Neutralization experiment AIM:- To investigate how heat is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl)‚ Sulphuric acid (H2SO4) etc. An alkali is a

The Identification of Bacillus Badius [pic] Hannah Melanchuk Dr. Robert Suran May 1 2013 Microbiology Abstract Over a three week time span I was able to successfully identify an unknown microorganism by combining the results of several tests. The first test was the Gram stain test which showed the microorganism was Gram positive and rod shaped. Using an Unknown Identification Flowchart‚ I proceeded to inoculate a Starch plate. In week 2‚ I

Testing Vinegar – Acid Base Titration Aim The aim of this practical experiment was to pair up and measure the concentration of the acid in three different brands of vinegar. We added a base liquid‚ to the three different brands of vinegar until a neutralization reaction occurred. We conducted the experiment using the titration method. Hypothesis My hypothesis is that the vinegar that will have the highest acidic level will be Cornwell’s because it is known for being free from artificial colours‚ flavours
