What is the pH range for alkaline soil? Is it considered sweet or sour?
A
sweet
B
8-14
C
sour
D
6-0
Explanation: 

Detailed explanation-1: -Soils can be classified according to their pH value: 6.5 to 7.5-neutral. over 7.5-alkaline. less than 6.5-acidic, and soils with pH less than 5.5 are considered strongly acidic.

Detailed explanation-2: -The pH scale ranges from 0 to 14, with 7 being neutral. A pH value below 7 indicates the soil is acidic, while values above 7 are alkaline. Each unit change in the pH scale is a 10-fold difference in acidity or alkalinity. For example, soil with a pH of 8 is ten times more alkaline than soil with a pH of 7.

Detailed explanation-3: -A sweet soil is alkaline with a pH of 7.5 or higher. A sour soil is acid, with a pH of 6.5 or lower. The pH scale runs from 0.0, the most acidic, to 14.0, the most alkaline.
