1.1 Overview: In a research lab, Mr. Z trying to formulate a colloidal dispersion system with sodium lauryl sulphate. What type of colloidal system is suitable for sodium laurly sulphate and also we have to discuss the different stability factors for sodium laurly sulphate dispersion. 1.2 Solution to the question: Introduction of colloids: Colloids are homogeneous non-crystalline substances. Here one substance is divide into more minute particles called colloidal particles and then it…

Preparing Dilutions of the Silver Nanoparticles 1. Gather all materials. 2. Put on a pair of disposable gloves. 3. Make a paper towel damp with some 70% isopropyl rubbing alcohol. Wipe down the work surface with the rubbing alcohol-dampened paper towel. 4. Using a permanent marker, label the five baby food jars #1 to #5. 5. Using the 25 milliliter (mL) graduated cylinder, measure and pour 22.5 mL of distilled water (from a new, unopened container) into each of jars #2, #3, #4, and #5. 6. Using…

What factor(s) affect the rate of reaction? Problem: What effects does temperature have on the rate of reaction? Purpose: The aim of this investigation is to investigate how changing the temperature of sodium thiosulphate affects the rate of reaction in a chemical reaction. In order to complete this practical the temperature will be changed three times and the rate of reaction will be measured each time. Variables: Independent: -the temperature of the sodium thiosulphate. Dependent:…

Introduction: DNP and research question The organic compound 2,4-dinitrophenol (DNP) is a crystalline solid with the molecular formula C6H4N2O5. The molecule is soluble in water to some extent and is fully soluble in sodium and potassium hydroxide solutions. The compound can also be explosive. It is usually used in dye, weed killers, wood preserver, photographic development among other things and it has even been used as a weight loss agent. In fact, it has been claimed to be the king of the…

1. Synopsis The main aim of the experiment is to find out the percentage of calcium carbonate in toothpaste by using back titration since calcium carbonate is an insoluble salt and does not dissolve in water. Back titration is a reverse method of titration used to obtain unknown concentration of analyte. A roughly weighed quantity of toothpaste? calcium carbonate is dissolved in a known amount of hydrochloric acid and is then titrated against sodium hydroxide. An orange colour will be observed…

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.…
