The Effect of Sodium Carbonate on Hard Water Aim === In this experiment, we aim to investigate the effect of sodium carbonate on hard water. Method ====== Firstly, 25.00cm3 of a sample of water was pipetted into a clean conical flask. The pipette was used because this measures and delivers a very accurate amount of liquid (to the nearest hundredth of a cm3, or 0.01cm3), but care had to taken to make sure it was not held by the bulge, as this could have made the amount inaccurate

Satisfactory EssaysInvestigation of the Thermal Decomposition of Copper Carbonate Aim: Copper has two oxides, Cu2O, and CuO. Copper carbonate, CuCO3 decomposes on heating to form one of these oxides and an equation can be written for each possible reaction Equation 1: 2CuCO3 (s) Cu2O (s) + 2CO2 (g) + O2 (g) Equation 2: CuCO3 (s) CuO (s) + CO2 (g) The aim of this experiment is to prove which equation is correct. This can be done by volumetric analysis i.e. calculating the volume of gas produced. This is then

Better Essays5.1 What is Molten Carbonate Fuel Cell (MCFC) ? It a cell that takes Hydrogen, Oxygen and carbon dioxide as feed and produces water. It operates at extremely high temperature (between 6000C – 7000C). Molten Carbonate fuel cells are usually %45 to %55 efficient. That is due to heat lost from the chemical reaction (not all of the energy converts to electrical energy. This report will demonstrate the components of molten carbonate Fuel cell, what there mode are of and how they function. 5.2 Advantages

Satisfactory EssaysDetermining the Correct Equation for the Decomposition of Copper Carbonate Introduction and background information: Important points to note: ‘At room temperature, 25°C and atmospheric pressure at 1 atmosphere, I mole of any gas will occupy a volume of 24 dm³.’ We will need this to work out how much copper carbonate to decompose to obtain a sufficient amount of carbon dioxide gas. To work out the amount of copper carbonate to use I will need to use the following equations: Number

Better EssaysSoftening Hard Water With Sodium Carbonate Prediction ---------- In a preliminary experiment, we discovered that adding 1g. Na2CO3 to hard water softened it slightly. We tested both tap water and distilled water with the sodium stearate and discovered that tap water was far harder than distilled water, we then tested tap water that 1g of Na2CO3 had been applied to. This solution was softer than the original tap water. The exact results were; Type of water Soap solution required
