WebMar 24, 2024 · p H is a logarithmic function of [ H 3 O +]: (13.11.1) p H = − log [ H 3 O +] p H is usually (but not always) between 0 and 14. Knowing the dependence of p H on [ H 3 O +], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. WebJun 19, 2024 · pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

WebpH scale is based on neutral water, where [H +] = [OH –] = 10 -7 For a neutral solution pH = = – log [H +] = – log [10 -7] = +7 pH of strong acid decreases with a limit of 1 and pH of a base increases up to 14 Generally, acids and bases will have a pH between. But negative and greater than14 pH values are also possible. WebThe logarithmic scale of pH means that as pH increases, the H+ concentration will decrease by a power of 10. Thus at a pH of 0, H+ has a concentration of 1 M. At a pH of 7, this decreases to 0.0000001 M. At a pH of 14, there is only 0.00000000000001 M H+. ...

Logarithmic scales are linear scales in ‘x’ such as 1.0, 2.0, 3.0 etc, but they represent magnitude changes of 10, 100 and 1000 etc. Because natural phenomena span such a large range in energy, logarithmic scales are often used to represent

WebAug 21, 2024 · Logarithms are a concept that comes up over and over in introductory geoscience: radioactive decay, Richter magnitude, pH scale, etc. When each new topic is introduced, make sure to point out that they have seen this type of function before and should recognize it. WebOne way to start this problem is to use this equation, pH plus pOH is equal to 14.00. And we have the pOH equal to 4.75, so we can plug that into our equation. That gives us pH plus 4.75 is equal to 14.00. And solving for the pH, we get that the pH is equal to 9.25.
