TASK 4A
Explain why it is important when producing pharmaceutical products ready for consumers to prepare standard solutions and to carry out titrations accurately in a quality control laboratory.

D1

Standard solution
First of all a standard solution is a solution with the accurately known concentration. The unit of concentration is mol dm–3. [4]If we didn’t have standard solutions, we would be calculating information which is wrong of the solutions used for pH, absorbance, etc. if we didn’t have standard solution we wouldn’t know the accurate concentration of a product. Standard solutions have to go through many tests to make sure that they are accurate enough before they are able to be used in the products.
When making a standard solution anywhere even if it is in a lab or an industry it is important that you have the right type of PPE equipment (personal protective equipment). You will need a lab coat and goggles disposal gloves can also be used but they are not really as necessary as the other two. The first step in making a standard solution in a lab is by putting the weighing boat on a weighting scale and pressing the tare button which will set it to zero. This is done so that when you’re measuring the substance in this case sodium carbonate the beakers mass will not be calculated along with the substance so that you can get the accurate value. After you finish that it is important that when you are putting your substance into the weighing boat that you take it off the weighing boat because sodium carbonate is powder and it is very easy for powder to fall and if it falls while you were putting it into your beaker while it was on the weighting in scale it could change your results and you would have to start again. After you have carefully weighed up the amount of the required substance transfer it into a beaker and them use distilled water to rinse the weighing boat as some particle could have been left inside and add that into the beaker as well. After

    The Experiment and Observation: Weigh out your 1.0g of CaCl2-2H20 and put it into the 100mL beaker, add your 25mL of distilled water and stir to form the calcium chloride solution. Next, use stoichiometry to determine how much Na2CO3 and put it into a small paper cup. Then add the 25mL of distilled water to make the sodium carbonate solution. Mix the two solutions in the beaker and a precipitate of calcium carbonate will form instantly. Next, set up your filtration assembly. After the filtration assembly is ready, swirl the contents of the beaker to dislodge any precipitate from the sides. Then, pour the content of the beaker into the filter paper-lined funnel carefully. Afterwards you will need to measure out 2 to 5mL of distilled water into a graduated cylinder. Pour it down the sides of the beaker, swirl, and pour into the filter paper-lined funnel. Once all the liquid has drained from the funnel, lay the filter paper containing the precipitate on folded layers of paper towels and set it somewhere to air-dry. Once the filter paper and the precipitated calcium carbonate are completely dry, weigh them, subtract the original weight of the empty filter paper, and record the net weight of the calcium carbonate. That is your actual yield of calcium carbonate. Then, you can calculate the percent yield, using your theoretical yield and actual yield. Be sure to clean up properly, rinse any remaining chemicals down the sink and throw paper cups and towels in the garbage. Clean and dry all equipment you used. The following results will be observed:…

    First the student will take the weight of a clean dry beaker and record the data. Next ass .15g of the first unknown substance. From there, the student will add 50ml of water to the beaker then dissolve the .15g of the first unknown substance into the water. Once the substance has dissolved, the student will add 10 drops of bromocresol (indicator) into the beaker. After the student will fill the buret all the way up with HCl. Once that is done, begin titration. The HCl should be added into the beaker until the indicator turns green. After it turns green the student will then place it on a hot plate and heat it till the CO2 evaporates and it turns blue again. After that let it cool. Once the substance is cooled. The student will then titrate once more till it turns yellow. The yellow color indicates that the substance has stabilized. Once the substance is fully titrated, the student will place the beaker back on to the hot plate and let all of the water evaporate out of the beaker till there is only the salt (unknown substance) left. Lastly, the student will then measure the weight of the beaker with the salt in it and record the data. Once the data has been obtained the student will subtract the weight of the beaker from the weight of the salt. That calculation will then be used to find the…
