Difference between pH of 4 and pH of 10?
The pH scale ranges from 0-14 pH. A substance that has a pH of 7 is considered to be "neutral," like pure water. A substance that has a pH less than 7 is said to be acidic, and a substance that has a pH greater than 7 is said to be basic. Therefore, the difference between those two pH levels is that the 4 pH substance is more acidic and the 10 pH substance is more basic. The more basic or acidic, the more caustic and/or corrosive the substance will be.
