Question

Why is spring water pure enough for drinking but unsuitable for laboratory use?

Answer 1

Hint: Water collected from a natural spring is known as spring water. Unlike many other types of bottled water, which are filtered and processed to remove contaminants, water from a natural spring is said to have a beneficial quantity of minerals and is usually bottled right at the source.

Complete answer:
As spring water has been filtered through many layers of earth, it is devoid of suspended pollutants and germs (dangerous bacteria) and is safe to drink. Because spring water contains dissolved contaminants resulting from the nature of the soil surrounding the spring, it cannot be used in laboratories where distilled water free of impurities is required.
Unsolved impurities in spring water enter the water from the surrounding soil, and soil impurities (salts) vary by location. As a result, the flavour of water varies from place to place.
Water that has been heated into vapour and then condensed back into liquid in a separate container is known as distilled water. Impurities in the original water that do not boil below or near water's boiling point stay in the container. As a result, distilled water is pure water.

Note:
When washing items used in medical procedures such as dental check-ups or surgery, distilled water is essential. Instruments used in such treatments require special care. As a result, following washing, distilled water must be used to eliminate the detergent. Also, after being rinsed with distilled water, tools will not have any staining.
