Question

The purest form of water that is considered to be ___________ .
A.) Tap water
B.) Water from wells
C.) Bore water
D.) Rain water

Answer 1

Hint: In order to deal with this question first we will define the term purest water further according to its properties we will see in which form we will get it.

Complete step-by-step answer:

Clean water, also known as filtered water, is source water from which all impurities have been extracted. Pure water is the most popular source of purified water. Carbon filtration, micro-porous filtration, and ultraviolet oxidation will purify the fresh water. Some sites use a mix of processes of purification.
Pure water in chemistry, on the other hand, means pure , the organic water solution without any dissolved salts or gasses. However clean drinking water contains traces of minerals such as salt, magnesium etc. as per WHO requirements and traces of carbonates and dissolved gases such as oxygen.
Rain water is the purest source of natural water. In the case of the sun, the rain water comes straight from the condensation of vapor. The water evaporates from ponds, lakes, and rivers. During the vaporization cycle all the impurities are eliminated, and then water in the form of rain falls straight into the soil.
Hence, the purest form of water that is considered to be rain.
So, the correct answer is option D.

Note- Water purification is the process of removing unnecessary chemical substances, biological contaminants, suspended solids and water glasses. The intention is to generate water that is suitable for different purposes. Such requirements commonly provide minimal and maximum contaminant concentrations, depending on the expected application of the water. The four chlorination, distillation, heating, and filtration methods for water purification are as follows. With chlorination, you're going to get basically what's done in ponds to kill and remove bacteria.
