| Hello everyone.Welcome to this tutorial on '''Conductivity of ionic solutions'''.

|-
|00:07
|In this tutorial we will learnt to:

* Measure Conductivity and

*Calculate the resistance of ionic solutions.

|-
|00:15
|Here I am using,
* '''ExpEYES''' version 3.1.0
* '''Ubuntu Linux OS''' version 14.04

|-
|00:23
|To follow this tutorial, you should be familiar with:

'''ExpEYES''' Junior interface.
If not, for relevant tutorials, please visit our website.

|-
|00:35
|Let's first define conductivity of a solution.

|-
|00:38
|'''Conductivity''' of a solution is a measure of its ability to conduct electricity.

|-
|00:44
|'''Conductivity''' of water is directly related to the concentration of ions dissolved in it.

|-
|00:51
|Now we will demonstrate conductivity of tap water.

|-
|00:56
|I will explain the circuit connections.'''A1''' is connected to '''SINE'''.

|-
|01:02
|Wires from '''SINE''' and '''A2''' are dipped in glass tumbler containing tap water.

|-
|01:08
|'''10K''' resistor is connected between '''A2''' and '''GND'''.This is the circuit diagram.

|-
|01:16
|Let's see the result on the '''Plot window'''.

|-
|01:20
|On the '''Plot window''', click on '''A1''' and drag to '''CH1'''.'''A1''' is assigned to '''CH1'''.

|-
|01:28
|Click on '''A2''', drag to '''CH2'''.
'''A2''' is assigned to '''CH2'''.

|-
|01:35
|Move the '''mSec/div''' slider to adjust the waves.Two sine waves are generated.

|-
|01:43
|Black trace is the original sine wave.Red trace is conductivity of tap water.

|-
|01:50
|Click on '''CH1''' and drag to '''FIT'''.Click on '''CH2''' and drag to '''FIT'''.

|-
|01:56
|Observe the voltage and frequency values on the right side of the window.Notice that voltage of tap water is very less compared to the input voltage.

|-
|02:08
|Right click on '''CH1''' to see voltages and Phase difference in degree.

|-
|02:15
|Now we will measure conductivity of copper sulphate solution.To make the solution one spatula of copper sulphate is dissolved in 100 ml of water.

|-
|02:27
|In the same connection, wires from '''SINE''' and '''A2''' are dipped in copper sulphate solution.

|-
|02:34
|On the '''Plot window''' we can see the conductivity curve.

|-
|02:38
|Red trace is conductivity of copper sulphate solution.

|-
|02:42
|Increased conductivity of is due to copper and sulphate ions present in the solution.

|-
|02:48
|Observe the voltage and frequency values on the right.

|-
|02:52
|Right click on '''CH1''' to see voltages and '''Phase difference''' values.

|-
|02:59
|Now we will measure conductivity of dilute sulphuric acid solution.A few drops of dilute sulphuric acid are added to water.

|-
|03:09
|Wires are dipped in sulphuric acid solution.Let's see the result on the Plot window.

|-
|03:17
|Observe that black and red traces are almost coinciding with each other.

|-
|03:23
|Conductivity of tap water has increased: on adding a few drops of dilute sulphuric acid.

|-
|03:30
|Observe the voltage and frequency values on the right.

|-
|03:34
|Right click on '''CH1''' to see voltages and '''Phase difference''' in degree.

|-
|03:41
|We will measure conductivity of dilute Potassium hydroxide solution.A few drops of dilute Potassium hydroxide solution are added to tap water.

|-
|03:52
|We can see that black and red traces are almost coinciding with each other.

|-
|03:58
|Notice the increased conductivity of:
tap water on adding a few drops of Potassium hydroxide solution.

|-
|04:05
|Observe the voltage and frequency values on the right side of the window.

|-
|04:11
|Right click on '''CH1''' to see voltages and Phase difference in degree.

|-
|04:18
|Using the voltage values we have calculated the resistance of ionic solutions and tabulated the results.

|-
|04:27
|Resistance value for tap water is '''7.7 KOhm'''
Resistance value for:
copper sulphate solution is '''1.2 KOhm'''

|-
|04:38
| sulphuric acid solution is '''0.17 KOhm''' and * potassium hydroxide solution is '''0.14 KOhm'''.
Notice that resistance values decreased with the increase in ionic concentration.

|-
|04:55
||Let's summarize.

|-
|04:57
