Quan Chapter 15: Redox Titrations 1. (A) Which of the following is true of a redox titration? (i) Since the redox reaction is spontaneous‚ the equilibrium constant does not have to be large for an effective titration. (ii) The titration effectiveness is increased when the two half-reaction potentials are far apart. (iii) Without an indicator the equivalence point cannot be detected. (iv) For an effective redox titration‚ the reducing agent must always be in the buret. (v) The equivalence

What is acceptance sampling? Discuss the concept of OC curve. Statistical Quality Control (SQC) is the set of statistical tools used by quality professionals. Acceptance sampling is a part of SQC. It is the process of randomly inspecting a sample of goods and deciding whether to accept the entire lot based on the results. This determines whether a batch of goods should be accepted or rejected. This is helpful in measuring and evaluating the quality of products or services. However‚ statistical

Initial post Comparing Qualitative and Quantitative Approaches Researchers often times are faced with the decision of choosing a methodology of research; either Quantitative or Qualitative that they think best fits their study and objectives. This choice is guarded by the topic of study‚ the advantages and disadvantages‚ and the strengths and weaknesses of using either one or the other type of the methodologies. Researchers are sometimes using Quantitative and Qualitative research methodologies interchangeably

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants
