Determining the percent Concentration of a given Solution using Titration Morphy Kuffour Mrs. Langlis‚ AP Chemistry C-D 9/24/2017 Purpose: Determining the precise concentration of vinegar through titration using a standard solution of Potassium Hydroxide (KOH) (aq) Background: Vinegar is a solution of acetic acid (CH3COOH) in water. The concentration of acetic acid in Vinegar is written as a Molarity (mol/L). In this experiment‚ titration is used to determine the concentration of acetic acid in

Ski jumping as an Olympic sport deserves more recognition. Ski jumping was created and thought of in Norway‚ the first ski jumper being ole rye‚ a Norwegian army lieutenant. He decided to try something out‚ so he set up a jump with the assistance of his peers (who were also in the army) and his first jump was 9.5 meters‚ leading to the birth of the sport in 1809. Ski jumping first caught my eye while visiting my friend in Switzerland. He was quite an avid Ski jumper and even competed in several national

amount of acid in our stomachs. This excessive acid production results in the unpleasant symptoms of heartburn and may contribute to the formation of ulcers by irritating the stomach lining. To relieve such symptoms we often use antacids. Antacids are bases (most commonly bicarbonates‚ carbonates and hydroxides) that are used to neutralize the excess stomach acid. Fluid magnesia was invented in 1817 by the Irish pharmacist Sir James Murray (1788–1871). Murray built a plant to produce a mixture of magnesium
