buffer solutions are commonly made from a weak acid and one of its salts often sodium salt. An alkaline buffer solution has a pH greater than 7. Alkaline buffer solutions are commonly made from a weak base and one of its salts. When hydrogen ions are added to a buffer‚ they will be neutralized by the base in the buffer. Hydroxide ions will be neutralized by the acid. These neutralization reactions will not have much effect on the overall pH of the buffer solution. A. Molarity Molarity is another

Titration for Acetic Acid in Vinegar Purpose: The Primary Purpose of this Experiment is to Determine the Percent Content of Acetic Acid in a Household Bottle of President’s Choice Vinegar‚ using Titration Techniques. In addition‚ a Secondary Purpose for this Experiment that Derives Directly from the Primary Purpose is to Gain Hands On Experience in Titration Techniques‚ as a Vital Tool in our Quest to Understanding the Chemical Aspect of the World around Us. Procedure Conducting a Titration

that work by increasing the stomach’s pH balance and quickly relieving the symptoms associated with heartburn and indigestion. The pH system is a scale for measuring how acid or base is a given environment or substance. The scale goes from 0 to 14 with a pH of 7 being neutral‚ below 7 is acidic and above 7 is alkaline or base. Normally‚ the acid level in the stomach is about 2 or 3. Trouble may start when the pH drops below those numbers. An effective antacid neutralizes just enough excess acid to alleviate

Green Chris Christopher is in his last year of his degree in Agrobiology. He needs to complete a 6 months internship with the Agri-food and Veterinary Authority AVA of Singapore. He has prior experience in growing crops of tomato and achieving at least a 95% yield. In the lab‚ his supervisor Dr Ong decided to challenge him. Dr Ong said: “Hi Christopher‚ welcome to our AVA laboratory. We are pleased to have you here. We have some problems growing Rhododendron.” Christopher replied: “Thank you

A Titration is a process of the concentration of one solution being determined by its reaction with either a standard solution or a known quantity of solid dissolved in solution. It may also be used to calculate the molar mass of an unknown acid or base. Purpose: I. Prepare a standard solution of sodium hydroxide II. Standardize a sodium hydroxide solution by using potassium hydrogen phthalate (KHP) III. When given whether the acid is monoprotic‚ diprotic‚ or triprotic ‚ determine the

MEASURING pH Date of Lab: 02/09/13 Date Report submitted: 02/26/13 Purpose of the experiment By doing this experiment‚ we were trying to learn how to measure a pH with a pH meter to determine whether a solution is weakly‚ moderately or strongly acidic or basic; but also to compare the different data founded to see how the addition of certain liquid to a solution may affect the pH of the initial solution. Materials We used: * Tap water‚ distilled water‚ Soda and milk as the main
