During the winter in some places it can get very cold, and it might even snow. People put many different things on the ground to make the snow melt, but which one really melts the snow the fastest? Does ice melt fastest with salt, sugar, or sand. There are many things that can solve this question. In order to see if something is soluble it needs to be mixed with a solvent (water). To be soluble means that it is able to be dissolved. There are three different possibilities that can happen.…

I. Science fair Question What material will make ice melt fastest? II. Background Research Did you ever wonder what makes ice melt fastest? This research paper is going to talk about how ice melt works. Terms that will be discussed in this paper will include freezing point, Phrases of matter, freezing point depression, and solution. Freezing point is the point when water turns into ice (What Makes Ice Melt Fastest). If you have ever lived in a cold climate, you have most likely have seen…

Procedure: Part A: Extraction stage 1. Place a 125 mL separatory funnel in a ring stand equipped with a small ring. 2. Heat the hot plate. 3. Heat the water (20 mL of hot water is needed) to a boil by placing it on top of the hot plate. 2. To the 125 mL Erlenmeyer flask, added two Tylenol (500 mg/ tablet) 3. Dissolved the solid by gently swirling the Erlenmeyer flask. 4. Let the solution cool for a few minutes (approximately till room temperature). 5. Add the mixture to the separatory funnel.…

Background: Isopods, or what are often called pill bugs, are crustaceans. Isopods live in damp environments. They can be found under rocks, logs and in soil. In this lab, 10 isopods were given a choice between salt water or regular water chambers to test their preference. The results were recorded every 30 seconds over a period of 10 minutes. Problem: It is known that isopods have a preference for moisture.This lab will specifically test whether or not an additive will affect a pill bug's…

ANTACID ANALYSIS: DETERMINATION OF STOMACH ACID NEUTRALIZATION USING ANTACIDS Authors: Alexxis Harris Constance Doty Brandon Hokenson Gavin Hunt Melissa Munoz Affiliation: Department of Chemistry, University of Central Florida Abstract The purpose of this experiment is to identify which antacid is the best at neutralizing stomach acid. Antacids are commonly used self-prescribed medications. The stomach produces hydrochloric…

was attracted to the Magnet. When it comes to the separation of Sand and Sodium chloride, they were separated because of the unique property of Sodium Chloride which is solubility. When the mixture of Sand and Sodium chloride was mixed in the water, the sodium chloride had the capacity of being dissolved in the water leaving the sand undissolved. When the mixture was filtered using a filer paper, the Sodium chloride went through the filter paper because it was soluble in water but the sand did…

1. Existing knowledge, research and views: The separation of the sulfur and iron powder was accomplished through magnetism. When combining the sulfur and iron powder to form a mixture, a magnet can be used to attract the iron separating it from the sulfur. Unlike the iron and powder, the salt and sand were separated through filtration. This is a method which separates solids from liquids. In the experiment, the mixture of salt, sand and water are separated as it is poured through a funnel with…

Introduction This accuracy lab of titration report experiment will discuss how to find the unknown substance molarity. By using some of the lab equipment to help guide and identify the molarity of the unknown substance. I believe that it will take around three hundred drops of sodium hydroxide (NaOH) for it to be able to reach to its endpoint of the unknown substance. My reason behind my hypothesis is… Methods In this lab experiment we use a buret to…

When hydrochloric acid was added to the unknown and known solutions, both resulted in no reaction. This also occurred when potassium hydroxide was added to both of the solutions. Barium chloride was then added to the two solutions, which resulted in a cloudy white precipitate from both of the solutions. A cloudy white precipitate also formed when calcium nitrate and ammonium nitrate were added to both the unknown and known solutions. These…

1. Fill a mason jar half-full with tepid water. Put it on the hotplate and raise the temperature to 98 degrees. Make sure you can keep it at this temperature for several hours. 2. Wash your hands. Cover the surfaces adjacent to your kitchen stove with paper towels. Place the test tube racks close to the stove on the paper towels. 3. Fill the pot with water and bring to a boil. Uncap your test tubes. Using your kitchen tongs, carefully drop your graduated cylinder, test tubes and their caps in…
