Question:
What determines the pH level of sand?


Replies:
Patricia,

Sand, like all natural soils has various components. Although pure sand is mostly silica and would have a neutral pH of 7, natural sand has a healthy dose of salt and some organic matter. These natural "impurities" of sand would give it a different pH from neutral.
