Lab report: electrical conductance

Introduction

Electrical conductance is the property of an electrical conductor that determines how fast it contacts – how easily current flows through it (Shaw, 1911, p. 281). When a potential difference is applied across various types of conductors, current flows through the conductors at different rates. The rate at which the current flows through a particular conductor for a particular potential difference is dependent on the specific property of the conductor, referred to as electrical conductance. Conductance determines how well current flows through a particular conductor. Conductance is the inverse (reciprocal) of the property of the conductor ...

Introduction:

Nanobiotechnology serves as an imperative technique in the development of clean, nontoxic, and eco-friendly procedures for the synthesis and congregation of metal NPs having the intrinsic ability to reduce metals by specific metabolic pathways. Silver nanoparticles are particularly interesting nanoscale systems due to the ease with which they can be synthesised and modified chemically. Synthesis of silver nanoparticles has been widely researched due to their interesting size and shape-dependent properties [26]. These novel properties can be tailored by controlling their size, shape, composition, structure and crystallinity. Due to their size features and advantages over available anti-microbial properties, chemical imaging ...

The objective of this experiment was to prepare Beer-Lambert calibration curves for different forms of nitrogen and to determine the concentration of nitrate, nitrite, and ammonia ions in different water samples from the Biscayne Bay.

Introduction

Nitrogen is the most abundant element in the Earth atmosphere. In is not surprising that it is one of the most crucial elements not only to human life but all life on our planet. The chemistry of nitrogen is rather diverse because it can exist in different oxidation levels – from +3 to -5. Due to its large impact on the biosphere, the circulation of ...

Introduction The purpose of this lab was to find the amount and percentage of nickel present in an unknown compound using the "mole method." The unknown nickel compound was dissolved in water and treated with dimethylglyoxime and ammonia solutions to obtain the precipitate of known chemical composition (bis(dimethylglyoximo)nickel(II)), which then was weighed and using this data the amount and percentage of nickel in the initial compound were found. The insoluble Ni(DMG)2 complex is formed in two steps. First, the dimethylglyoxime reacts with hydroxide ion formed through the ammonia hydrolysis to produce dimethylglyoximate anion: C4H8N2O2( ...
