A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. The probe The pH probe measures pH as the activity of hydrogen ions surrounding a thin-walled glass bulb at its tip. The probe produces a small voltage (about 0

Acid-Base Titration Using a pH Meter Bradley Holloway and Jennifer Parker Period 6 April 16‚ 2013 Introduction: In chemistry‚ the ability to find molarities of acidic and basic solutions is a convenient way to convert between moles of solute and the volumes of their solutions. Through the process of titration‚ the molarity of these acids and bases can be found to a high level of precision. To begin titration‚ one solution is added to a second solution slowly until a certain point

A VERIFICATION AND VALIDATION Verification and validation is a systems engineering discipline that determines if work products comply with their specifications and are fit for their intended use. More specifically: Verification establishes the truth of correspondence between a work product and its specification (from the Latin veritas‚ “truth”). Validation establishes the fitness of a software product for its operational mission (from the Latin valere‚ “to be worth”). It answers
