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

UFOs‚ Underground Bases‚ and Government cover-ups Julian Mercado October 1‚ 2010 UFO‚ Underground Bases‚ and Government cover-ups Introduction UFOs have been seen by people all over the world. People of different cultures and ethnicities have different names for these unknown craft. In Spanish it is “objeto volante no identificado”‚ and in German it is actually UFO. Regardless of what race you are‚ UFO means the same thing‚ “Unidentified flying Object”. Let me be clear on this. It means

POWER AND ITS POWERS: The Supremacy of Power Frank Chodorov‚ an American writer and libertarian once said “The State acquires power and because of its insatiable lust for power it is incapable of giving up any of it. The State never abdicates.” When I was in my high school‚ I always dreamed for Utopia‚ a perfect state wherein there is no poverty and starvation. Power is delegated in every people and there’s equality‚ justice and freedom. Utopia sometime refers for World peace‚ this may sounds

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

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"

Leadership in Nursing. Definitions‚ Theories‚ and Styles of Leadership Developing future nurse leaders is one of the greatest challenges faced by the nursing profession (Mahoney‚ 2001). Powerful leadership skills are needed by all nurses—those providing direct care to those in top management positions. Anyone who is looked to as an authority (e.g.‚ a nurse taking care of a patient) or who is responsible for giving assistance to others is considered a leader (Mahoney‚ 2001). A clinical nursing

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
