An investigation into the total acid content of assorted brands of lemon and lime soft drink

Abstract:
The aim of this experiment was to determine the total levels of carbonic acid concentration in 3 differing brands of lemon and lime soft drinks.

Research Question:
Does the acid content in three different lemon and lime flavoured soft drink brand differ significantly?
The purpose of this investigation is to calculate the total acid content within different brands of lemon and lime soft drink, to make judgments on the acidity differences in each brand.

Hypothesis:
The soft drink that contains the highest percentage of carbonic acid, such as Mountain Dew, will have the highest concentration.

Explanation of hypothesis:
It can be presumed that Mountain dew contains the highest concentration of carbonic acid as it contains more ingredients and flavourings to contribute to its taste. One of these ingredients is concentrated oranges juice which in turn contains more acid.

Introduction:
The acid quantity in many foods and drinks are a significant factor in terms of the products taste. Soft drinks are a common carbonated beverage that contains varying levels of different mixtures of acids, such like; citric acid, carbonic acid, phosphoric acid, malice acid and many more (REFERENCE). The succession of carbonated products is largely due to the addition of high levels of sweeteners within the products that may vary from high fructose corn syrup, fruit juice and sugars.
Companies in the production of making favourable soft drinks aim for the better tasting product, to which society would most prefer and incidentally buy in preference to oth-er soft drinks. This is therefore achieved by manufactures deliberately increasing the sugar and acid content within carbonated beverages to enhance the taste, texture and flavouring of soft drink. Carbonic acid is a very common ingredient used in almost all soft drinks. Essentially, carbonic acid is

    How much can we know by simply reading the nutrition facts on the back of any packaged foods? Certain nutrition facts are given and in most cases the most important or common, such as the amount of sodium, amount of protein, the total fat, and the amount of calories among others. But what guarantees that these nutrition facts given are correct or accurate? It is known that not everything on the nutrition labels may be true. Little do people know that not everything on the nutrition facts is accurate which are mandated by the U.S. Food and Drug Administration (FDA). There is a law that requires that values of specific nutrients be reported in a standardized format. This act is known as the Nutrition Labeling and Education Act (NLEA) (1).…

    From 1985 to 1997, school districts decreased the amount of milk they bought by nearly thirty percent and increased purchases of soda by one-thousand and one-hundred percent. (Roberts) About fifty-six to eighty-five percent of school age children consume at least one soft drink daily. (Roberts) Children these days are not getting enough calcium, mainly because of the large consumption of soft drinks. Instead of grabbing a glass of milk, most kids, teens and adults would rather drink soda. The effects of the preservatives and artificial sweeteners can break down the enamel on your teeth, making them prone to rotting. The reason that most people who drink to much soda have or are more prone to rotting teeth, cavities, etc., is because sugary drinks coat you teeth, gums and tongue for hours after you drink them, and most people don’t rinse or brush their teeth right after drinking soda. (Anne) When tooth decay starts to reach the nerve, the root, and the area at the base of the tooth, the tooth may die and, if let untreated, an abscess can develop. (Term Life Insurance) Drinking soda through a straw can help prevent corroding your teeth because the beverage goes straight into the back of your throat. (Anne) Soda has a pH of 2.5 to 3.0, or around…

    As much as we are more concerned of sugar content and the empty calories that soft drinks have, we must also consider the acidity of it. The corrosiveness of soda is ten times that of fruit juices, as they have this certain ingredient, called phosphoric acid. The phosphoric acids in sodas are used as an acidifying agent to give the sodas their tangy flavor. A latest research in the Academy of…

    A sign that a fruit is acidic is a sour taste. Out of all the fruits being tested, lemon is the most sour. The common assumption is that the lemon, the most sour fruit, will be the most acidic and that the banana, the least acidic fruit, will be the most alkaline. The hypothesis of this experiment fits this assumption. If the pH of different fruits mixed with saliva are tested, then the pH levels of lemon will be the most acidic.…

    The soda contain sweeteners (sugar or artificial sweeteners) flavoring, water and preservatives. Carbon dioxide (CO2) gas is added to the soda trough a high pressure process that causes the gas to dissolve into the liquid, when the soda is opened the gas is relieved and the dissolved gas escapes. In soda, the water molecules cling together around the carbon dioxide gas bubble, when the mentos dropped into the soda, the gum arabic in the coating of the mentos weakens the attractions of the water molecules around the CO2 bubbles. As soon the mentos hit the soda, the carbon dioxide forms more bubble in the tiny pores that are all mentos surface. Couple this with the speed at which mentos are sinking to the bottom of the bottle and an eruptive blast occurs as the CO2 is released and breaks free taking much of the liquid with it.…

    Soda Water Titration

    • 598 Words

    The titration experiments between the three different brands and under the five different conditions showed varied results. As shown in Graph 1, the condition which tested most effervescent was when the soda water was under cold temperatures and the least effervescent temperature was when the soda water was warm. When left standing without the lid, the soda water proved to be least effervescent. As seen in the above graph, under cold temperatures, ‘Schweppes’ demonstrated that it was the most effervescent, but under warm and room temperatures ‘Woolworths’ brand was most effervescent. When the soda water was stirred, ‘Regal’ was recorded with the highest concentration of hydrogen ions, and tied with ‘Woolworths’ when left standing with the lid removed. These results were observed because when refrigerated the gas molecules in the soda water slow down and the bond between hydrogen ions becomes strong, enabling carbon dioxide to be released (Frederick, n.d.). Whereas when the soda water was warm or room temperature, the gas molecules inside it where active and broke the bonds of the H2O chain, which in turn released more carbon dioxide, making the soda water less effervescent. Like when the soda water was left standing for 48 hours, the gas molecules would have been most active as they had no added pressure, leaving the…

    Soft drinks that commonly found in our daily life contain caffeine and sodium benzoate. The caffeine act as a stimulant and the sodium benzoate acts as a preservative of soft drink by inhibits grow of bacteria. In this experiment, hydrochloric acid is added to all solution to protonate the sodium benzoate to produce benzoic acid. Since the caffeine has no appreciable basicity, so it is neutral at pH 2. In this experiment, a spectrophotometric analysis of caffeine and the benzoic acid in soft drink is conducted to determine concentration of the caffeine and the benzoic acid mountain dew. The UV/Vis spectrometer is used and the ultraviolet absorbance is chosen to conduct the spectrophotometric analysis in this experiment.…
