Titration Lab How Much Citric Acid is in Your Soda? PURPOSE To determine the molarity (concentration) of citric acid (H3C6H5O7) in various different citrus flavored sodas. BACKGROUND PRINCIPLES Popular sodas all strive for a somewhat sour (’tart’) flavor and manufacturers utilize acids to impart this taste. While there are a vast variety of different brands of sodas on the market‚ they can be broken into two main categories: dark or clear. This differentiation is not only a simple color

| Peter Catalano’s Verde Vineyards in Oakville‚ California produces three varieties of wine: Merlot‚ Viognier‚ and Pinot Noir. His winemaster‚ Kyle Ward‚ has identified the following activities as cost pools for accumulating overhead and assigning it to products. For each of Verde’s fifteen activity cost pools‚ identify a probable cost driver that might be used to assign overhead costs to its three wine varieties. 1. | Culling and replanting. Dead or overcrowded vines are culled‚ and new vines

Crystallization of Benzoic Acid Purpose: The purpose of this experiment is to purify benzoic acid by crystallization. Procedure: 1. 0.5g impure benzoic acid was placed in a 50mL Erlenmeyer flask. 15mL of water was added and the mixture was heated to a boil on a hot plate. 0.5mL of water was added to the flask‚ while swirling the flask. The mixture was boiled until the benzoic acid completely dissolved. The total volume of water used was recorded. The black solid that remain in the dissolved

Running head: ACID RAIN AND ITS EFFECTS Acid Rain: The Killer Rain Twanda Banks Grantham University April 5‚ 2011 Abstract Every time you turn on the television or take a ride in a car‚ you could be contributing to a problem called acid rain. Acid Rain is a serious problem with devastating effects. Every day this problem increases. Many believe that this issue is too small to deal with‚ but if the acid rain problem is not met with head on‚ the effects on people‚ plants‚ animals‚ and the
Premium Air pollution Acid rain Sulfur dioxide
Acid rain is a common term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture to produce a rain‚ snow‚ or hail of sulfuric and nitric acids. Such pollution may also be suspended in a fog‚ or the pollutants may be deposited in dry form. Environmental damage from acid rain has been reported in northern Europe and North America. High levels of acid rain have also been detected in other areas of the world‚ such as above the tropical rain forest of Africa. Acid rain

are several purposes to the amino acid lab experiment. One reason is to help us understand the concept of acids and bases and how they interact with one another. Another purpose is to understand what occurs when placed with the existence of buffers. Lastly‚ the experiment is to help us understand the applications of titrations and how it can be used in a real world setting‚ in this case‚ the identification of an amino acid. One must understand that amino acids all have special characteristics

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

Experiment 8: Synthesis of Adipic Acid Performed November 8th & 10th By Jennifer Seitz Organic Chemistry 344 Section 803 Fall 2011 Objective: The purpose of this experiment was to synthesize adipic acid from cyclohexanol via an oxidation reaction that was catalyzed by sulfuric acid. Purity of the product was assessed by measuring the melting point. Physical Properties/Structures: Name | Formula | Molecular Weight (g/mol) | Boiling Point (0C) | Melting Point(0C) | Density(g/mL)
