is not in the normal blood pH‚ the person can fall sick and it might be harm to the person. The maintenance of blood pH is called acid-base homeostasis. Acid-base homeostasis is a complex synergy that involving lungs‚ kidneys and a buffer chemical in blood and blood cells. BACKGROUND A substance that has high concentration of hydrogen ion in solution is called acid and solution that has low concentration of hydrogen ion is base. Base

DNA is a double helix molecule that contains information that is used to make up a person’s body. DNA controls every aspect of a person’s body from their eye and hair color‚ height‚ and other features. DNA’s specific and unique characteristic can be crucial when solving a crime. DNA can be used to convict a suspect or exonerate an innocent person. When DNA is found it is even more important that is handle properly to ensure proper identification and accuracy of testing. The evolution of DNA technology

Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding

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 solutions as

Acetic acid‚ a pungent smelling colourless liquid having sour taste‚ used very commonly in the chemistry laboratories. It got its name from Latin word Acetum‚ which means vinegar. Pure acetic acid is also called glacial acetic acid‚ because in winters it freezes easily as temperature goes below 16-17°C. Therefore it looks like as if a small glacier is there in the bottle‚ hence called glacial acetic acid. Laboratory and daily life uses of acetic acid are: (i) Acetic acid is used in household kitchens

Sulfuric Acid is one of the the important chemical compounds. A Great amount of sulfur is mined all around the world and is used to produce sulfuric acid. Sulfuric acids being produced Sulfuric acid may seem like something to find in a lab‚ perhaps under the label “corrosive‚” and in some kind of tube that isn’t affected by it. But‚ in reality‚ it’s quite common‚ and is used often in the industrial business‚ for many different objects. Because of this‚ many places can often be judged upon their

ACID BASE TITRATION OBJECTIVES 1. To demonstrate the basic laboratory technique of titration 2. To learn to calculate molarity based on titrations INTRODUCTION Molarity (M) or molar concentration is a common unit for expressing the concentration of solutions. It is defined as the number of moles of solute per liter of solution (or millimoles of solute per milliliter of solution). The concentration of a basic solution can be determined by titrating it with a volume of a standard acid solution (of
