It's 42 kHz which can be be achieved by either ultrasound or radiowaves or both but because you need pure water to split it at this frequency so it's kinda impractical-tho if you vibrate water at this frequency it makes standard electrolosys more efficient-several designs to do this exist in the literature. Best Answer.
QuÃ©bec is the largest province in Canada. Its territory represents 15.5 per cent of the surface area of Canada and totals more than 1.5 million km2.
