Pchem Formal Report

Synopsis: The main aim of the experiment is to find out the amount of calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange,… View Article

Rates Of reaction

During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment, we will have to conduct another experiment, to see what concentration of acid we will have to use. We done this using 0.1M, 0.5M and… View Article

Thermochemistry: Solid Sodium Hydroxide

Hydrochloric acid and sodium hydroxide are corrosive. Avoid direct contact. If any touches your skin, wash it off immediately. Solid sodium hydroxide is especially dangerous because it absorbs moisture rapidly from the air, forming an extremely corrosive liquid. Avoid spilling this solid, and if a spill occurs, clean it up immediately. Be sure to close… View Article

The burette was cleaned with de-ionized water

To determine relative molecular mass of a soluble base, X2CO3 by carrying out an acid-base titration with the following reaction , knowing the amount of hydrochloric acid used and the amount of substance Z used. Hypothesis: The X in substance Z is a group 1 element because substance Z is a soluble metal carbonate and… View Article

Atomic mass unit

Substance Z is sodium carbonate because the relative atomic mass of X calculated is 22. 99. The actual relative atomic mass of sodium is 22. 99. Hence, we can conclude X is sodium. 6) If de-ionized water was added into the volumetric flask beyond the calibration mark, the exact concentration of the solution of standard… View Article

Three defining moments in Canadian history

– All throughout Canada in the 20th Century there have been numerous events, actions, and decisions that we call defining moments. Canada has been through many battles, hard-chosen decisions, and changes that have changed the way Canadians live today. The second battle of Ypres, the life on the home front in World War Two, and… View Article

Turnaround at the Preston plant

The Preston plant of Rendall Graphics was located in Preston, Vancouver. The plant was bought from the Georgetown Corporation by Rendall in March 2000. The plant produced Precision coated papers for ink-jet printers which accounted for the majority of the plant’s output. The plant started to experience problems in the quality of their output of… View Article

Neutralization Titrations: The Determination of Soda Ash

I.Purpose: The goal of this experiment is to determine the weight % of Na2CO3 through the preparation of NaOH and HCl standards. The molarity of the standards will be found through titration of KHP for NaOH, HCl vs the known NaOH, and the unknown Soda Ash sample vs the known HCl. II.Equations and Sample Calculations:… View Article

Analysis of Commercial Bleach

Introduction: Many commercial products are effective because they contain oxidizing agents. Some products that contain oxidizing agents are bleaches, hair coloring agents, scouring powders, and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite, NaClO (sometimes written NaOCl). Commercial bleaches are created by bubbling chlorine gas into a sodium hydroxide solution… View Article

Star Apple (Chrysophyllum cainito) as an Antiseptic Mouthwash

a. Background of the Study As an effective mouthwash is one that does not only make the breath fresh but also serves as an antiseptic. It should not simply mask the effective mouth odor caused by excessive activity of anaerobic bacteria inhabiting the mouth. There is a need to prevent the increase in the population…. View Article

Chemistry project 12th

This reaction is highly exothermic, but that is not why the plastic produced is referred to as “thermoset”. Bakelite is a space-network polymer. Unlike linear and branched polymers, which are composed of long molecules that make them more or less crystalline, space-network polymers are highly and irregularly cross-linked throughout the structure. The sheer extent of… View Article

Agar Cubes Lab Report

Diffusion in agar cubes Introduction: All cells are dependent on a processes called diffusion, which is the movement of a substance from an area of higher concentration to an area of lower concentration. Cells need to obtain certain essential substances, like oxygen, for their survival. The rate of diffusion is said to be dependent upon… View Article
