Electrolysis of water is carried out by a current in which silvering of a plate having an area of S = 25 cm2 is carried out at a speed of v = 0.05 mm/s. Find the volume Vb of hydrogen released within an hour if the process occurs at a pressure p = 1.05 105 Pa and a temperature t = 41 °C. Electrochemical equivalent of silver Kс = 1.118·10-6 kg/C, hydrogen - Kв = 1.04·10-8 kg/C. The density of silver is pc = 10.5·103 kg/m3, of hydrogen (under normal conditions) - p0v = 0.09 kg/m3.
