Ph scale with substances
WebOn the PH scale, acid and alkaline are two opposite end. The strongest acids (lowest on the ph scale) are known for being corrosive and basically burning through everything. So what are the properties of alkaline substances? And why are the only “safe” ph levels neutral/in the middle of those two? Vote. 1. WebThe pH scale is used to classify substances as acids and bases. The scale goes from 0 to 14. Things that are acids have a pH number that is less than 7. The lower the number, the stronger the acid. Bases have pH values higher than 7. The higher the number, the stronger the base. An example of a
