WebThe pH scale is directly related to the OH- concentration while inversely related to the H+ concentration. A pH value increases as the OH- ion concentration increases, while the H+ ion concentration decreases with the increasing pH value. 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.

Webso at the end (last problem), the PH value for neutral (equal concentration of H+ and OH-) water @ 50°C is 6.64. I've always assumed that only PH=7 is neutral. Does the neutral PH value of everything depend on temperature? In other words, does the [H+]= [OH-] concentration equilibrium change depending on the temperature? Answer • Comment ( 2 … WebAug 9, 2024 · The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7. The pOH is convenient to use when finding the hydroxide ion concentration from a solution with a known pH. Example \(\PageIndex{1}\)
