- An acid is a substance that produces H+ to form a solution that has a pH <7. It turns litmus paper red. It reacts with bases to form a salt and water. A weak acid is an acid that dissociates incompletely, releasing only some of its protons(H+). A strong acid is an acid that fully dissociates incompletely, releasing only some of its protons(H+). A base is a substance that can accept (H+) and releases(OH-) to form a solution that has a pH>7. It turns litmus paper blue. It reacts with acids to form a salt and water....

- Determining the Concentration of Citric Acid Introduction Titrations are performed to calculate the unknown concentration of solutions using standard solutions. A solution of known concentration and volume is added to a solution of known volume and unknown concentration, a burette is used to find the exact amount of the known solution is required for the reaction to come to completion. A pH indicator is used to determine when a reaction has completed. Aim To determine the concentration of Citric acid in both fresh and bottled lemon juice....

- Investigating the Concentration of Citric Acid Problem ------- I have been set the task of determining the concentration of a sample of citric acid, using only a 1.0 M solution of sodium hydroxide and any laboratory glassware that is required. I have also been given the RMM of citric acid as 210g and I have been told that one mole of citric acid will react with 3 moles of sodium hydroxide. My Experiment ------------- Using this information I have determined that the best way to conduct this experiment is to do a titration.... [tags: Papers]

- Analysing the Ethanoic Acid Concentration in Different Types of Vinegars Vinegar is a mixture of various acids, ethanoic acid being the most abundant. Most vinegars are made from a sugary liquid, this liquid is fermented to produce ethanol and then oxidised to form ethanoic acid. Different vinegars use different sugary liquids and this could lead to variation between the vinegars. My aim in this investigation is to discover whether the concentration of ethanoic acid varies between vinegars.... [tags: Papers]

- The Differences between Strong acid and Weak Acid Titration Introduction: This experiment is to explore the certain properties of strong acid (HCl) and weak acid (HCOOH) and how these properties make effects on titrations. The first is to find out the properties and differences of strong acid using phenolphthalein measurement and curve measurement. The second step is to find out the properties and differences of weak acid using phenolphthalein measurement and curve. The final step is to compare the salts that produced....

- Discussion 19 The purpose of this experiment was to synthesize and purify of Aspirin and Oil in wintergreen. While determining the purity through analytical techniques. During the first part of the lab the crude sample of acetylsalicylic acid, Aspirin, was synthesized. The synthesis of Aspirin shows a general trend of chemical reactions known as esterification reactions. The compound containing a hydroxyl group reacts with a compound containing a carboxylic acid group, producing an ester molecule and water.... [tags: Aspirin, Carboxylic acid, Salicylic acid]

- A titration is used to determine the amount of acid in a given solution. This is done by titrating a measured volume of acid (in this instance, acetic acid (CH3COOH)) with a solution of a strong base (usually sodium hydroxide (NaOH)), of a known concentration. The NaOH is added in small aliquots until the acid has been neutralised, and this can be determined with an indicator dye, such as phenolphthalein, or a pH meter (Nelson & Cox, 2008 pg58). In this practical, a pH meter was used and this allows for the acidity or alkalinity of a solution to be measured, and this was more accurate than using an indicator dye....

- Fat: My overall fat intake did fall into the AMDR, of 20%-35%, at 33.5%. My report also showed my intake of omega-3 and omega-6, also known as alpha-linolenic acid and linoleic acid. I did not meet the recommendation for either one of these. The recommendation for omega-3 is 1.1 gram; I took in only about 0.02 grams. While the recommendation of omega-6 is 11 grams, I only consumed about .28 grams. Both of these fatty acids are essential to growth. Omega-6 is metabolized in the body and turned into arachidonic....

- Acid Rain Acid rain has become an environmental concern of global importance within the last decade. With the increasing environmental awareness of the "unhealthy" condition of our planet earth the concern about acid rain has not lessened. In brief, acid rain is rain with pH values of less than 5.6. When dealing with acid rain one must study and understand the process of making Sulfuric acid. In this project we will take an in depth look into the production of sulfuric acid, some of its uses and the effects of it as a pollutant in our environment....
