of ointment base. The types of ointment bases used as vehicles for drugs are selected or designed for optimum delivery of the drugs and also to contribute emolliency or other quasi-medicinal qualities. Ointments properties vary since they are designed for specific uses‚ ease of application or extent of application. The purpose of the lab was to learn the difference between different types of ointment bases. In this experiment‚ we learned how to measure the ability of each ointment base to incorporate

Lab Partner: Keren Appiahene Mussie Gide 10 September 2016 Experiment 2: Acid- Base Extraction Separation of an Organic Acid‚ a Base and a Neutral Compound Introduction: The extraction technique is often used in the organic lab to separate organic compounds from mixtures. One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into account when

Acid-Base Strengths of Organic Compounds By: Chris Frankmore Due Date: February 15‚ 2011 Resonance Benzenesulfonic Acid Benzoic Acid Benzyl Alcohol Benzylamine P-Cresol P-Toluidine Acid/Base | Structure | pH | Why It is a strong/weak acid/base | Benzenesulfonic Acid | | 1 | This is a strong acid because it has a pH of 1. Another reason why this is a strong acid is that its conjugate base has strong resonance stabilization

Equilibrium and Acid Base Test Review: May 2012 Things to know: 1. Explain DYNAMIC EQUILIBRIUM. Why does a reaction at equilibrium look like it is NOT reacting? 2. Are all reactions equilibrium reactions? What assumptions do we make when we say that a reaction does NOT take place or that it is UNIDIRECTIONAL and goes 100% to completion 3. Be able to sketch a graph of the following (assuming that you start with all reactants and no products) : a. A reaction that really doesn’t do anything

consistency. Consistency requires minimal temperature sensitivity. For those who anticipate shooting in different climate settings‚ single-base propellants (also known as nitrocellulose) will have less performance variation with temperature fluctuation when compared to double-base powders. Hodgdon and Vihtavuori 100 series are great examples of single-base powders.

ACID / BASE BUFFER SYSTEMS Abstract A buffer solution is a solution that contains both an acid and a salt containing the conjugate base / acid in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment a selection of buffer solutions (Bicarbonate/carbonic acid)‚ Lake water and distilled water were obtained to compare their buffering behaviours when mixed both with an acid and a base. The results showed buffering capacities for
