the bubble generation depends on current and pressure .Electrolysis of pure water requires excess energy in the form of overpotential to overcome various activation barriers. Without the excess energy the electrolysis of pure water occurs very slowly or not at all.
The net reaction can be summarized by the equation
2H2 O+electricity→2H2 →+O2 →
It must be borne in mind that the equation only shows what products are formed; it does not suggest a mechanism, which is more complex than suggested by this simple equation alone. For example, if NaCl is used in dilute, non-concentrated levels as an electrolyte in an aqueous solution subjected to electrolysis, it is known that both chlorine gas and oxygen can be generated at the anode while the hydrogen is being formed at the cathode. It is also known that if the aqueous sodium chloride solution is made very dilute, then little chlorine is formed at the anode in addition to the oxygen formed during electrolysis. Suffice it to say that it is an understood principle of basic chemistry, that depending upon the concentration and type of salt constituents present in an aqueous solution, formation of another type of gas, viz. chlorine, is possible in addition to the oxygen and hydrogen formed during electrolysis of water. mayb a problem ??
bubble generation
neutral bouyancy
Is it lyk wen the depth sensor is switched on the current passes through the electrode and bubblesd are produced?
LikeLike
no the depth sensor should switch on the switch when it reaches the correct depth .
LikeLike
after that they produce bubbles?
LikeLike
bubble production is by water electrolysis. current passes between the two electrodes , decomposing water to hydrogen and oxygen gas . http://en.wikipedia.org/wiki/Electrolysis_of_water .
