2:05 P.M. Purpose: The purpose of the experiment is to measure the densities of liquids. Specifically‚ the two liquids that were used and measured in the research were deionized water (H2O) and alcohol (C2H5OH). Methods: Density is an intensive quantity that cannot be visually identified. Therefore‚ the most straightforward approach to this problem was to record the measurements of mass and volume. For volume of each liquid‚ the instruments used were a 50ml burette‚ a 50ml graduated cylinder and a 10ml

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

Acid-Base Titrations A Titration of Potassium Hydroxide Phthalate and Sodium Hydroxide Hanna Piper Department of Chemistry‚ SUNY College at Brockport‚ Brockport‚ NY 14420 Chemistry 205.06 Abstract Titrations are used to find the molarity of an unknown solution. A titration begins with an analyte and titrant being used to measure the unknown molarity of the analyte. In the following experiment‚ sodium hydroxide was used as the titrant and potassium hydroxide phthalate was used as the

DRY ICE Introduction The topic I have chosen to write this report on is dry ice (also known as liquid nitrogen). This topic has quite an interest to me in a sense that I am curious about the dry ice as a whole. I have seen it being used but always thought about the manufacturing behind it. I am hopeful in finding out information such as what exactly dry ice is‚ how the dry ice is made/formed‚ what it has use for‚ and who was behind the making or discovery of dry ice. Some questions that I

EXPLORATORY RESEARCH ON LIQUID WASTE MANAGEMENTS IN VAGAMON The topic we are selected for our research is “LIQUID WASTE MANAGEMENTS IN VAGAMON”. This topic has a wide scope for research. In order to conduct an exploratory research‚ we will start doing the location analysis. For that we will collect data on the population‚ households‚ population density‚ factories‚ labours‚ sanitation‚ water reserves…etc. Based on the data collected‚ we select a sample frame where the population density is high
