POST-LAB QUESTIONS:1) Why are solutions standardized?2) Why was a back-titration needed for the antacid?3) What other indicators could have been used for the standardization of HCl and NaOH?4) What would be the consequence of competing equilibria, such as from other ingredients in the tablet, on your results? What if there were several pain relievers in the same tablet? How could the error from these interferences be minimized?5) Ethanol was used in the solutions to help dissolve the aspirin. Ethanol is slightly acidic and will react with NaOH. Describe a blank correction experiment, i.e., what experiment you might do to determine how much NaOH reacts with the ethanol in your solution. Once you have determined this, how would you use the results of a blank correction experiment in the data analysis?

Since you have asked multiple question, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.Titration is a method of qualitative chemical analysis which is used to determine the concentration of a given analyte in the mixture by adding an exactly known quantity of another substance to the measured sample and the analyte reacts with ot in a definite proportion. Standard solution is a solution that has exactly known and accurate concentration or amount of a particular substance. It is used in titrations to identify and determine the concentration of a substance whose concentration is unknown.The solutions are standardized in order to obtain reliable and transparent titration results. This can also help to rule out certain chemical species. Standardizing the solutions helps different systems and products work together seamlessly, reducing compatibility issues. This in turn can improve the efficiency of the analysis.

Will the calculated Molarity of NaOH be too high or too low or unaffected if the following happen: When you answer the question, consider how the situation affects the calculation of molarity of NaOH and moles NaOH, which is calculated from the mass of KHP. For each answer, you must supply a clear explanation for your answer. Often times, students will restate the facts rather than explaining why they chose the answer they chose. a) You add the weighed KHP to a flask containing a 60mL of water rather than 50 mL of water. Explain. Your answer must contain a well-thought-out and clearly written explanation. b) The buret is still wet with water on the inside when you add your NaOH solution. Explain c) The KHP is wet when you weigh it. Explain. d) You titrate past the equivalence point by 0.50mL Answer a-d
