PRACTICAL 2: Preparation of sodium hexanitrocobaltate (III) Date: 12 March 2014 INTRODUCTION Sodium hexanitrocobaltate (III) is a coordination complex which has the formula Na3[Co(NO2)6]. This compound is yellow in colour. It consists of a central Co3+ ion surrounded by six nitro ligands [1]. This compound is used as a qualitative test for potassium and ammonium ions (so long as certain other cations are not present) [1]. Potassium and ammonium are insoluble in water‚ while sodium is [1]. Hence‚ the

Title: Reaction of Iodoethane with Sodium Saccharin- Ambient Nucleophile Dates Performed: February 21 + 28‚ 2013 Date Submitted: March 14‚ 2013 Abstract: The product ratio of N-ethylsaccharin to O-ethylsaccharin that occurred due to alkylation with iodoethane at 80 oC was determined to be 81.5% to 18.5%‚ respectively‚ based on an analysis of the 1H NMR spectrum that was collected. The melting point range of 87.8-94.7 oC also indicated that the mixture was largely composed of N-ethylsaccharin

The third part Section C 5-25% of sodium chloride was prepared by the instructor. For each percent concentration of sodium chloride a 25 mL was prepared. Weighing the graduated cylinder before and after the sodium chloride was transferred the density were calculation. Pre- Laboratory Questions: 1.

Standardization versus Adaptation in International Marketing Introduction The most challenging decision that a company may face in internationalization is the degree of standardization or adaptation in its operations. The question of standardization or adaptation affects all avenues of a business’ operations‚ such as R&D‚ finance‚ production‚ organizational structure‚ procurement‚ and the marketing mix. Whether a company chooses to standardize or adapt its operations depends on its attitudes

Results and discussion: I. a. How would you compare that relative reactivity of Na and k -Sodium and potassium react somewhat similar when reacting with water however they are slightly different. Sodium moves because of the hydrogen coming off of it and has a low melting point while potassium’s reaction is faster and enough heat is produced to set light to the hydrogen coming off of it. Each leaves a pink color hue in the water. Discuss the similarities and differences in the behavior of the metals

Just in time is a strategy used by companies to improve efficiency and decreasing waste by receiving goods only when necessary which results in reduced inventory costs and to employ this strategy‚ a company must have the ability to accurately forecast demand. Benefits of using this strategy include cost reduction‚ delivery improvement‚ quality improvement‚ performance increases and increased innovation. Waste is eliminated through minimizing over production‚ reduced transportation‚ over processing

Standardization versus Adaptation There has been much debate over implementing a standardization strategy versus an adaptation approach across international markets. There are numerous factors to consider‚ along with pros and cons of both marketing plans. While standardization is equated with brand consistency‚ lower advertising costs‚ and overall synergy‚ adaptation is often required to address cultural differences for more effective communication and proves that cutting costs does not always

Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change‚ effervescence (bubbles)‚ when light or heat given off‚ and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning)‚ synthesis‚ decomposition‚ neutralization‚ single replacement and double replacement. A combustion reaction is a reaction with oxygen‚ and
