Question
I need help writting a description in which I woulddescribe and understand the titration of a solution of HCl using asolution of standardized NaOH as the titrant by using questionsbelow as a guideline. It's supposed to be around 325 words. Concisedescriptions are appreciated, thank you, thank you!
i. What is a titration? An analyte? A titrant?
ii. What glassware is needed to perform a titration?
iii. What is a standardization? Why would one need to make astandard solution?
iv. What is the equivalence point? What methods can be used todetermine the equivalence point?
v. How do you prepare a standard solution?
vi. What is an indicator? What is it's role in a titration?
vii. What is the laboratory method used to titrate an unknownstrong acid solution with a standardized strong base solution?
viii. What data should be collected during your titration in orderto calculate the concentration of HCl?
viiii. How do you calculate the molarity/concentration of theunknown HCl solution?

Explanation / Answer
1) The titration is a common laboratory method ofquantitaive chemical analysis that is used to determine theconcetration of unknon reactant.Because volume measurements play akey role in titration, it is also known as "volumetricanalysis".A reagent called the titrant or titrator, of a knownconcentration and volume is used to react with asolution of the analyte. whose concentration is notknown. 2) the glassware used in titration which is not react withanalyte or reagent in solution. It will used to shows clearlycolour change at eqivalence point. quantitavely mesaured standardglassware shall be used because we are doing quantitaiveanalysis. 3) Standardization orstandardisation is a process of developing andagreeing upon technical standards. . A standard is a document thatestablishes uniform engineering or technical specifications,criteria, methods, processes, or practicesSome standards aremandatory while others are voluntary. Voluntary standards areavailable if one chooses to use them. Some are de factrostandards, meaning a norm or requirement which has aninformal but dominant status. Some standards are dejure meaning formal legal requirements. Formal standardorganisations, such as the international standards forstandardization (ISO) or , are independent of themanufacturers of the goods for which they publish standards. 4) The equivalence point,or stoiciometric point, of a chemical reaction occurs during achemical titration when the amount of titrant added isequivalent, or equal, to the amount of analyte present in thesample. In some cases there are multiple equivalence points whichare multiples of the first equivalent point, such as in thetitration of a diprotic acid. A graph of the titration curveexhibits an inflection point at the equivalence point. A strikingfact about equivalence is that in a reaction the equivalence of thereactants as well as products is conserved. methods todetermine equivalence point are pH indicator, pH meter,potentiometer, conductivity method, spectroscopy method,etc.. 5)To standardize a solution of acid you simply titrate itagainst a solution of alkali of known concentration. Once you havecalculated this you can use it in turn as a standard solution, tofind the concentration of a solution of alkali. 6) A indicator is a halochromicchemical compound that is added in small amounts to a solution.it's role in titration are to find equivalence point by colorchange or potential change etc.. 7) the laboratary methos used to find unknown strong acidsolution with a strong base solution by Acid- Base titrations. thisis the best method . In this we find end pint by colorchange. 8) the data collected to find conc. of HCl sol are to knowbase vol and its concentraion, and end point
