WebpH is a logarithmic scale. A solution that has a pH of 1.0 has 10 times the [H +] as a solution with a pH of 2.0, which in turn has 10 times the [H +] as a solution with a pH of 3.0 and so forth. Using the definition of pH, it is also possible to calculate [H +] (and [OH − ]) from pH and vice versa. The general formula for determining [H ... WebYes if [HCl] = 1M then the pH = 0. Negative pHs indicate an acidic solution with a [H₃O⁺] > 1M — you can just plug the values in to the equation to find out an exact answer for any value. I also recommend reading this short article: WebMar 6, 2012 · When the pH is above 7.0, the water is alkaline, or basic (there are more hydroxide ions than hydrogen ions). Since the scale is logarithmic, a drop in the pH by 1.0 unit is equivalent to a 10-fold increase in acidity. So, a water sample with a pH of 5.0 is 10 times as acidic as one with a pH of 6.0, and pH 4.0 is 100 times as acidic as pH 6.0. list of managers by wins
