प्रश्न
Answer the following questions in short:
Why is spring water pure enough for drinking but unsuitable for laboratory use?
उत्तर
Springwater is free from suspended impurities and germs (harmful bacteria)as water has been filtered through different layers of soil and is fit for drinking. Springwater contains dissolved impurities due to the nature of the soil surrounding the spring and cannot be used for laboratory purposes, where distilled water free from impurities is needed.
