections: polar covalent and nonpolar covalent. Furthermore, polar covalent compounds dissolve in water, while nonpolar covalent compounds do not.
