Acid-Base Titrations A Titration of Potassium Hydroxide Phthalate and Sodium Hydroxide Hanna Piper Department of Chemistry‚ SUNY College at Brockport‚ Brockport‚ NY 14420 Chemistry 205.06 Abstract Titrations are used to find the molarity of an unknown solution. A titration begins with an analyte and titrant being used to measure the unknown molarity of the analyte. In the following experiment‚ sodium hydroxide was used as the titrant and potassium hydroxide phthalate was used as the

Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus

GOTTHARD BASE TUNNEL‚ SWITZERLAND 1. INTRODUCTION Currently under construction to stretch a record length of 57 km‚ the Gotthard Base tunnel located in Switzerland spans the north of Europe‚ spanning through the Swiss Alps to the south of Europe. This railway tunnel has been designed to bypass the inefficient route of windy roads and cutting down travel time. The Gotthard Base tunnel consisting of twin tunnels is connected by cross passages at every 325m. The twin tunnels have been constructed

STANDARDIATION OF ACID AND BASE Eunice Ivy B. Gamboa ABSTRACT Solutions of known concentration are prepared by dissolving measured masses of standard acids in distilled water. The concentrations of unknown solutions of sodium hydroxide are determined by titration. An acid solution reacts with a base solution in a "neutralization" reaction. Titrations permit the concentrations of unknown acids/bases to be determined with a high degree of accuracy. In order to analyze unknown acids/bases‚ we must have a "standard"

Five Bases of Power Maria Mayorga BCom230 November 28‚ 2011 Jay Johnson Five Bases of Power Power is said to be ability of one person‚ group‚ or organization to control another person‚ group‚ or organization. Power is also refer to when one individual makes another do what the other wished through fear‚ force‚ persuasion‚ or reward. For example someone may be powerful because he or she could fire or assign a task someone does not like. Other could be powerful by having the ability to

POLLUTION Pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy‚ such as noise‚ heat or light. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Forms of pollution The major forms of pollution are listed below along with the particular contaminant

Four bases of segmentation Geographic Collecting and analysing information according to the location of the customer or other data source. Geographic segmentation is often used in marketing‚ since companies selling products and services would like to know where their products are being sold in order to increase advertising and sales efforts there. A local shop such as a local takeaway use geographic segmentation by targeting customers within a 10 mile radius‚ they can do this by posting leaflets
