Chemistry Personal Statement Essays

Chemistry Personal Statement Essays Chemistry Personal Statement Essay Chemistry Personal Statement Essay Students who are studying their Masters course would already know the significance of writing an appealing Chemistry personal statement. They have had their share of experience of writing these difficult statements just like any other undergraduate. A personal statement or a statement of purpose helps the applicant in distinguishing his application from dozens of other candidates who have applied for the same course. It provides a huge opportunity to the candidate to leave aside his academic test scores and impress the board with his/her unique skills, qualities and personality. Even a student with high test scores or GPA cannot certainly feel confident in getting the seat in the university. Therefore, the only way one can ensure a seat in the university is by setting himself apart by submitting an appealing and attractive chemistry personal statement. Dozens of applications get rejected each year because of poorly written content and poorly defined thoughts. Students will only be able to impress the board of the university if they consider it carefully what sorts of ideas should be included in the statement and how to express those ideas in an appealing manner. This may probably seem quite intimidating at first but once you sit down and pen down those ideas in a proper order you will see that how easy it is to write a good statement. It is also recommended that every applicant should make an outline so that he can gather and express his thoughts in an effective manner. First outline the introduction of the statement and consider including those important elements in it that can catch the attention of the board. For example, you can start with your childhood dream to become a chemical engineer. While outlining the elements that are to be included in the body section of the statement, consider those points that needs a complete description. For instance, you can link the academic qualification with your interest in the chemistry field and how that qualification can help you become a great chemical engineer. You can also include any experiences that you have gained in this field after completing the undergraduate course. Remember that four important elements that a great personal statement includes such as the applicant’s motivation for seeking chemistry degree, his aspiration, work experience and qualities that relates to that field. While writing a personal statement keep one thing in mind that you need to put forth evidence of your skills and qualities that you claim to possess. You can use that outline to create the first draft. Do not edit the draft while writing because editing and revision can be done later. Do not worry about anything and just let your creativity do the work. Once the statement is completely written, revise it and see if it meets with the given word count requirement.

How to Make Your Own Invisible Ink

How to Make Your Own Invisible Ink Making invisible ink to write and reveal secret messages is a great science project to try, even if you think you dont have the right chemicals. Why? Because just about any chemical can be used as invisible ink if you know how to use it. What Is Invisible Ink? Invisible ink is any substance that you can use to write a message that is invisible until the ink is revealed. You write your message with the ink using a cotton swab, dampened finger, fountain pen, or toothpick. Let the message dry. You might also want to write a normal message on the paper so that it doesnt appear to be blank and meaningless. If you write a cover message, use a ballpoint pen, pencil, or crayon, since fountain pen ink could run into your invisible ink. Avoid using lined paper to write your invisible message for the same reason. How you reveal the message depends on the ink you use. Most invisible inks are made visible by heating the paper. Ironing the paper and holding it over a 100-watt bulb are easy ways to reveal these types of messages. Some messages are developed by spraying or wiping the paper with a second chemical. Other messages are revealed by shining an ultraviolet light  on the paper. Ways to Make Invisible Ink Anyone can write an invisible message, assuming you have paper, because body fluids can be used as invisible ink. If you dont feel like collecting urine, here are some alternatives: Heat-Activated Invisible InksYou can reveal the message by ironing the paper, setting it on a radiator, placing it in an oven (set lower than 450 F), or holding it up to a hot light bulb. To write the message you can use: Any acidic fruit juice (e.g., lemon, apple, or orange juice)Onion juiceBaking soda (sodium bicarbonate)VinegarWhite wineDiluted colaDiluted honeyMilkSoapy waterSucrose (table sugar) solutionUrine Inks Developed by Chemical ReactionsThese inks are sneakier  because you have to know how to reveal them. Most of them work using pH indicators, so when in doubt, paint or spray a suspected message with a base (such as sodium carbonate solution) or an acid (such as lemon juice). Some of these inks will reveal their message when heated (e.g., vinegar). Examples of such inks include: Phenolphthalein (pH indicator), developed by ammonia fumes or sodium carbonate (or another base)Thymolphthalein, developed by ammonia fumes or sodium carbonate (or another base)Vinegar or diluted acetic acid, developed by red cabbage waterAmmonia, developed by red cabbage waterSodium bicarbonate (baking soda), developed by grape juiceSodium chloride (table salt), developed by silver nitrateCopper sulfate, developed by sodium iodide, sodium carbonate, potassium ferricyanide, or ammonium hydroxideLead(II) nitrate, developed by sodium iodideIron sulfate, developed by sodium carbonate, sodium sulfide, or potassium ferricyanideCobalt chloride, developed by potassium ferricyanideStarch (e.g., corn starch or potato starch), developed by iodine solutionLemon juice, developed by iodine solution Inks Developed by Ultraviolet Light (Black Light)Most inks that become visible when you shine a black light on them also would become visible if you heated the paper. Glow-in-the-dark stuff is still cool. Here are some chemicals to try: Dilute laundry detergent (the bluing agent glows)Body fluidsTonic water (quinine glows)Vitamin B-12 dissolved in vinegar Any chemical that weakens the structure of paper can be used as an invisible ink, so you might find it fun to discover other inks around your home or lab.
