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

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

Base Ball Score Card Template: Attendance: It measures whether all players of a team is present for each day. It is the main part of game to measure the performance of teams during basket ball competition. It will be helpful to store information about players. It will be stored in an excel document to fulfill the needs and requirements of players. Scorer: It keeps track information about scorer. The scorer information will be stored separately as each team score and highest and lowest score. It

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

The virtual manipulative that I ended up exploring was base blocks. The main goal of this virtual manipulative was to show students a number and have them express it through the base blocks. This manipulative ending up working better in some regards when compared to a concrete manipulative. One reason that it worked better is that it automatically checks your answer once the student has made it to the number presented‚ which cannot be done by concrete manipulatives. Another reason that it works better

Power Report Reward Power can be gained from a person’s capacity to reward compliance. When a person is rewarded or might receive a potential reward through recognition‚ a good job assignment‚ a pay rise‚ or additional resources to complete a job‚ an employee may respond by carrying through with orders‚ requests and directions. Coercive power is considered the opposite of reward power. Coercive power is considered the ability of the power holder to remove something from a person or to punish a

Macbeth and lord of the flies essay Indeed power‚ justice‚ and greed are influencing factors that can alter the course of one’s life. These themes have been represented in the following texts‚ William Shakespeare Macbeth (play on stage) and William Golding’s lord of the flies (novel). The techniques employed are‚ symbolism‚ characterisation‚ language features‚ and violence/drama. Both authors employ a number of techniques to make both texts come to life vividly and more realistic and make the audience

Acids and Bases Mirza Hasan Mammadov Acids and bases are really important in our daily day life. So let’s start with telling the definitions of them. Starting with acids‚ they are a substance which dissociates in water in order to produce one or more hydrogen ions. Also we can write H+ instead of hydrogen ion. Bases have the same definition‚ although the difference is that it firm hydroxide ions instead of hydrogen ions. We can write OH- instead of hydroxide ion. All alkali is bases but not
