Most Efficient Antacid Investigation
Aim-
To see which antacid tablet is the most efficient out of 4 samples.
Plan-
To do this experiment I will see how long it takes acid to neutralise
each antacid tablet by titration. Neutralising a substance is when you
find the point when it's neutral by using another substance with the
opposite pH. I will conclude that the one that takes the longest to
get to its neutral point is the most efficient tablet. Because I will
be handling dangerous chemicals I will wear such safety gear as gloves
to stop the acid going on my hands and goggles to stop it from going
in my eyes, if the acid goes anywhere else on my body or clothes I
will stop my current experiment immediately and wash the acid off with
water.
Fair Test-
To make this fair I will have to use constant measurements throughout
all the tests so that a result doesn't become distorted or anomalous.
I will use the same equipment for all the tests so that all my results
will remain similar, and I will also wash all my equipment after each
test with distilled water (this water's pH won't affect the next test,
as it's neutral). This will men that any chemicals from the previous
test won't affect the next one.
Preliminary prediction-
From what I know now I can only predict that the tablet with the most
alkali substance will take the most acid before it neutralises.
Equipment-
For this test I will have to use the following equipment:
* 0.5 mole hydrochloric acid to neutralise the antacid tablet.
* Four types of antacid tablet for experimenting on (Rennies, Boots,
Settlers, and Bisodol).
* A burette to hold and measure the acid.
* A stand and clamp to hold the burette.
* Conical Flask to hold the antacid tablet and pour the acid into.
* A pestle and mortar to crush the antacid tablet in.

Using topical 5-animolevulinic acid or ALA before the blue light acne treatment is being considered more and more as this makes the skin more resistant to light, thus making the blue light therapy more effective in killing the bacteria on the skin which cause acne. This acid does have more side effects than the blue light therapy used alone. It could cause hair follicles to swell. The patients who are treated with ALA along with the blue light treatment are advised to use sunscreen with 50 spf to make the treatment effective and reduce the side effects.
Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
Whilst doing the experiment there are many things that will have to remain the same in order to keep the tests fair, these include amounts and measurements as well as concentration and size and shape of the magnesium e.g. long strands. The temperature how ever will be the main change in the experiment, this is the only factor to change in less problems occur where a change is not optional. For each temperature the test will be taken three times to make sure that the results are correct and as accurate as possible, an average will be taken to give a clear and single result. A diagram of the apparatus I intend on using and how it will be assembled; [IMAGE] Safety- To ensure that the investigation is safe I will make sure that all equipment it correctly assembled, and I am wearing the appropriate safety wear and that everybody around is either dressed correctly or far enough away.
As I do this experiment the thing I am going to be changing is the
and alcohol which I am using is on a brick under a tripod. On the
Normal water will not do because of the impurities in it. · Methyl Orange indicator - The colour of this indicates when the sodium hydroxide has been neutralised by the hydrochloric acid. · Conical Flask - This is used to react the aspirin tablets with the sodium hydroxide. It is more appropriate to use as the shape of it makes it less likely that any should spill out. · Burette - This is used to add the hydrochloric acid to the sodium hydroxide.
Over the last five years, I have been collecting makeup. Over these years, I have discovered all of the different types of makeup and the different uses for it. In this essay, I will be informing my audience of the benefits of different kinds of makeup as well as their uses.
In which document described in IEEE 829 would you find instructions for the steps to be taken for a test including set-up, logging, environment and measurement?
If you spent any time in a toy aisle this past holiday season, you would have noticed a subtle shift starting to occur in toys. The old standby toys are giving way to more modern app-enabled versions. Manufacturers are finding any way they can to update classic toys to engage with modern tablets. Barbie is enabled with cameras that play back via apps, Fisher Price play sets embed them for interactive play, and Lego building sets can be controlled by them. Unless manufacturers embrace and utilize tablets with their products, the tablet will take over the toy market.
At present, cosmetics are always used in daily life. When we talk about cosmetics, most people will think of the things that only use for make-up such as lipstick, eye-shadow, mascara, blusher etc. But in fact cosmetics are not only mean to the things that only use for make-up but also shampoo, lotion or sunscreen. According to the US Food and Drug Administration (FDA) explains “Articles intended to be rubbed, poured, sprinkled, or sprayed on, introduced into, or otherwise applied to the human body… for cleansing, beautifying, promoting attractiveness, or altering the appearance.” (2014) The reason why people use makeups have different ways such as some people use for more confidence, some people use for protect the sunlight, and some people use for maintain their skin. However, there are a lot of people still worry about using the cosmetics since they believe that cosmetics are contained the dangerous chemicals that damage their body so they afraid of using them and try to avoid to use them. Although many people will be concerned that applying cosmetics may destroy their health, in fact, many experts have been confirmed that the use of cosmetic is not harmful to the human’s body. Moreover, cosmetics are also useful for users.
Technology has made our lives more productive in many different ways. One of the greatest inventions is Apple’s products. It leads to an evolution of tablet devices. An iPad or iPhone can act as a textbook, laptop, navigation, camera, notebook, gaming devices and more. It combines all the other devices into one, which allows us to manage our time effectively.
Throughout history, Women has put their life and health at danger with many of their own homemade cosmetics. For example, in some cultures, women has used arsenic, mercury, lead, and even leeches to give themselves the pale presence assumed beautiful in the olden days. We have come a long way from the days of using dangerous toxics and mixtures that are deadly to enhance our appearance. Today’s multibillion dollar cosmetic industry must meet strict government rules about what it can and cannot include in the products and they must follow safe manufacturing guidelines. The most serious injury you’re likely to get from your cosmetics today is an irritation, a rash, or allergies ...
