DETERMINATION OF FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low‚ because of low sugar content and high fruit acid content‚ this makes the fruit taste sour. During the ripening process the fruit acids are degraded‚ the sugar content increases and

A. Title – Acid-Base Extraction with Separatory Funnel B. Introduction – The main objective of the experiment was the extract an acid‚ a base‚ and a neutral compound from a 2:1:1 compound of benzoic acid‚ p-nitroaniline‚ and azobenzene. In theory‚ an extraction technique based on phase distribution should allow two immiscible solvents to separate with a portion of the solute distributed into each. Using a separatory funnel‚ acids were extracted with bases (NaOH)‚ and bases were extracted

In the melting pot of cultures in the United States‚ Hmong people are among the most misunderstood and enigmatic ethnic groups. Throughout history‚ during the most uneasy and difficult time‚ when Laos experienced civil war in the 1950s and 1960s‚ the Hmong sided with the government‚ fearing a communist regime would disrupt their independence. The Vietnam War resulted in the Hmong to siding with the United States to oppose Vietnamese and Laotian communists‚ lose a huge percent of their population

For a long time‚ the research of foreign direct investment and trans-corporation mainly confine to the enterprises of manufacturing industry and most theories of international production are only fit for goods procuction. However‚ the fast development of service economy can’t permit us to ignore fact again‚ can’t permit our research to be only limited to the goods‚ but leave the question open to service. Gratifiedly‚ this kind of state is changing. On one hand it is because people have realized the

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

Fractional Distillation of a Binary Mixture Introduction: In this experiment the aim is to separate two chemicals from a stock mixture (azeotrope) using two different distillation processes. In both methods (simple and fractional) the liquids reach a boiling point‚ the molecules then vaporize‚ separate from the stock mixture and then condense back into liquid form down the to the receiver. Simple distillation works well when the two components boiling points have a large difference. Fractional

was to prepare Benzilic acid by multistep synthesis starting with benzaldehyde. In this setup however‚ product of the first step‚ Benzoin‚ is provided thereby omitting the first step involving the conversion of benzaldehyde. For this experiment‚ the microscale techniques of reflux‚ crystallization‚ and melting-point determination were used. Utilizing these techniques a product yield of 93% for benzil and 57% for Benzilic acid was obtained‚ as well as a melting point range of 94.8 – 95.4oC for benzil

Free range farming can be controversial. It is expensive‚ but also offers a better life for animals. In this discussion you will be informed about the good side of free range farming‚ the negative aspects of free range farming. I will also inform you about the costs of both. There are a lot of good things about free range farming. One of many is that in the time span that the animals are living‚ they get a decent life. They get to interact with other animals and live a life like normal animals

DISTILLATION ABSTRACT Distillation‚ one of the most significant method for separating a liquid mixture and its components‚ is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity

and industrial applications. Citric Acid is one of the organic acids commonly used as a chelating agent. It is considered an excellent chelating agent that binds metals. It is used to remove lime scale from boilers and evaporators. It can be used to soften water‚ which makes it useful in soaps and laundry detergents. By chelating the metals in hard water‚ it lets these cleaners produce foam and work better without need for water softening devices. Citric acid is the active ingredient in some bathroom
