Question

The daffodil plants grow best in a soil having a pH range of 6.0 to 6.5. If the soil in a garden has a pH of 4.5, which substance needs to be added to the soil in order to grow daffodils?
(a) salt
(b) lime
(c) sand
(d) compost

Answer 1

(b) lime(calcium hydroxide) should be added as to lessen the acidic contain in the soil

Answer 2

Answer:

B) Lime

Explanation:

It is given that the pH of the soil is 4.5, which means it is acidic. The daffodil plants grow best in soil having a pH range of 6.0 to 6.5 ( that is almost neutral). In order to neutralize the soil, we need to add a base.

Here,

1. Salt has a pH of 7, so it cannot be used.
2. Pure sand is mostly made from silica, a substance with a neutral pH of 7 (neutral).
3. Compost has a pH of generally 6 to 7.5 (that is neutral).
4. Lime is a strong base and hence can be used for neutralizing the soil.

Therefore, Lime will be the correct answer.
