What is a water balance?

Water balance can be defined as two completely different concepts. The first type has to do with water ions. When water is in its purest form, it contains the same number of positive, negative and neutral ions. The water must be absolutely clean to be observed because any ingredients disturb and changes the nature of ions. The second type of water balance includes a small example of a water cycle. Those who observe the water that rotate to steam and condensation inside the container should notice that the water level remains basically constant.

In order to obtain water that contains an ion balance, science students must distill it using very clean tools. These tools should usually be thermally sterilized in the oven so that they do not have to dive into the water or wipe with a cloth. Water used to test water balance should be distilled before. Distillation of already distilled water should provide the cleanest form of water. Students can use this experiment to use solar energy or can use DEstilation unit with tubes and collection chamber. Either way, it must still be carefully cleaned before use.

After the water was distilled twice, it should be poured into a sterilized container. Students can use anemometer or wires from a simple electrical circuit to see if distillation has helped to achieve water balance. If the water contains a balanced number of ions, it should quite easily perform electricity. The anemometer should record at least 0.5 in electricity passing through water. Science students can also connect two wires to clips on the bulb holder and insert the other end of each wire into the water. If the water is balanced, the perimeter will complete and the bulb lights up.

When foreign objects are introduced - such as mud, chemicals or other fluids - the water disrupts the ion balance. Highly distilled water described above contains the same number of H _{3 O+, OH- and H 2 about neutral ions. The introduction of foreign objects usually increases the number of neutral ions by causing a combination of some positive and negative ions.}

The second type of water balance usually mimics the water cycle. In nature, the sun evaporates water from lakes, rivers and ocean to form steam in the air. When the air becomes heavy condensation, it falls back to the ground like a rain. The same concept can be observed inside a covered container filled with about a quarter of full water. If the container is heated, the water at the bottom of the container evaporates and travels to the top. Once there, it cools into condensation. When the condensation builds, it falls back to the bottom of the container. In these circumstances, water is equilibrium, because no matter how much water it seems in the container, it is always the same amount.
