natural acid‚ citric acid industry has seen a fast growth in China before 2008 due to increasing demand from both of overseas market and domestic market. However‚ in the past five years‚ China’’s Citric Acid production has been expanding slowly due to demand increase very slowly. What’’s more‚ the price of citric acid’s raw material witnessed the uptrend in the same period. What has happened in the citric market in past five years? How is the current competition structure of citric acid in China

How to make Kool-Aid There are five simple steps on how to create this candy tasting drink. Choosing the proper packet of flavoring is the first step in making Kool-Aid. Check your local grocery store’s shelf for a variety of flavors‚ from Mountain Berry Punch to Tropical Blue Hawaiian. They are very cheap‚ usually under 65 cents. After choosing the flavor that suits you‚ the second step is making sure you have the correct and necessary equipment for making Kool-Aid. You will need a two-quart pitcher

Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate this acid

recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below. As you can see from Equation 1‚ the acid-base reaction produces carbon dioxide (CO2) gas. This gas is what makes the fizzy

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

Hypothesis In this lab‚if the amount of bicarbonate of soda (2g‚4g‚8g) increases in a cupcake then the height (cm) of the cupcake will rise this is due to the fact of the reaction between the sodium bicarbonate and the acid(lemon juice) in the cake‚and as a result the cupcake will rise.Approximately 5 percent of lemon juice is citric acid‚ when an acid and a base are involved in a chemical reaction ‚ a new product is produced‚ with
