Standardization of hydrochloric acid by sodium carbonate Concentrated hydrochloric acid is roughly 11 M. Pour out into a measuring cylinder about 2 cm3 of concentrated hydrochloric acid. Transfer it to a 250 cm3 flask and make up to the mark with water. Shake well. Put some pure sodium hydrogen carbonate or anhydrous sodium carbonate into an evaporating dish and heat gently over a low flame for about fifteen minutes‚ stirring continuously. Take care not to heat the mass too strongly or fusion

Algae Could Solve World’s Fuel Crisis Von Philip Bethge Dan Robertson is working on algae that can produce biofuel. Genetically modified blue and green algae could be the answer to the world’s fuel problems. Bioengineers have already developed algae that produce ethanol‚ oil and even diesel -- and the only things the organisms need are sunlight‚ CO2 and seawater.

The solution we will be standardized by performing multiple calculations to ensure the upmost accuracy. The acid used for this titration will be KHP (C4H5KO4). Phenolphthalein we be added to the beaker of the dissolved acid before the titration will be added. The titration

more efficient sources of power. At the forefront of research for these power sources are hydrogen fuel cells. This power source takes in the most abundant element in the universe‚ Hydrogen‚ and yields immense power without combustion or pollution. The three aspects of this scientific breakthrough are the fuel cells‚ hydrogen production‚ and hydrogen storage. Fuel cells are the devices with which Hydrogen is made into electricity. These use a technology much similar to that of something we are

SCH 3U0 May 7th 2013 Percent Yield of Calcium Carbonate Introduction: The purpose of this experiment is to examine the percent yield of a precipitate in a double displacement reaction. A solution of calcium citrate and sodium carbonate were mixed together‚ then the products were filtered out as so only the precipitate remained. The filtered paper was then dried and the mass of the precipitate in the experiment divided by the theoretical mass of the precipitate from the calculated gave the

Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation
