1.Water can be decomposed into its elements by applying an external voltage. Hydrogen gas form sat one electrode and oxygen at the other, according to the following overall equation : 2H2O(l)→2H2(g) + O2(g)The hydrogen gas evolved by this reaction was collected in a water-filled tubeat 25 °C. The water levels were equalized to make the pressure of the trapped gas equal to the ambient pressure.However, the trapped gas is actually a mixture of hydrogen gas and water vapor. The partial...
