Complexometric Determination of Water Hardness Lab Report Introduction: In this lab the use of disodium salt of EDTA is used to determine the concentration of M^2+ metal ion impurities in hard water by chelometric titration. The indicator Eriochrome Black T will help detect when you EDTA has completely chelated the metal impurities. Chemical Principle: A complex ion consists of a metal ion with Lewis bases attached to it. These Bases form strong covalent bonds with the central complex ion in which

Data-collection in Qualitative Research This Chapter is about methods and techniques in data-collection during a qualitative research. We mentioned earlier that qualitative research is eclectic. That is‚ the choice of techniques is dependent on the needs of the research. Although this should be true for almost all social research‚ it is particularly so with qualitative research in that the appropriate method or techniques is often identified and adopted during the research. Qualitative research is also

(2014) define a qualitative research interview as “a scientific research process based on verbal communication aimed at gathering information in relation to a specific aim”. Qualitative research interviews allow for the collection of data on an individual’s thoughts‚ perceptions‚ feelings‚ sensations and attitudes on their disease and its treatment (Brédart et al.‚ 2014). Although the topic in the qualitative interview is controlled by the interviewer and the questions

EXPERIMENT NO. 5 COMMON ION EFFECT Lopez‚ Pauline G. HIJ-2‚ Group No. 5‚ Ms. Jervee M. Punzalan Ramales‚ Ayane Mark Q. September 15‚ 2014 I. ABSTRACT The common ion effect involves how the solubility of a salt changes when some ion that is common to both added substance and the salt in question is introduced. The presence of a common ion hinders the ionization of a weak acid or a weak base hence this is known as the common ion effect. Simply put‚ the effect

Exercise 14: Qualitative Anion Tests PURPOSE: The purpose of this experiment is to identify some commonly occurring anions & to study some of the reactions used for their identification. PROCEDURE: You must first determine to which of the three groups the various anions belong. Since no two people observe the same event in exactly the same way it is important to also conduct specific confirmation tests on the known samples of each anion. This information will help identify the anion

Determination of KHP – Acid - Base Titration For determining purity of unknown KHP‚ acid – base titration was used. Molarity of titrant in this case NaOH was standardized as 0.04958(±0.00011) M. Purity of unknown KHP was calculated as 35.88(±0.16) %. • Introduction Acid – base titration is typical method of determining unknown figures. Acid – base titration means that by using neutralization between acid and base. Abrupt changing of pH says whether procedure is done or not. pH indicators

For thousands of years‚ this question has puzzled philosophers‚ scientist and anyone who thinks about how they choose to act and live. Part of the complexity of the matter is related to the metaphysical nature of the subject which has a close affinity with the concept of GOD.

about the Nursing shortage. The abstract offers a clear overview of the study. The abstract states that the problem stems from the nursing shortage‚ and this is what causes stress and burnout. The abstract also states that the “study used a qualitative theory approach to examine the experiences of nurses and their particular concerns about caring for a dying patient” (Peterson‚ 2010). The purpose of the study is to examine the experiences of nurses and their concerns about caring for the dying
