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.

WebJan 6, 2024 · The base is a substance that produces OH- ions in solution. If hydrogen ions H + outnumber hydroxide ions OH -, the solution is acidic. The pH scale ranges from 0 to 14. Pure water is neutral and has a pH value of 7. When pH values are below 7, they correspond to acids, while values above 7 correspond to bases. WebFeb 24, 2024 · The pH scale is a tool chemists have devised to measure how acidic (or alkaline, the opposite of "acidic") a solution is. It is used every day in countless applications, from checking whether the chlorine level in your hot tub is where it should be to allowing biochemists to figure out ideal conditions for reactions affected by acidity to occur.

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.

WebSep 9, 2024 · The pH scale is a familiar concept for students who study science.
