Hoitt CHEM 105 Lab 11/29/2012 Lab # 11 – Acid - Base Titration Introduction: The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions are made up of solvents and solutes

VIBRATIONAL-ROTATIONAL SPECTRA OF HCl Physical Chemistry Laboratory II‚ CHEM 3155.001 April 20‚ 2012 Introduction and Objective The experimental objective of this lab was to collect an IR spectrum of gaseous HCl and from it the experimental rotational constant‚ B‚ and fundamental vibration frequency‚ v0‚ can be calculated(1). The concept of infrared spectroscopy deals with the infrared region of the electromagnetic spectrum. Molecules absorb at specific resonant frequencies that are characteristic

Given the evidence‚ it can be determined that a reaction will occur when reactants have a kinetic energy greater than the activation energy‚ this is a theory of collision theory. For example‚ in the first experiment‚ the test tube filled with 10 mL of 3% hydrogen peroxide and had scoop of manganese dioxide‚ had a greater reaction than the other test tube. Which simply contained 10 mL of 3% hydrogen peroxide. The factor that affected the reaction rate was that the manganese was seen as a catalyst.

Rate of Reaction Experiment Introduction : in this term in chemistry class I was learning about rate of reaction. As defined by the Britannica encyclopedia‚ a chemical reaction is a process where one or more substances (reactants) are converted to one or more different products because of the rearrangement of atoms of the reactants. For the reaction to occur‚ the particles must collide with each other and in order to succeed there must be enough energy for the collision because a collision with little

accomplish the following objectives. The first objective aims to synthesize an isomer of alkenes. This was done by converting maleic acid to fumaric acid. This conversion was accomplished by applying a heat-catalyzed reaction on maleic acid diluted in distilled water and mixing it with HCl using a reflux set-up. A reflex set up is a distillation set up wherein the set up differed because it is inverted vertically. This was done in order to break the pi bond to allow the rotation about the remaining sigma

Investigating The Rate Of Reaction Between Marble Chips And Hydrochloric Acid Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation

Lab #4: Aqueous Reactions Introduction: In this experiment we studied the two different types of aqueous chemical reactions‚ double replacement and single replacement. In a double replacement reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when
