Syringe Test Experiment
Formula
Word: - Calcium Carbonate + Hydrochloric acid = Calcium Chloride +
Water + Carbon Dioxide
Symbol: - CaCOз + 2HC = CaCl + H 0 + CO
Equipment: - Flask, Glass gas syringe, Bung, Marble chips (Calcium
Carbonate (CaCOз)) and tubing.
Safety
Because of the dangerous chemical that will be handled goggles should
be wore during the experiment in case any should get in your eyes
while the chemical is being measured and the experiment is happening.
Fair test
§ The amount of hydrochloric acid is the same (20ml) for every
experiment using more or less of it in each one would highly affect it
making the results erroneous and useless.
§ The same amount of marble chips is used (2gs) for every experiment
if the amount was too varied the results would be unusable.
§ The test was repeated two times to ensure fair and accurate results
from averaging.
§ Washing each apparatus that I use so that there is no pass over of
acid or other substance.
Plan
§ Starting with a 0.25 molar.
§ Fill a flask with 5cm³ 1 molar hydrochloric acid and 15cm³ of
distilled water this will reduce the molar to 0.25.
§ The Tubing should be attached to the gas syringe and the other end
put in a bung which will be eventually be inserted in the lid of the
flask (fig 1).
§ At the last second before the bung in put on top the marble chips
(2gs) should be put in to the 2.5 hydrochloric acid so to catch the
full about of gas given off and the.
§ The temperature should be checked every 20 seconds over 200 seconds.
§ To ensure for accurate results the test should be repeated multiple
times the more times it's done the more accurate the results will be.
§ Finally you should gradually change the molar from 0.25 to 2 (0.25,
0.5, 0.75, 1, 2)

To avoid contamination as best as possible, if washing hands according to SOP1 is not possible, wearing gloves and spraying with 70% ethanol is also acceptable for the procedure. Furthermore, not touching the ends of the needle and filter are absolutely essential in avoiding contamination thus applying them to the syringe whilst the ends are still in their sterile packaging will aid the prevention of contamination. When not in use placing the syringe on its plunger creates a smaller surface area for the contaminants to attach to as well. Loosening the lids of the broth tubes before placing in the Biohazard cabinet ensures easier removal when required thus less exposure time of the opened end to the environment allowing contaminants in.

According to CDC, hand washing is the only best to reduce cross-contamination. As usually as wash my hand and don gloves in order to reduce cross-contamination. I followed evidence based practice when provided morning care and later in the afternoon when I provided perineal care for the patient.

Keeping the entire instrument clean and properly storing the device are also important in terms of maintenance.

As a nursing student, it was very helpful to learn that hand hygiene – despite that we are still novices at this path – must be executed with no flaws. And this led me to recognize what areas of the hand should be covered in the technique: palm and back of the hand, thumbs, between fingers, wrists. All health professionals must wash their hands in order to avoid the transmission of microbes among patients or from an external environment to a patient. I also noticed that how missing a specific area of the hand – like thumbs – disrupts the whole idea of the process, since its purpose is to eliminate all microbes, and if any area is left out, the microorganisms from this area can migrate to another and therefore, contaminate the

This artifact is a photograph of a routine toy sanitization procedure at my child-care centre. The toys that are used by the toddlers during the day are collected at the end of the day in a mesh bag and then they are sanitized. At the end of the sanitization, the toys are taken out and dried and they are ready for use for the next day. I chose this artifact as it highlights the importance of cleaning and sanitization in the daycare. It is important to have a well-planned sanitization routine as it helps in controlling the spread of infections. Infections transmits in a cycle that consists of four parts: the germs, the host, vehicle for transmission and another host (Pimento & Kernested, 2010). The germs in the cycler can be found at any place
