IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

Gargar IV – St. Ezekiel 10/7/13 Introduction A lava lamp (or Astro lamp) is a decorative novelty item‚ invented by British accountant Edward Craven-Walker in 1963. The lamp contains blobs of colored wax inside a glass vessel filled with clear liquid; the wax rises and falls as its density changes due to heating from an incandescent light bulb underneath the vessel. The appearance of the wax is suggestive of pāhoehoe lava‚ hence the name. The lamps are designed in a variety of styles and colours

Melting Ice * Salt is routinely used to make icy roads and sidewalks safe in the winter. As soon as the salt comes in contact with the ice‚ the surface of the ice starts to melt. This only works‚ however‚ if the temperature outside is at or near freezing. If it is too cold outside‚ the ice itself becomes very dry and salt is not as effective in melting it. Salt Reduces Freezing Temperature of Water * Salt works by lowering the freezing temperature of water. Salt water needs to reach a colder

Freezing Point Depression Purpose: The purpose of this lab is to demonstrate freezing point depression by dissolving salt into two liquids and monitoring temperature. Materials: test tube‚ Thermometer‚ 10 mL graduated cylinder‚ 2 micropipettes‚ Styrofoam cups‚ 4 pieces plastic wrap‚ 70% ethyl rubbing alcohol‚ 91% isopropyl rubbing alcohol‚ ice‚ distilled water‚ rock salt Procedure: Using the graduated cylinder‚ measure 2 mL of alcohol and pour it into the test tube. Add 10 mL of

Chapter I. BACKGROUND OF THE STUDY Charcoal one of the earliest known forms of ink‚ was used as early as 30‚000 BC. The first of its use documented in the continent of Europe. It may be a bit primitive to these modern times but still very useable for those who want to try it. The recipe of making it however is similar to those inks made by ancient civilizations such as the ink used by the Ancient Egyptians. We propose to make charcoal ink as a statement to increase of those in the Philippines who

There are many chemicals in our world that are soluble‚ however‚ these chemicals have to follow a set of rules to determine how soluble each chemical is and if it is at all. This is what we call solubility laws. These laws show what chemicals are soluble and which ones are insoluble. They also describe what chemicals can be dissolved and what chemicals cannot dissolve. These chemicals are them recorded on Solubility tables which list solubility and how soluble the chemicals are. According to Busch

• Incensement of total capacity of treatment plant and improvement to water quality can be achieved vary easily. It’s possible due to lamella settlers‚ which provide high treatment in smaller footprint and high degree of settling capacity also process is more efficient and faster than conventional treatment with sedimentation tank. That because of one of most important feature of lamella settlers‚ are series of inclined plate which the suspended particles goes down with water flow‚ where solid particles

Density of Solutions Lab Purpose: The purpose of this lab was to find out the densities of the known and unknown Solutions that were given to us. This can be found by dividing the mass by the volume of the Solutions. The other purpose of this lab was to perfect our skills in finding out the percentage error‚ uncertainties‚ random error‚ and systematic error. Variables: Independent: Mass Percentage of Solution (KCl); Unknown Solution; Temperature Dependent: Density Materials: 10.00 mL
