Ph in mol/l
WebbMethod 1. Use properties of the log scale. Recall that \text {pH} pH scale is a negative logarithmic scale. Therefore, if the concentration of \text {H}^+ H+ decreases by a single … WebbThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. Image modified from " Water: Figure 7 ," by OpenStax College, Biology, CC BY 4.0.
