Common Engineering Materials

What are common engineering materials and why are they important? Throughout history, the significant accomplishments of each era have consistently revolved around the development of new materials, playing a pivotal role in the advancement, prosperity, safety, and overall well-being of humanity. Since the dawn of civilization, it has consistently been the introduction of innovative materials…

Surface Tension of Liquids

Background and Theory This laboratory experiment investigates the surface tension of different working fluids and how contamination can drastically affect surface tension. Surface tension is a result of the molecules deep within the fluid repelling each other while the molecules at the surface attract each other [1]. Introducing contaminates like detergents into the surface of…

Specific Gravity, Density and Viscosity of Liquids

Background and Theory The object is to determine how the density, kinematic viscosity and dynamic viscosity of a sucrose solution, as the concentration of the solution are varied. Density is defined as ratio between the mass over the volume. [1] The expected outcome of this experiment is that there will be a correlation between concentration…

Synthesis of a Copper Coordination Compound & Solubility

Synthesis of a Copper Coordination Compound & Solubility

The purpose of this experiment is to prepare a coordination compound of a transition metal, calculate the % yield and then determine the solubility of this compound and solve for Ksp. After conducting this experiment the calculated % yield was 38.2%. The claim is that the experimental Ksp for this compound was 0.0112. For experiment…

Polarity

Polarity

For the first part of the experiment, predictions where made on how different solutes would dissolve in different solvents. The two solvents used were water which is a polar and hexane which is a non polar. Knowing that polar molecules dissolve polar molecules or molecules with a charge, but they do not interact with none…

Kinetics

Kinetics

The Purpose of this experiment was to determine the order of the reaction and how changing the molarity changed the k’ value. To being this experiment 0.2M NaOH concentration was made. Phenolphthalein was then added to the NaOH and the absorbance vs time was recorded. Once all the concentrations were recorded they were plotted to…

Buffer

Buffer

Buffers are important for many different reasons. One of the most critical roles of a buffer is when it comes to biology most biochemical processes can only occur when the pH inside the body or cell remains within a fairly narrow range, “An excess of H+ or OH- can interfere with the structure and activity…

What is metal vs metal alloy?

Why are metals important? Metals are used virtually everywhere from paperclips to huge tractors or aircraft. A tractor uses various metals for various components, for example, copper is used to help cool off the engine because of its thermal properties. The engine block is made from cast iron because of its high strength. Finally, the…
