Fizzy drinks can cause some significant damage to your teeth and general heath. There are three main damaging factors: the sugar content, the acidic properties and the staining effect. The ph of a solution is defined as the hydrogen ion, H+, concentration of said solution (ThoughtCo, 2017). The ph scale ranges from 0-14. Ph 7 being a neutral ph, every ph above being classed as alkali and every ph before being classed as acidic. The mouth has a neutral ph that varies slightly from 6.5-7.5. This…

Questions 1. Why are three replicate titrations done for each sample? Three titrations are performed because an error may occur in one of the titrations and getting two extra titrations can help eliminate the wrong answer. It is also a great way to practice accuracy and precision. 2. What other household products could be analyzed by titrations (suggest three)? Some other household items that could be analyzed by titrations are fruit juice, Cola beverages and household ammonia. 3. Why is it…

Buffers are substances that help reduce the changes in concentrations of ions which are known as hydrogen ions and hydroxide ions. The composition of a buffer in an acidic aqueous solution is combined containing a weak acid and salt of conjugate base of the weak acid. (Importance of Buffers, 2013) The composition of a buffer in a basic aqueous solution is combined containing a weak base and a salt of conjugate acid of weak base. A buffer solution resists the changes in pH therefore resisting…

With this experiment intend to prove Salem Lakes ability to buffer chemicals used in the water treatment process versus that of the Yadkin River. Using a jar test machine, simulated the addition of an acid in the form of Al2SO4, and a base NaOH to the coagulation process. Salem Lake does show a preferred buffering at higher acid doses, though Yadkin River is more efficient at the low to mid-range dose. INTRODUCTION There is a distinct difference in the buffering capacity of Salem Lake versus…

In the “Intrinsic and Extrinsic Motivations” section, a quotation stood out most to me, “You play the game of school to win against your competition, not to learn. (Bain 46). This stood out to me most because I wonder when did school turn into a constant competition? How would one see himself or herself as a winner, without learning? I thought of my high school, with a larger graduating class of 248 students; we all were competitive. A vast majority of us were participating in sports, while…

enters/leaves from her car to shop. The idea is that women cannot live a normal life without being paranoid of rape or physical harm. Not only did women fight for decades for equal rights but now, women fight for their safety and freedom from men. There is a constant battle between the men and women. Due to the privileges that gender affords them, men do not have to worry about their daily lives and their fears are vastly different from those of women. First, the manner men conduct their day…

Even people in power can be driven by their feelings, and commit unethical choices. Morals can be discarded easily due to heighten desires. Desires can be a strong force in humans. As shown in the story, “Death Constant beyond Love” by Marquez, where Senator Sanchez feelings of desire overtook his rational thoughts. Senator Sanchez was given six months and eleven days to live, which was kept as secret to himself. The Senator believed he had found the woman of his…

Figure1.3: Band gap vs lattice constants diagram for hexagonal nitride compounds. The typical of measured band gap bowing for ternary alloys AlGaN and InGaN is shown by the solid line track[21]. 1.4. Unique Material properties of Gallium Nitride: The unique material properties of GaN engraves it as an prominent semiconductor material for many electronic and optoelectronic devices[18]. • The wide and direct energy band gap sorts GaN as an appropriate materials for device fabrication in the field…
