Name : Joseph “Fitz” Maro Lab Partners : Bryan Keelon and Laura Taylor Title: Reactions of Acids with Common Substances Date: October 30, 2007 I hereby declare upon my word of honor that I have neither given nor received unauthorized help on this work. Abstract : - In this lab we were introduced to the titration method of chemical analysis. It’s used to determine the acid content in a familiar substance, vinegar. In a titration we use the known concentration of one reactant to determine the concentration of the other. An indicator is used to determine when the concentrations are equal. -Our results Keywords: Acids: solutions in water that have excess H+ ions. Bases: solutions that contain excess OH- ions. Titration method of analysis: a titration where a known quantity of acid solution is measured out; then a solution of base (usually NaOH) is added slowly until just enough has been added to react with all of the acid. Molarity: defined as the number of moles of a substance in exactly 1 liter of solution. -Questions: In general it can be concluded that the effect of the acids is quite
