Acid-Base Titration Pre-Lab Discussion In the chemistry laboratory‚ it is sometimes necessary to experimentally determine the concentration of an acid solution or a base solution. A procedure for making this kind of determination is called an acid-base titration. In this procedure‚ a solution of known concentration‚ called the standard solution‚ is used to neutralize a precisely measured volume of the solution of unknown concentration to which one or two drops of an appropriate acid-base

Acid-base titration Aim To study the titration curve of a strong base-strong acid‚ strong base-weak acid and weak acid-strong base titrations Introduction Acid-base titrations are based on the neutralization reaction between the analyte and an acidic or basic titrant. When an acid and a base are present in a stoichiometric amount e.g. 1 mole HCl added to 1 mole NaOH‚ this means that the equivalent point has been reached in an acid-base system. The end point of an acid-base titration can be

Equilibrium and Acid Base Test Review: May 2012 Things to know: 1. Explain DYNAMIC EQUILIBRIUM. Why does a reaction at equilibrium look like it is NOT reacting? 2. Are all reactions equilibrium reactions? What assumptions do we make when we say that a reaction does NOT take place or that it is UNIDIRECTIONAL and goes 100% to completion 3. Be able to sketch a graph of the following (assuming that you start with all reactants and no products) : a. A reaction that really doesn’t do anything

ACIDS & BASES Acids/Bases Basics Acids and bases are common solutions that exist everywhere. Almost every liquid that we encounter in our daily lives consists of acidic and basic properties‚ with the exception of water. They have completely different properties and are able to neutralize to form H2O‚ which will be discussed later in a subsection. The table below compares the different properties between them: pH Scale Since acids increase the amount of H+ ions present and bases increase

When was care value base introduced? The care value base was introduced by the care sector consortium in 1992 from the national vocational qualification to support well known set of principles and values for care workers. Why was introduced? It was introduced so that people can receive their rights towards their care service and that they receive from their workers‚ and that there are fairness between every races and religions.
