The results show that increasing the DC voltage will result in a faster release of gasses from the chemical reaction in the electrolyte. However, increasing the amount of salt in the electrolyte does not change the rate of gas released from the electrolysis process.
|Salt amount in electrolyte (in mg)||20||40||60||80|
|Time measured (in minutes)||14.4||14.3||14.3||14.4|
|Voltage applied (V dc)||1.5||3||4.5||6|
|Time measured (in minutes)||14.2||11.6||7.5||4.8|
Use only batteries. Do not connect the wires to a mains supply.
