Titrations are typically used for acid-base reactions and redox reactions. Discover great essay examples and research papers for your assignments. CALCULATIONS Write your answers on your report sheet: A. Titration Lab Introduction The purpose of this lab is reach and be able to calculate the equivalence point when we use titration to neutralize a base with acid. One type of titration uses a neutralization reaction, in which an acid and a base react to produce a salt and water: In equation 1, the acid is HCl (hydrochloric acid) and the base is NaOH (sodium hydroxide). When writing the work's goal, you need to indicate the laboratory's topic and list the main tasks assigned to the student. Lab report example. A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption.1 The titration of KHP with NaOH was the standardization process which determined the actual concentration of NaOH.

Angelica Rodriguez 05/14/13 Period 4 Acid-Base Crime Scene Titration Introduction: Titration is a lab technique used to determine the exact concentration of an acid or base. Skills of titration techniques. CHEM 1A Lab, Department of Chemistry, California State University, Fresno, CA 93740 Carmenchick@mail.fresnostate.edu September 23, 2017 The purpose of this experiment was to determine how much KMnO4 was needed to titrate approximately 1 mL of an Unknow X101 … 2. In aqueous solutions, a It involves reacting a solution of known concentration with one of the unknown concentration, in order to determine the equivalence point”. Trial 1* Trial 2 Trial 3 Initial volume [mL] 16.60 0.60 16.40 Final volume [mL] 32.30 16.40 32.18 Volume added end-point [mL] VNaOH 15.70 15.80 15.78 Table 2. It is providing brief theoretical information. To find the molarity (molar concentration) of the NaOH solution: 0.01600 L HCl x 0.184 moles HCl = 0.00294 moles HCl (3) 1 L solution 0.00294 mol HCl x 1 mole NaOH = 0.00294 moles NaOH (4) 1 mole HCl The results were then used to determine the exact concentration of the original HCl sample. 25.0ml HCl (aq) was pipetted into a 100ml conical flask. 250 volumetric flask
The, Introduction: 10mL measuring cylinder
SCH3U. understanding chemical reactions (see Tro, pp 167-171). A standard solution can be prepared in either of two ways: A primary standard is carefully weighed, dissolved, and diluted accurately to a known volume. Introduction An understanding of the properties of acids and bases is an essential part of Procedure. Lab Titration – Titration Lab Report Calculations is free lab report sample. It involves measuring the exact volume of a solution with a known concentration that will react with a measured volume of a solution that has an unknown concentration. Lab Report On Redox Titration 1165 Words | 5 Pages. A titration is the controlled addition of a solution of known concentration (the titrant) in order to determine the concentration of a solution of an unknown concentration. Web. Hire verified expert $35.80 for a 2-page paper. compound that produces H+ ions upon dissolution, For this experiment, a series of strong acid-strong base titrations were performed to determine the unknown solution concentration of HCl. In this laboratory experiment, the crime scene analyst will use their knowledge of acids and bases to determine the concentration of each acid found as evidence in a murder. I. Acid-Base Titration A standardized KMnO4 solution was used on a known solution of Oxalic acid to help determine the unknown percent oxalic acid in unknown X101. Quant 320L
