Acid and Base Titrations: Preparing Standardized Solutions Introduction: This experiment focuses on titrations of acids and bases. A titration depends on addition of a known volume of solution and is a type of volumetric analysis. Many titrations involve either acid-base reactions or oxidation-reduction reactions. In this experiment we do one of each. We monitor the pH of the reaction with the use of a color indicator. We also learn about the standardization of bases (NaOH) and acids (HCl) which

Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore

Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus

Forensic Science Level 3 Assignment 2 Unit 2 Lisa Ashton Unit 2 Task 12 Investigating a crime scene. When investigating a crime scene before touching anything investigators must document and photograph everything‚ investigate all doors‚ windows‚ ect of any evidence of how offender got in and out of the crime scene‚ investigate every inch of the crime scene for blood‚ fingerprints‚ footprints‚ weapons‚ bullet holes‚ shell casings etc. and anything that looks out of place

BasesLewis acids and bases play an important role in chemical reactions because‚ except oxidation-reduction reactions‚ almost every reaction could be categorized as an acid-base reaction. Bases in water solutions show certain specific characteristics: bitter taste‚ feel slippery‚ and turn litmus paper blue. Acids in water solutions show these most common characteristics: sour taste‚ react with metals‚ and turn litmus paper red. The understanding of chemical reactions‚ such as acid and base interactions‚

Describe two biological therapies for schizophrenia and then evaluate each in terms of effectiveness (8 + 16 marks): One biological therapy is the use of typical anti-psychotic drugs‚ such as Chlorpromazine. The main aim of this drug is to treat schizophrenia by reducing the amount of dopamine in the brain. This is because high levels of dopamine are thought to cause schizophrenia‚ therefore by reducing the amount of dopamine‚ the symptoms of schizophrenia should reduce. Typical anti-psychotic drugs
