Purpose: The purpose of this was to determine the concentration of sodium carbonate in an unknown sample by titration. The solution of hydrochloric acid was prepared and standardized using Na2CO3. Observations: Week 1: Standardizing hydrochloric acid using sodium carbonate with bromocresol green indicator Table 1: Titration of sodium carbonate using hydrochloric acid Trial | Mass of Na2CO3 (g) | Burette Reading (mL) | Final Volume of HCl (mL) | | | Initial | Final | | 1

For the seventh experiment we will be performing different type of test to see how different chemical react with each other. The first experiment will be a demonstration the professor will give to the class. the first experiment you will be performing will include a test tube you will add a couple drops of dilute hydrochloric. you will add this to five little pieces of zinc metal. In next experiment you will performed you will put 2 ml of 3% hydrogen peroxide solution in a test tube .you will also

1. The Tums tablet is insoluble in water. The water turns foggy when the Tums tablet is added. The particles of the tablet are suspended in the water‚ therefore the water appeared foggy and opaque. The Alka-Seltzer is soluble in water. The ingredients of Alka-Seltzer and the water react together to produce gas‚ thus bubbles formed in the solution. Whereas‚ the Rolaids tablet did not dissolve in water. The powder remained afloat on the surface of the water. Unlike the Tums tablet‚ Rolaids does not

PurposeIn this experiment‚ sodium hypochlorite (NaOCl) in acetic acid mixture was used to oxidize emdo-borneol (an alcohol) to camphor (a ketone). The product would then be purified by sublimation and then be analyzed by Infrared spectroscopy and melting point test. Procedure and ObservationsPlease refer to the lab manual and the carbon copy attached. Data and CalculationsWeight of endo-borneol = 0.2013gNo of moles of endo-borneol = 0.2013g/154.25g mol-1 = 1. 305mmolSince one mole of endo-borneol

INTRODUCTION Using the correct type of medical product to treat an injury is crucial for the injury to heal. A common product used in treatment of injury is a cold pack. After injury‚ it is common practice to ice the affected area to reduce swelling and therefore soothe the area. There are many types of cold packs that can be used‚ the most common being ice in a bag of sorts. Another popular kind of ice pack is disposable that consists of a small‚ thin compartment that contains a salt (NH4NO3)
