multiple choice questions on conductivity
What is the specific conductance of a 0.1 M KCl solution?
The specific conductance of a 0.1 M KCl solution at 23 °C ° C is 0.012 Ω−1cm−1 Ω - 1 cm - 1. was found to be 55 Ω Ω. The cell constant will be: The k = k = 4.95 4. 95 × × 10−5S 10 - 5 S cm−1 c m - 1 for a 0.00099 M solution.
What is the purpose of the conductivity guide?
The main goal of this conductivity guide is to disseminate knowledge and understanding of this analytical technique, which will lead to more accurate and reliable results. This guide provides all the important basics that are necessary for a good understanding of conductivity measurement.
Which two parameters are commonly derived from the measurement of conductivity?
Two parameters which are commonly derived from the measurement of conductivity are TDS and salinity. TDS – or Total Dissolved Solids – is a measurement of the concentration of solids dissolved in the water, like inorganic salts or organic matter.
How to test the conductivity of a material?
An electric current produces a magnetic field. You can take advantage of this fact to make a simple apparatus to test the electrical conductivity of various materials, including both solids and liquids. The detector consists of a coil of wire, with a magnetic compass inside it. You connect one end of the coil to a D-cell battery.
