  • Bases and Alkalis

    601 Words  | 3 Pages

    Bases and Alkalis A base is a compound that reacts with and neutralises an acid. The reaction forms a salt plus water. Alkalis are a type of base - ones that dissolve in water. Alkalis are compounds that react and neutralise acids. Like bases, they form a salt and water in the reaction. Alkalis turn red litmus indicator paper blue and they cause Universal Indicator paper to turn blue or purple. Alkaline solutions have a pH value greater than 7. Alkaline solutions feel soapy and are

    PURPOSE To investigate the reactions of a typical acid (dilute hydrochloric acid) with metals, metal oxides, carbonates and bases. APPARATUS The following materials in order to complete this experiment: Dropper bottles containing 0.1M solutions of hydrochloric acid or limewater (calcium hydroxide) and sodium hydroxide. Dropper bottle of bromothymol blue indicator Small samples of the following metals: zinc, copper turnings, magnesium and iron Copper (II) oxide powder Magnesium oxide

  • Effect of Acids and Bases

    Effect of Acids and Bases Experiments to Determine the Effect of Acids & Bases on Different Indicators and the pH of Common Cleaning Agents The aim of the first set of experiments is to find out and record the colour changes that are observed after a certain indicator is mixed with acids and bases to form a colour reaction. Once the selected indicator has been mixed with a acid that is both weak and strong and a base/alkali that is both weak and strong we are to record the colour and choose

  • Understanding Acids and Bases

    3020 Words  | 13 Pages

    Part A: Background information: Acids and bases are currently used in many various ways in our society and it is very important in daily uses. To many industries, acids and bases are a common factor as it is used to make fertilizer, cleaning supplies, or even sources of food or medicines to provide an easy life style. Acid is a substance with particular chemical properties, acids reacts with certain metals to produce hydrogen gas, acids also reacts with carbonate and bicarbonates to produce carbon

    Question: What is the effect of acids and bases on apple oxidation? Background Information: Apple discoloring, is the process of the skin turning brown when bruised and exposed to air. The browning is due to oxygen, O2, reacting with chemicals which breaks down the cells in the fruit. The reaction is called enzymatic oxidation a process that is started by the enzymes that are present in the apples which starts the browning process of the apple. However, the enzymes are quickly destroyed by chemicals

  • Neutralizing Acids and Bases

    The sought to determine the effects of mixing various levels of acids and bases to see which combination would have the most explosive reaction, and measure the resulting pH levels. I did this by testing an assortment of different pH levels of acids and bases, mixing them together and measuring the results. Most of the experiments resulted in a pH neutral solution, except for the Sulfuric Acid and the Sodium Hydroxide. By far, the Sulfuric Acid was the most explosive, followed by the Citric and Acetic

  • Chemistry: Acid-base Titration

    502 Words  | 3 Pages

    Chemistry: Acid-Base Titration Purpose: The objective of this experiment were: a) to review the concept of simple acid-base reactions; b) to review the stoichiometric calculations involved in chemical reactions; c) to review the basic lab procedure of a titration and introduce the student to the concept of a primary standard and the process of standardization; d) to review the calculations involving chemical solutions; e) to help the student improve his/her lab technique. Theory: Titration was

  • Acid-Base Titration

    411 Words  | 2 Pages

    Acid-Base Titration I. Abstract The purpose of the laboratory experiment was to determine equivalence points, pKa, and pKb points for a strong acid, HCl, titrated with a strong base, NaOH using a drop by drop approach in order to determine completely accurate data. The data for this laboratory experiment is as follows. Using a concentration of .1 NaOH we had the largest NaOH volume before the largest pH increase at 6.38ml. For the largest NaOH volume after the largest pH increases

  • Chemistry: Acids and Base Theories

    671 Words  | 3 Pages

    INTRODUCTION Acids and bases always challenged me throughout the years of learning them so when I learned I am going to face this topic again I thought it will be the best idea to a experiment for learning better therefore my aim for this project was learning the fundamentals of this topic. Acids and bases are really important in functioning cell. Majority of them are harmful and they destroy tissues by dissolving protein. For example, sulfuric acid is a strong acid and it has ability to hold the

  • Arrhenius Theory Of Acids And Bases

    classified into two different substances. These two substances are acids and bases. The Arrhenius Theory of acids and bases states that acids are substances that dissociate to form charged atoms known as ions. Bases ionize to produce hydroxide ions while acids produce hydrogen ions. HCl is an example of an Arrhenius acid because it dissociate into an H+ ion. The reaction involving NaOH is an example of an Arrhenius base because it is increasing the concentration of (OH-) ions. The reaction which
