Soil Analysis-Determination of pH of Soil

The visual explanation is Outstanding here. I just opened the inorganic chemistry analysis determination of pH of soil experiment. I just clicked the animation option and it leads me to the experimental video part.

 At first they showed me, the correct calibration of soil analyzing step by step with the electoral rod by checking the pH 4 and pH 7 and pH 9.2 buffering water which are in separate beakers. 

        Next they switch on the soil analyzing metre, they put a 20 grams soil into it and mix it with 40 ml water and check the pH of soil by use of soil analysis metre.

By this we can easily find out the pH level of soil.

Through this Visual explanation I have got real experience some sitting in my home.
