microteaching session I presented to my peers in a clinical placement regarding Nursing management of chest drains. I will define reflection; teaching‚ learning and the rationale for choosing this topic will be clearly outlined in this paper. The preparation‚ planning‚ implementation and evaluation will also be incorporated. This assignment will be structured using Gibbs (1988) reflective model cited in Modular Training Course‚ 2003 because of its simplicity. Analysis will permeate through each stage

has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the following are buffer systems? (a) KF/HF (b) KCl/HCl‚ c) Na2CO3/NaHCO3 (a) KF is a weak acid and F- is its conjugate base buffer solution (b) HCl is a strong acid not a buffer solution (c) CO32-

Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore

ion has donated/shared its electrons to the empty pi star orbitals of C atom. This has significant effect on C=O strength hence low energy absorption. Preparation of- Manganese(III) tris(acetylacetonate) Abstract In this experiment Manganese (III) tris (acetylacetonate) - [MnIII(acac)3] is prepared using manganese chloride‚ sodium acetate and acetylacetone‚ further analysis were done to find the percentage of manganese in complex. Introduction Manganese is a first row transition metal that

The pH of various mixtures and find the dissociation constant of acetic acid Chemistry (HL) Research Question: To determine the pH of various mixtures of sodium acetate and acetic acid in an aqueous solution and hence to find the dissociation constant of the acetic acid. Background: The mixture of sodium acetate and acetic acid in aqueous solution is a buffer solution. Buffer solutions are the solutions which resist a sudden change in the pH due to addition of small amounts of strong acid or base

Cobalt(II) Oxygen adduct complex Inorganic 461 lab 2-29-2012 Abstract This experiment uses Co(salen) as a model compound illustrating the uptake of oxygen in hemoglobin. SalenH2 was prepared as the intermediate‚ and reacted with hydrated cobalt to prepare Co(salen). Using Co(salen) the oxygen up-take was tested. The synthesis of SalenH2 produced 0.65 g. The percent yield of salenH2 was 116% on the filter paper and 105% after transferring salenH2 to a vial. The melting point of salenH2‚ was

buffer solution. One is capable of reacting with OH- and the other will react with H3O+ and they must not react with each other. Many buffers are prepared by combining a weak acid and its conjugate ( as in this experiment‚ acetic acid and sodium acetate) or a weak base and its conjugate (ammonia and ammonium chloride). In general‚ the pH range in which a buffer solution is effective
