  • Acids And Base Titration

    Introduction: Acids and bases are often described using the Bronsted-Lowry theory which states that acids are proton donors, while bases are proton acceptors (Thorne, 78). This means that an acid has additional H+ ion(s) that can be given, whereas a base lacks these ions and will accept them. Acids and bases can further classified as strong or weak. A weak acid, such as HF, will not ionize completely, meaning that only some of the H+ ions will be lost. A strong acid will however, will release more of their H+ ions (Tro, 664). This concept is similar for bases; when strong, a base will dissociate more fully, whereas a weak base will not. Titration is a process used to identify an unknown amount of an acid or base in a solution. This is done by adding a known acid (if identifying a base), or base (if identifying an acid); in this experiment, an unknown acid, vinegar, was used (Thorne, 79). By…

  • Acids And Bases Essay

    Acids and bases are very common in today’s society, and they can be found in most households. Acids can be found as by-products of air pollution, concrete cleaner, food flavouring and is produced by the muscle. Bases are found in most cleaning products as ammonia or sodium hydroxide, and they also treat indigestion. There are many ways that acids and bases can be defined by their chemical properties. The Bronsted-Lowry definition states that acids are proton (hydrogen ion that loses its…

  • Acid Base Titration Essay

    Racheal A. Krasner Professor Garfield Beckford CHEM 1211 L 25 September 2015 Lab Report Concerning Acid-Base Titrations The purpose of this experiment was to recognize the procedures for conducting acid-base titrations. Each acid-base titration used one solution to analyze another; it also involved the use of an indicator, which denoted the endpoint of the titration. The indicator used was phenolphthalein; it produced a pink hue when the titrations reached their endpoints – between pH 8 and pH…

  • Acids And Base Titration Lab Report

    ACID-BASE PROPERTIES OF SODIUM CHLORIDE, SODIUM FORMATE AND AMMONIUM CHLORIDE INTRODUCTION The objective of this experiment is to examine the definitive characteristics of acids and bases by investigating the characteristics of strong versus weak acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base…

  • Acids And Base Titration Lab

    Introduction The objectives in this laboratory were to explore the titrations of several known acids and bases as well as observing the mole reactions of the chemical reactions that each compound undertook. The four following acids and bases were used to predict when a set amount of reactant would reach equilibrium: Hydrochloric Acid (HCl), H2SO4 (Sulfuric Acid), NaOH (Sodium Hydroxide), and Ba(OH)2 (Barium hydroxide). An unbalanced equation of each reaction was given so the balanced equation…

  • Equivalence Point Of Acid Base Titration

    the amount of base being added to the solution. The dependant variable is the indicator. The constant variable is the acid which is in the flask. When the solid acid dissolves to form ions, 1 mole of H+ ions are produced for every mole of acid being used. Molarity is used to calculate moles per liter of solution. The most dangerous part of this lab is the risk of getting…

  • Lab Analysis Of An Acid-Base Titration

    INTRODUCTION 1.1What is an acid-base titration? An acid –base titration is the determination of the concentration of an acid or base by neutralizing the acid or base with an acid or base of known concentration. An acid-base titration is the analysis of the concentration of acids and bases; through this process an acid or base of known concentration neutralizes an acid or base of unknown concentration. The neutralization of an acid or base in acid-base titration can be measured with either a…

  • Exercise 10 Acid Base Balance Essay

    Did the pH level of the blood change at all during this run? If so, how? Yes, the pH level of the blood decreased. 5. Was the pH level always within the “normal” range for the human body? If not, when was the pH value outside of the normal range, and what acid/base imbalance did this pH value indicate? No, acidosis occurred at 40 seconds when the pH dropped out of “normal” range to 7.29. 6. Did the PCO2 level change during the course of this run? If so, how? Yes,…

  • The Influence Of The Solvent On Schiff Base Ligand L, Co (2) Complex?

    3.7.1. Effect of solvent and pH The influence of the solvent on Schiff base ligand L and its metal(II) complexes were studied. The results showed that the optimal solvent for Schiff base ligand L, Co(II), Ni(II) and Cu(II) complexes were CH3CN at λemi =320, 310, 316 and 330 nm, while the optimal solvent for Mn(II) complex was DMF λemi = 312 nm, as shown in Figure 7. The effect pH on the fluorescence intensity of Schiff base ligand L and its metal(II) complexes were investigated between…
