Part A: Background information:
Acids and bases are currently used in many various ways in our society and it is very important in daily uses. To many industries, acids and bases are a common factor as it is used to make fertilizer, cleaning supplies, or even sources of food or medicines to provide an easy life style. Acid is a substance with particular chemical properties, acids reacts with certain metals to produce hydrogen gas, acids also reacts with carbonate and bicarbonates to produce carbon dioxide gas, it has a sour taste. Some properties of acids are, it produces H+ (as H3O+) ions in water (the hydronium ion is a hydrogen ion attached to a water molecule), Reacts with bases to form salt and water, turns blue litmus paper to red it has a pH range of between 1 and 6. According to Bronsted-Lowry theory the acids form a conjugate base after donating a proton. Base is a substance with particular chemical properties; it produces OH- ions in water, its aqueous (water) solutions conduct and are electrolytes. It turns red litmus paper to blue. Reacts with acids to form salt and water, it has pH rage of between 8 and 14. According to Bronsted-Lowry theory the base forms a conjugate acid when it receives a proton. Considering the pH scale shows how strong or weak an acid or a base is. Acids and bases can be called strong acids and strong bases when they are completely ionized when dissolved in water. Strong acids react completely with water to produce hydrogen ions H+.
For example: when looking at hydrochloric acid which is a strong acid it is combined with Hydrogen and Chlorine forming its product:
HCI H+ + CI-
Hydrochloric acid Hydrogen + Chlorine
The ions ...

Essay about Acids And Bases And Acidity In Food

- Acids and bases are not just in use in a laboratory, they come into play in the every-day, they are important to know, with respect to consumer and food products. PH scale, the potential for hydrogen ion concentration, is important because it pertains to the spectrum of acids and bases. Acids are an H+ donor and bases are a H+ acceptor. We can further identify acids by its sour taste, it turns litmus paper red, and it dissolves metals such as zinc or iron. Bases taste bitter, they turn litmus paper blue, and it has a slippery feeling....   [tags: Acid, PH, Sodium hydroxide, Base, Chlorine]

Acids And Bases Of Acid In Acid Essay

- I think that hydrochloric solution, lemon juice, and vinegar are acids because of the qualities of the substances. I know hydrochloric solution is an acid because it contains positive hydrogen ions, and lemon juice and vinegar are very sour which makes me believe they are acids. I think sodium hydroxide solution is a base because it has hydroxide ions. I think Windex, detergent, and Fantastik Cleaner are bases because they are cleaning agents which usually can neutralize acids. Water is neutral based on prior class lessons....   [tags: Carbon dioxide, Acid, Sodium hydroxide]

Acids And Bases Are Everywhere Essay

- Introduction: Acids and bases are everywhere. From things you drink to things you wash your laundry with, that item is probably an acid or a base. An Arrhenius acid is a molecular substance that when reacted with water will produce hydrogen ions(H+) as the only cations. An Arrhenius base is another molecular substance that when reacted with water will produce hydroxide ions((OH-) as the only anions. Acids and bases have different pH ranges so it isn’t hard to differentiate them. The pH of an acid will always be less than 7....   [tags: Sodium hydroxide, Acid, Titration, Base]

Effect of Acids and Bases Essay

- Effect of Acids and Bases Experiments to Determine the Effect of Acids & Bases on Different Indicators and the pH of Common Cleaning Agents The aim of the first set of experiments is to find out and record the colour changes that are observed after a certain indicator is mixed with acids and bases to form a colour reaction. Once the selected indicator has been mixed with a acid that is both weak and strong and a base/alkali that is both weak and strong we are to record the colour and choose another indicator....   [tags: English Literature Essays]

Essay on Neutralizing Acids and Bases

- The sought to determine the effects of mixing various levels of acids and bases to see which combination would have the most explosive reaction, and measure the resulting pH levels. I did this by testing an assortment of different pH levels of acids and bases, mixing them together and measuring the results. Most of the experiments resulted in a pH neutral solution, except for the Sulfuric Acid and the Sodium Hydroxide. By far, the Sulfuric Acid was the most explosive, followed by the Citric and Acetic acid....   [tags: essays research papers fc]

Effect of trans fatty acids intake on blood lipid profile Essay

- Introduction Transfatty acids (TFA) may be described as polyunsaturated and monounsaturated fatty acids holding non-coupled carbon-carbon double bonds in the trans form, disrupted by at least one methylene group(1). These trans fatty acids are formed by a process called hydrogenation to produce fats that have the firmness and plasticity desired by food manufacturers and consumers(2). Trans fats are gaining popularity in industrial sector owing to its low cost, potential to increase shelf life of products and contribute suitable features to the food(3)....   [tags: trans fatty acids]

Chemistry: Acids and Base Theories Essay

- ... He said, Aqueous solutions of acids give H+ ion. For example: NaOH → Na+ + OH−and Aqueous solutions of bases give OH- ion for example NaOH → Na+ + OH− Second description of acids and bases is found by Danish chemist J.N. Bronsted and English chemist in T.N LOWRY in 1923. According to them matter that gives protons are acid and matter that receive proton is base. With this description matters that aren’t thought to be an acid or base is now classified as an acid or a base. For example Boron trifluoride is act as an acid and forms a complex by receiving couple of electrons of Trimethylamine....   [tags: lewis’s electron theory ]

- Bases and Alkalis A base is a compound that reacts with and neutralises an acid. The reaction forms a salt plus water. Alkalis are a type of base - ones that dissolve in water. Alkalis are compounds that react and neutralise acids. Like bases, they form a salt and water in the reaction. Alkalis turn red litmus indicator paper blue and they cause Universal Indicator paper to turn blue or purple. Alkaline solutions have a pH value greater than 7.
