Experiment 5- Standardization of NaOH and determination of Molarity of an unknown Acid Objectives 1. Preparation and standardization of a 0.1M NaOH solution 2. To learn the technique of titration 3. Determination of the concentration of an unknown diprotic acid. Introduction Titration can be traced to the origins of volumetric analysis‚ which began in the late eighteenth century. Study of analytical chemistry began in France and the first burette was made by Francois Antoine Henri

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

In the fume hood‚ approximately 2g of Ca(OH)2 was dumped from a vail into a 250ml beaker. To avoid any left-over Ca(OH)2 inside the vail‚ certain amount of distill water wad added to it‚ and the vail was shook several times after the lid was closed. Pouring the solution in the vail into the beaker‚ and add distill water until it reached the 100ml line. Then‚ the beaker was put on top of a magnetic stir with a magnetic stir bar placed in it. Turning on the magnetic stirrer and allowing the stir bar

In this lab‚ the pH of flat sprite and a fresh sprite are compared two ways: one way was to record the pH directly with a digital pH probe and the other was to calculate the concentration through titration. Because the reaction is a neutralization reaction‚ the concentration of can be calculated if the concentration of is known. At the end of the titration‚ the moles of will equal the moles of and the pH is expected to be greater than 7 because the found in sprite is weak and is a strong
