Paragraph: There are some deposits of nitrates and phosphates in earth's crust. Nitrates are more soluble in water. Nitrates are difficult to reduce under the laboratory conditions but microbes do it easily. Ammonia forms large number of complexes with transition metal ions. Hybridisation easily explains the ease of sigma donation capability of NH ₃ and PH ₃ . Phosphine is a flammable gas and is prepared from white p

Options

  1. Aphosphates have no biological significance in humans
  2. Bbetween nitrates and phosphates, phosphates are less abundant in earth's crust
  3. Cbetween nitrates and phosphates, nitrates are less abundant in earth's crust
  4. Doxidation of nitrates is possible in soil

Correct answer

C. between nitrates and phosphates, nitrates are less abundant in earth's crust

Step-by-step solution

Due to greater solubility and nature to be prone to microbial action, nitrates are less abundant in earth's crust.
