Billy Kong Chem&163 Lab Report 1 Analysis of Acids‚ Bases‚ pH and Salt Purpose: Explore various methods for determining the characteristics of acid/base solution. The goal of this experiment include the investigation of various acid/base indicators‚ calculating the change of pH with concentration‚ change of pH due to the addition of salt and different between strong and weak acids/bases. Safety and Disposal: Use extreme caution when handling concentrated acids and bases. Dispose of all

IMPROVED ASSAY This essay aims to critically compare and contrast the community psychology and public health approaches to social problems. It is imperative however to first explain what these two concepts mean before executing on how they compare and differ from each other. It would also be of significance to know how these concepts where established.

Background An indicator is a halochromic chemical compound that is added to a solution to determine its pH. It is a chemical detector for hydronium ions. The indicator changes colour to show the pH of the solution. Some indicates are not very precise and only tell us whether the solution is acidic or basic. When the indicator is added to the solution‚ they bind to hydrogen or hydroxide ions. The different electron configurations of the bound indicator cause the indicator ’s colour to change.

A pH meter is an electronic device used for measuring the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. A colorimeter is a device used in colorimetry. In scientific fields the word generally refers to the device that measures the absorbance of particular wavelengths

University Physics Professor Marc Favata How does Human Activities have an Effect on Climate Change? "Humans are almost entirely the cause" of climate change‚ according to a scientist who once doubted that global warming even existed. As many scientists and physicists across the world believe that human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases‚ aerosols (small particles)‚ and cloudiness. A recent report of the

There are a lot of activities to enjoy around us. We are able to divide two type of activities such as indoor activities and outdoor activities. Some people like outdoor activities such as a baseball‚ football. Others like indoor activities such as volleyball‚ table tennis. In case of indoor activities‚ regardless of weather‚ people want to play sports‚ they can enjoy them. However‚ I prefer playing outdoor activities. There are two reasons why I think so. First‚ outdoor activities help people to be
