Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

in developing countries the economy is poor and they don’t have the resources to maintain the originality of these artefacts. The Elgin Marbles‚ a significant denominator of Greek History‚ are a present concern under the debate‚ ‘Who owns the past?’ generally between curators and the Greek government. Initially‚ the Greeks held possession of the Elgin Marbles‚ in Athens but they were removed by the British Lord

build and evaluate the performance of a marble launcher‚ this is done by first finding the velocity of the marble using the equation v2=u2+2as‚ this will be done by conducting an experiment to first find the vertical distance (s) the marble travels and acceleration due to gravity (a). This will then be used to find the time the marble will travel for at angles of 30o‚ 45o and 60o using the equation v=u=at‚ rearranging this equation to find the time the marble will travel at will become‚ .

Chemistry Lab Report Stoichiometry Design Experiment Percentage Yield of Calcium Carbonate and HCl I. Background Information When marble chips and hydrochloric acid are added together‚ they form sodium chloride‚ water‚ and carbon dioxide. This reaction can be displayed by the balanced equation below; CaCO3 (s) + HCl (l) NaCl(s) + H2O(l) + CO2 (g) As the carbon dioxide is formed‚ it will leave the open beaker as a gas. This will result in a loss of mass. The mass change can then be

Acid Base And Salt Acid Acids:- The word ‘Acid’ came from Latin word ‘Acidus or Acere’ which means sour. Sour taste is the most common characteristic of acid. Acid turns blue litmus paper red. There are many substances which contain acid and hence taste sour‚ such as curd‚ tamarind‚ lemon‚ etc. Types of Acids:- Acids are divided into two types on the basis of their occurrence – Natural acids and Mineral acids. Natural Acid:- Acids which are obtained from natural sources are called natural
