# Variation of conductance with temperature in electrolytes

To investigate the effect of variation in temperature on the permeability of cell membranes using fresh beetroot aims in this investigation, you will subject fresh, washed beetroot discs to different temperatures to investigate the effect of temperature on the permeability of the plasma membrane. Conductance the reciprocal of the resistance is called conductance it is denoted by c c=1/r conductors allows electric current to pass through them examples are metals, aqueous solution of. The conductance of concentrated electrolyte solutions and its temperature dependence are of technological interest, eg high energy and low temperature batteries, electrolysis. The variation of molar conductance with concentration can be explained on the basis of conducting ability of ions for weak and strong electrolytes for weak electrolytes the variation of with dilution can be explained on the bases of number of ions in solution.

Conductivity when voltage is applied to the electrodes immersed into an electrolyte solution, ions of electrolyte move, and thus, electric current flows through the electrolytic solution the electrolytic solution and the metal conductors exhibit resistance to the passage of the current both of which obey ohm's law. To find the variation of conductance with temperature in electrolytes apparatus glass beaker, cuso 4 solution, cu electrodes, znso 4 solution, zn electrodes, rheostat, battery eliminator, water, burner, thermometer, flask, ammeter, voltmeter.

Variations of molar conductivity with concentration specific conductivity or conductivity of an electrolytic solution at any given concentration is the conductance of unit volume of solution kept between two platinum electrodes with unit area of cross section and at a distance of unit length. O o result the relevant graph shows that the 1 / resistance of an electrolyte increases at a steady rate as the temperature increases conclusion on heating a solution, it is known that viscosity gradually decreases, with decrease in viscosity, the speed and movement of the ions increases.

## Variation of conductance with temperature in electrolytes

The solution should be kept undisturbed throughout the experiment the conductance of the electrolyte increases with increases in temperature bibliography chemistry (part i) - textbook for class xii it is known that viscosity gradually decreases. Recent theoretical extensions of the onsager conductance equation are tested by comparison with conductance data for sodium chloride, potassium chloride, potassium bromide, potassium iodide and.

• The temperature coefficient is typically +3×10 −3 k −1 to +6×10 −3 k −1 for metals near room temperature it is usually negative for semiconductors and insulators, with highly variable magnitude.
• Strong electrolytes such as kno 3 have a high degree of dissociation and hence their solutions have the high concentration of ions and so they are good electrolytic conductance temperature it has been seen that higher temperature enhances the solubility of electrolytes and hence the concentration of ions which results in an increased.
