The Titration of a Basic Solution of Unknown Molarity with a Standard Hydrochloric Acid Solution Abstract The aim of the experiment was how to determine the molarity of a solution. My hypothesis was if I have to determine the molarity of a NaOH solution‚ then I would have to use a standard solution of HCl solution because I would need to neutralize each other to determine the concentration of the solution of NaOH. The method that I used for this experiment was titration. Titration helped

textbook in 1789 on chemistry in it he introduced the Law of Conservation. He founded the 3 types of matter (solid‚ liquid‚ and gas). Along with this he also established the metric system. Lavoisier also made a lot of enemies because he had disproved various old theories. In experiment 2.1 we wanted to know if the mass of salt will

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

Lab for Chemistry 221 Lab: How much sugar is in a Can of Coke? Abstract: A 50mL (we used 100mL) volumetric flask was used to determine the amount of sugar in a can of Coke per mL in 5 different solutions. Using the calibration curve we determine the amount of sugar per mL in a can of coke. This experiment concluded that there is 43.83g of sugar in a 12oz can of Coke. Introduction: This experiment was conducted to determine the amount of sugar in a can of Coke and to and use a calibration

Abstract The separation of a Fe3+ and Ni2+ mixture was firstly investigated; followed by the determination of the Fe3+ and Ni2+ content (concentration) in the original mixture. It was found that iron was a yellow solution and nickel respectively had a greenish colour. Their original concentrations respectively were 0.03669 M for iron and 0.03159 M for nickel. Introduction Ion exchange materials are insoluble substances containing loosely held ions which are to be exchanged with other ions in
