Webexpressed as a power of 10 is known as the pH. By definition pH is equal to the negative logarithm of the hydrogen-ion concentration. pH = -log[H+] = log 1/[H+] The pH scale ranges from 0 to 14, with 7.0 being neutral. Solutions with a pH below 7.0 are acidic while solutions with a pH above 7.0 are basic (or alkaline). WebDec 24, 2024 · In contrast, bleach has a pH of 12 as it is quite basic. Numbers in the middle of the scale are neutral, such as water, with a pH of 7. One level of pH is a 10x difference. For example, when comparing pH 7 to pH 6, pH 6 is ten times more acidic than pH 7. Furthermore, pH 6 would be 100 times more acidic than pH 8.
