Lacy Taylor iLab‚ Week #5 UNKNOWN ACID AND BASE TITRATION Introduction The pH‚ or the concentration of the hydrogen plus ion [H+]‚ is one of the most critical parameters in predicting if a system will corrode‚ or determining why a system is corroding. PH is defined as the negative log base 10 of the hydrogen plus ion concentration in the units of moles per litre. Procedure pH MEASUREMENT OF UNKNOWN SOLUTIONS Obtain the following apparatus from the equipment menu: 100 mL beaker

Determining the enthalpy of neutralization by calorimetry Anam Iqbal Partner’s name: Danielle Hodgson TA’s name: Karinna Section # 003 Due date: November 24‚ 2009 Introduction The purpose of the experiment is to determine the enthalpy of neutralization reactions by calorimetry. Calorimetry‚ is the science of measuring the amount of heat. All calorimetric techniques are therefore based on the measurement of heat that may be generated (exothermic process) or consumed (endothermic process). The

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

If you get a substance liquid or solid take it and try test try to figure it out what it is. When you bring it in have your other 5 buddies help test to see what it is. They should all try different chemicals from the other people. They see should all look at the chemical and physical appearance. My claim is the the mystery mixture was Citric acid‚ road salt‚ and baking soda. The reason I thought it was this mixture because of the physical and chemical appearance. I agree with baking soda road
