Question

In electro-osmosis method, when direct current is applied to the electrodes, the soil water will _________

(a) travel from positive electrode to negative electrode

(b) travel from negative electrode to positive electrode

(c) move towards the centre between the electrodes

(d) not be affected by the current

I got this question by my school teacher while I was bunking the class.

I want to ask this question from Drainage and Dewatering in division Drainage and Dewatering of Geotechnical Engineering I

Answer 1

Right choice is (a) travel from positive electrode to negative electrode

For explanation I would say: When direct current is applied to the electrodes, the soil water will travel from positive electrode to negative electrode. The cathode is made in the form of a well point from where seeping water can be pumped out.
