Question

iii) __________ soil has PH 7.​

Answer 1

Answer:

Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases the soil pH decreases thus becoming more acidic.

Answer 2

Answer:

neutral soil has PH7

Explanation:

Soil pH may vary from time and place.

As we know that neutral pH is the most

important for the growth of plants. If

Sodium increases in the soil pH than the

elements like magnesium, copper, etc.

are deficient in such soil.

On the other hand, acidic soil contains a

large amount of nitrogen but essentially

sodium and potassium are absent. The

pH generally depends on the rock from

which they are formed.
