Which of the Following Soil Minerals is Most Likely Leached

Question

Which of the following soil minerals is most likely leached away during a hard rain?
A)Na⁺
B)K⁺
C)Ca⁺⁺
D)NO₃⁻
E)H⁺

Accepted Answer

NO₃⁻ is a negatively charged ion and therefore not strongly attracted to the soil particles, making it more susceptible to being washed away during a hard rain. The other options are all positively charged ions and are more likely to be held tightly to the negatively charged soil particles.
