Abstract: The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield.
Purpose: The purpose of this lab is to titrate an unknown solid acid (KH2PO4) with a standardized sodium hydroxide solution. After recording and plotting the data, the acid’s equivalence point will be recorded once the color changes. Using the equivalence point, the halfway point will be calculated, which is used to determine the acid’s equilibrium constant. The acid’s calculated equilibrium constant will be compared with the acid’s established pKa value.
Materials assignment notes. We have come together as three separate companies who have experience of working with each other on many other projects, to provide the specified requirements that the client is looking for. After surveying the site and looking at the surrounding areas we have come up with a design that incorporates all three of our products.
To separate the Ramos mixture the group first first conducted the dissolve, filter, evaporate method, and prepared the lab for as well. Though for this lab the substance
Introduction It is essential for chemists to know how to separate mixtures when needed. This will come in handy when an element is toxic and cannot be mixed with other elements or compounds(Wood, 2023). It even came in handy back when gold miners needed to separate soil and water to find the gold(Libretexts, 2022). Different separation techniques allowed people to understand mass spectrometry, biomedical substances, and proteins. Techniques
Procedures In this experiment, an unknown mixture was given, that contained both sodium bicarbonate(NaHCO3) and sodium chloride(NaCl). The purpose of this experiment was to find the percent (%) composition of the sodium bicarbonate and sodium chloride in the unknown mixture. Hydrochloric acid(HCl) and a scale were materials that were also used during the lab.
Double Replacement Lab Report Date Completed: October 8, 2015 Objective To analyze and determine if a chemical reaction occurred between two compounds using the concepts we learned in class. Also, if the chemical reaction occurred, to determine if it formed a precipitate or gas. Safety General Safety Precautions: Do not touch the chemicals Use of gloves and coats are recommended, use of goggles should be required Keep the work area clean Dispose of the chemicals properly, DO NOT dispose them in the sink Clean up your work station Wash your hand before and after the lab Make sure all chemicals are labeled correctly NEVER return chemicals to reagent bottles Use the wafting technique to smell the chemical Clean up spills immediately
Use the evidence provided by the tests to identify the mystery powder. The mystery powder (#5) is the baking powder. My partners and I figured this out because the physical and chemical properties of both of the substances are very similar. For example, both powders are not soluble in water, and they both turned red when they reacted with the universal indicator.
You can create an inventory policy for the office by scheduling inventory to be taken monthly, or weekly, whichever schedule fits your offices ordering needs. You could distribute the task among employees by doing it in pairs or assign a list of supplies that each person is responsible for keeping inventory of. A very vital tool for completing an inventory check is having a list of the supplies and equipment that you need to take inventory of. You can use Excel to create the inventory list. I would recommend that this list have at least two columns.
Title: Introduction: A-mountain lies in Southern Arizona, a region known as a desert. There are factors that contribute to the growth of certain plant life in certain areas. The north and south side of the mountain is expected to have contrasting difference due to the amount of sunlight each side receives. Exposure to sunlight affects the plants growth and overall life.
Experimental Procedure Identifying the Unknown We performed three tests on our compound to definitively identify it. First we combined 5 g of our unknown compound with 10 mL of distilled water and measured the pH change in the water to test its solubility. Then, to try to identify the cation present in our compound and narrow down the possibilities, we held a sample over a flame and watched for color change. We performed an acid test where we applied a few drops of HCl and watched for a bubbling reaction, to test for the presence of carbonate.
Purpose and Techniques: This experiment has the aim to determine a chemical formula of hydrated compound, which ingrains cupper, chloride and water molecules in its structure. In order to find this hydrated compound, it is necessary to use the law of multiple proportions. In other word, finding the appropriate variables values to this compound (CxCly*zH2O). Additionally, two major steps are required to proceed the experiment.
How do the goals of a liberal arts education lend themselves to achieving academic integrity? Liberal arts education provides opportunities for students to become widely informed and skilled citizens. It allows students to have awareness in different areas of studies and develop broader cognitive abilities. Moreover, liberal arts education states several values which are to be developed in students throughout their studies. Academic integrity is the set of values for behavior which encourage to avoid plagiarism, cheating, and dishonesty in academic life.
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
How Transmission Fluid Warns Of Potential Problems With Your Car's Transmission Monitoring the transmission fluid in your car is one way to track the condition of the transmission. You should get in the habit of checking the fluid periodically just to make sure everything is working okay. You'll want to check the fluid level along with the color and consistency of the fluid. Here's what you need to know.
