Determination of Equilibrium Constants Introduction Bromothymol blue is an indicator for many acid-base titrations. When adding different solutions within the indicator it is to react and change colors‚ in this experiment the different colors were blue‚ green‚ and yellow. In the following experiment‚ obtaining the absorbance levels for each one makes it possible to calculate the equilibrium constant. Materials and Methods For this specific experiment there are a few materials that are crucial

Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula

People like to eat organic food‚ they think organic food is good for their health. And they think organic food is better for environment and kind of animals. So‚ nowadays people are trying to buy an organic food‚ it make organic food increasing price. On the other hand‚ many experts say that the organic foods are better than other. 1. What Qualifies as Organic? For the last time the organic product very important for people who like to eat organic food but now all organic foods are grown and

Before I go on about the use of fertilizers in organic farming‚ you must first understand what organic farming is. The simplest way to describe organic agriculture is agricultural production without the use of synthetic chemicals (fertilizers‚ pesticides‚ antibiotics‚ etc). For crop production‚ organic materials such as compost and manure are used to maintain soil organic matter and as sources of nutrients. Nitrogen-fixing as well as pest resistant plant varieties are utilized. The incorporation

Report: Calculating the Spring Constant and Verifying that Energy is Conserved Within a System Abstract: An experiment was conducted to determine the spring constant of a spring in the cart by measuring the force required to compress a spring as well as the distance the spring compressed relative to the equilibrium position. A cart was placed onto a slanted track and speed and force censors were used to record appropriate data. The spring constant was determined by substituting
