Comparing Amount of Glucose in Orange Fruit, Grapefruit and Lemon Fruit

I have been given 4% of glucose solution, benedict's solution and
distilled water to find out the concentration of glucose of these
three juices; orange, lemon, and grapefruit.

The method of serial dilution has to be done to work out the
concentration; this is because the concentration of glucose is far too
concentrated. A dilution factor has to be worked out; I will be using
a dilution factor of 5, which means the amount of glucose and the
percentage of glucose will always divide by 2 as the dilution solution
carries on.

Theory

Orange, lemon and grapefruit are all fruits which contain
carbohydrates which include reducing sugars. Glucose is a hexose
sugar, which is a monosaccharide with six carbon atoms in each of its
molecules.

Benedict's solution is a deep-blue alkaline solution used to test for
the presence of the aldehyde functional group, CHO - which are present
in reducing sugars. Benedict's solution changes colour when a reducing
sugar is present because of a chemical reaction, which reduces the
Copper II sulphate (which is soluble) to copper I oxide, which is
insoluble and produces a precipitate. The benedict's solution changes
colour from blue to green, yellow, orange, brown and finally red - as
the amount of sugar increases.

Colorimeter

Instruments for the analysis of coloured solutions include the
colorimeter. In both these instruments, light emitted from a source
passes through the sample to be analysed, and the intensity of the
emergent beam is measured by a photoelectric device and recorded on a
milliameter. The wavelength...

Essay on Alex La Guma's The Lemon Orchard - Stable Meaning, the Perversion of Nature, and Discursive Communities in Alex La Guma's "The Lemon Orchard" South African writer Alex La Guma was an active member of his country's non-white liberation movement. One of the 156 people accused in the Treason Trial of 1956, La Guma wrote his first book, A Walk in the Night and Other Stories, in 1962 (Wade 15). "The Lemon Orchard," a story which appeared in this debut work, is a gripping piece about the horror and cruelty of racism.

Free Will in Anthony Burgess' A Clockwork Orange Essay -      Is it better to be a man choosing wrong than a man who is forced to choose right. In the classic novel, A Clockwork Orange by Anthony Burgess, a theme emerges. This is the theme of free will. Through the main character, Alex, Burgess is able to convey his ideas about free will and the oppressive nature of establishments such as governments and the media. Aside from these suggestions made by Burgess the question persists: When a man ceases to choose, is he still a man.      Free will is one of the features that separates us as humans from animals and allows us to attain intelligent thought and reasoning....   [tags: Free Will Burgess Clockwork Orange Essays] 577 words

Free Essays - Anthony Burgess' A Clockwork Orange - Banned for social reasons in many conditions and in many school systems, Anthony Burgess’s A Clockwork Orange first seems to pierce the mind with its bizarre linguistic orgy of debauchery, brutality, and sex, and for some, refuses to affect them above the level of pure voyeurism and bloodlust (either for reveling in it or despising it). Sadism seems to twist the male protagonist; his mind becomes alive with brutal fantasies whilst listening to seemingly innocuous classical music ( “There were vecks and ptitsas, both young and starry, lying on the ground screaming for mercy, and I was smecking all over my rot and grinding my boot in their litsos.”)....   [tags: Clockwork Orange Essays] 579 words

Analysis of A Clockwork Orange Essay example - Analysis and Interpretation of A Clockwork Orange A Clockwork Orange, by Anthony Burgess, is one of the most experimental, original, and controversial novels of the twentieth century. It is both a compelling work of literature and an in-depth study in linguistics. The novel is a satirical, frightening science fiction piece, not unlike others of this century such as George Orwell's Nineteen Eighty-Four or Aldous Huxley's Brave New World. However, the conflicts and resolutions in A Clockwork Orange are more philosophical than social, and its message is far more urgent....   [tags: A Clockwork Orange]

A Clockwork Orange Essay - A Clockwork Orange We are first introduced to Alex (Malcolm McDowell) in the company of his posse, strangely sipping drugged milk in a freakish bar with anatomically indiscrete manikins serving as tittie-taps and tables. The ensuing scenes flash from Alex and his three droogs brutally beating an old man to a violent rape scene to a semi-chaotic gang-brawl. The story is of Alex and his love of the old ultra-violence, his act of murder, his betrayal and imprisonment, and his cure (twice). Adapted from Anthony Burgess’ 1962 novel, A Clockwork Orange is in part a response to psychological behaviorism and the age of classical conditioning....   [tags: A Clockwork Orange Essays] 565 words
