WebAug 13, 2024 · The pH of pure water or any neutral solution is thus 7.00. Due to the somewhat less intuitive rules for dealing with significant figures in the context of logarithms, only the numbers ot the right of the decimal point in the pH value are the significant figures. Since \(1.0 \times 10^{-7}\) has two significant figures, the pH can be reported as ...
