I. Introduction The purpose of this experiment is to determine the pH values of acids‚ bases‚ and buffers of distilled water and 10.0 buffer using measured concentrations of Sodium hydroxide (NaOH) and/or Hydrochloric acid (HCl). Acid is a compound typically having a bitter taste and capable of nullifying alkalis and releases hydrogen ion when added to a solution‚ or containing an atom that can accept a pair of electrons from a base (McKinley‚ Dean O’Loughlin‚ & Stouter Bidle‚ 2016). Bases are water-soluble

Title: Studying the Effect of types of Food on a Betta Fish’s growth Introduction: Before you consider buying an animal or pet for the first time‚ you should probably to some research on that animal as we did. It’s very important to know what they eat‚ their environment‚ and also what you shouldn’t do for the health and safety of your fish. For instance‚ our fish cannot eat regular goldfish food. We wanted to test out how the types of food effect the growth. As a control‚ we went for something

Negative effects on teenagers in the fast food industry Competition within the fast food industry is a difficult challenge which can take a toll on the youngest employees: teenagers. The very nature of the industry can sometimes harm teenagers in the process of producing profits. Inexpensive labor is considered essential for competing in the industry‚ but some of the young teenagers may become victims of exploitation. Some companies target the young and poor demographic and can guide them to

Temperature and pH will both effect and change the active site of an enzyme. Denaturing‚ the changing of the shape of an enzyme‚ will occur if a big enough change in temperature and pH to go away from that enzyme’s optimal conditions. Each enzyme has optimal conditions which is the best temperature and pH for that enzyme to function. When temperature and pH move away from those conditions the enzyme could slow down its rate of activity

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

greatest global crisis facing humanity in the twenty-first century. Overpopulation is the major global problem because of several reasons. Most of the problems we have today‚ such as ocean depletion‚ food shortages‚ water shortages‚ air pollution‚ water pollution‚ and global warming are the effects of overpopulation. The more people there are‚ the more resources consumed and the more waste created. A child born today in the United States for instance will produce fifty-two tons of garbage and consume

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.

Food additives are substances that are added to the food. They serve as different functions such as preservation‚ flavorings and colorings‚ antioxidants‚ and stabilisers. They are added in the manufacture process intentionally or unintentionally. There are many different food additives‚ and they can be classified as natural or artificial. Most food additives are naturally occurring‚ and some may even be beneficial. The common natural food additives such as citrus acid and ascorbic acid‚ for example

Food adulteration is the act of intentionally debasing the quality of food offered for sale either by the admixture or substitution of inferior substances or by the removal of some valuable ingredient. Food is declared adulterated if: • a substance is added which depreciates or injuriously affects it • cheaper or inferior substances are substituted wholly or in part • any valuable or necessary constituent has been wholly or in part abstracted • it is an imitation • it is coloured
