Titrations in Modern Industrial Laboratories

Extracts from this document...


Quality Control for Pharmaceutical Products Producing pharmaceutical products ready for consumer is important because Quality assurance is the sum of all parameters concerning the preparation and control of a finished product. It is a wide term commonly used for the confirmation and validity of various ways and measurements adopted to obtain a high quality procedure for intended use with guaranteed performance. Biological quality control of pharmaceutical products becomes essential and to keep the risks of producing pharmaceutical products as minimum as possible as they are ultimately to be consumed by living organisms, in particular the humans. A standard solution is a solution whose concentration is known accurately. Its concentration is usually given in mol dm-3. When making up a standard solution it is important that the correct mass of substance is accurately measured. It is also important that all of this is successfully transferred to the volumetric flask used to make up the solution. ...read more.


In different industries the process is usually automated thereby eliminating human error, as the answers would be digital and not guessing, however for this there could also be the risk of systematic error, but this is a lot more quicker than the titrating by hand, where the accuracy is at most importance. Automated titration is also used in industry for titrating large amount of volumes. Also, in industry, different industries may also, measure the endpoint differently, as they may use a PH indicator, a potentiometer or a PH meter. However, you cannot always trust the concentration on the bottle, as the concentration should be one number, but then the concentration could be 0.1 out, and this could affect your results overall. This is why you should check the concentration of the iodine, so then the results are accurate. The winemaker industry are moving away from old manual titrations, colour indicators, time consuming aeration oxidation tests and dilution calculations to more accurate, more dependable and faster methods. ...read more.


For example, these may be the various fluids contained within naturally occurring well bore fluids. Thus, an operator may travel with portable titration equipment to a field location whereupon the operator can draw a fluid sample from a well bore or tank at the drilling site and place the sample solution in the source reservoir subject to flow by pump. Titration under control of digital computer may then examine successive portions of sample solution from source reservoir with respective reagents to identify, for example, phosphors, barium, calcium, chlorides, etc. Suitable program control of digital computer will enable such sequential fluid sample examination as the sample with successive reagents is flowed through delivery tube and the ultrasonic mixer to the mixing tube whereupon color detector provides indication output to the digital computer. In some cases where an indicator chemical is required in combination with the particular reagent, the indicator can be added directly into the solution in the reservoirs. ?? ?? ?? ??

    Determining the concentration of acid in a given solution

    5 star(s)

    If there was more sodium carbonate in the flask before I added my known mass, then the concentration would be higher than I calculated. This would mean that more acid would be needed to neutralise it, and I would think that the acid had a lower concentration than it actually did.

  2. Peer reviewed

    Deducing the quantity of acid in a solution

    5 star(s)

    Accuracy means the quality of nearness to the truth or the true value. That is why being accurate is the most important aim in this experiment. There could have been both precision and procedure errors that could have affected this aim.

First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention. Contact with eyes Redness. Pain. Safety goggles, or eye protection in combination with breathing protection if powder.

    is the overall order of the reaction (3) To find out the order of reaction of substrate A, experiments need to be conducted where the concentration of substrate A need to stay the same. By keeping the concentration the same of substrate A and getting enough results to plot a graph we can see what order of reaction it is.

  1. Dipoles and their importance

    The larger the atoms in a molecule, the higher the probability that an instantaneous dipole will exist as the electron cloud will be bigger and further from the nuclei so therefore the electrostatic attraction holding the electrons in place will be weaker and they would be more free to move,

  2. The Effects of Strong and Weak Acids on the Order of a Reaction.

    For First order graphs, the successive half lives are equal. This means that the time taken for the concentration of the reactants to be halved is constant. For Second order graphs, the successive half lives of the curve increase in size.
