    acidic. The mouth has a neutral ph that varies slightly from 6.5-7.5. This ph is maintained by buffers in the mouth, particularly in saliva. Buffers are solutions made up of either a weak acid and its salt or a weak base and its salt. They are used to resist the ph change in a solution when small amounts of acids or bases are added.…

  • Kidney Stones Lab Report

    Introduction: Kidney stones are an extremely basic urinary issue. Also known as renal calculi, kidney stones are characterized by their high occurrence and a high repeat rate. This issue results from the arrangement of insoluble salt stores in the urinary tract and inside the kidney. The rate of this issue has expanded in the course of recent years for reasons that are not entirely known, but have caught the consideration of numerous scientists. There are different types of kidney stones, each…

  • Chemistry: Sulphite And Sulfite

    Sulphite ion (SO32-) is a weak base, but undergoes some hydrolysis to produce basic solutions. In acidic solution, the equilibria are shifted to form sulfurous acid, resulting in the evolution of SO2 gas. Sulfur dioxide is a colorless gas with a characteristic choking odor. The sulfites of Na+, K+, and NH4+ are soluble in water. Most other sulfites are insoluble in water. However, due to the basic nature of SO32-, all sulfites dissolve in acidic solution. Sulphites may occur in natural waters or…

  • Essay On Cosmological Argument

    I believe that “The Cosmological Argument” for God is still quite valid, my reasons for defending this argument have been produced after a great deal of reflection on the matter, I have concluded that the argument is still quite useful. To best describe the argument, it is the conclusion that “nothing comes from nothing” as was stated by St. Aquinas, in other words God must exist because if there was nothing then we needed something to “call it into existence” so to speak. This coincides…

  • Freezing Salt Water Hypothesis

    Freezing salt-water experiment Contents: Contents, introduction and literature review on page 1. Aim, hypothesis, variables, risk assessment, materials and method on page 2. Results on page 3. Discussion and conclusion on page 4. Introduction: I have decided to do my SRP on salt water freezing because our planet is 71% water and about 96.5% of it is in the ocean which it is salt water so this is why I was interested in seeing how much salt, depresses the water from freezing. Literature…

  • Argumentative Essay On Alkaline Water

    Have you ever heard about alkaline water? Do you really know what it is? When it comes to alkaline water, you should know this water is slightly basic. It has basic minerals, including magnesium, calcium and bicarbonate. All these compounds will bind to hydrogen ions in solution, making the water more basic. Moreover, this type of water refers to its pH level, which is a number that measures how alkaline a substance is on a scale of 0-14. For example, if something will have a pH level of 1, it…

  • Phenol Degradation Lab Report

    The influence of selected variables such as pH of phenol solution, concentration of hydrogen peroxide, concentration and the volume of phenol to be treated was studied to find the degree on the degradation of phenol. The influence of these variables on the degradation of phenol using H2O2 by interpreting the TOC results is presented in the following sections. 3.1 Effect of pH The phenol degradation with different pH is shown in Figure 3. As it is clearly seen, a higher pH favors the removal…

  • 3 Component Mixtures Lab Report

    This paper describes the process by which a three-component mixture was separated and identified. The mixture was separated with the aid of a separatory funnel and various solvents acids and bases. The compound was found to be comprised of meta-nitroaniline, naphthalene, and benzoic acid / 2-napthol. All three of them are organic compounds with melting points in the order they were listed 111-114, 79-82 and 121-122/121-123 °C. the percent yield of each component was also calculated at the end…
