Abstract

We set up the experiment and prepared four electrolytes, each containing 0.10, 0.20, 0.30, and 0.40 g of sodium hydroxide in 400 ml. The experiment was conducted at 5, 10, 15, 20, 25, and 30 V from each of the four different electrolyte concentrations. For each sample, the commutative hydrogen production is notated/measured up to 20 ml, and the time for 20 ml hydrogen production is noted. The results show that at 5 V, the time required to produce 20 ml of hydrogen is longer, whereas at 30 V, the time required is shorter, regardless of concentration. Furthermore, when considering voltage, the time required to produce 20 ml of hydrogen from 0.40 g of electrolyte takes less time than 0.10 g.
