- pH - Wikipedia
It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions Acidic solutions (solutions with higher concentrations of hydrogen (H +) cations) are measured to have lower pH values than basic or alkaline solutions The pH scale is logarithmic and inversely indicates the activity of hydrogen cations in the solution
- Logarithmic scale - Wikipedia
A base-10 log scale is used for the Y-axis of the bottom left graph, and the Y-axis ranges from 0 1 to 1000 The top right graph uses a log-10 scale for just the X-axis, and the bottom right graph uses a log-10 scale for both the X axis and the Y-axis Presentation of data on a logarithmic scale can be helpful when the data:
- Acid dissociation constant - Wikipedia
At half-neutralization the ratio [A −] [HA] = 1; since log(1) = 0, the pH at half-neutralization is numerically equal to pK a Conversely, when pH = pK a, the concentration of HA is equal to the concentration of A − The buffer region extends over the approximate range pK a ± 2 Buffering is weak outside the range pK a ± 1
- Logarithm - Wikipedia
The non-sliding logarithmic scale, The activity of hydronium ions in neutral water is 10 −7 mol·L −1, hence a pH of 7 Vinegar typically has a pH of about 3
- S. P. L. Sørensen - Wikipedia
From 1901 to 1938, Sørensen was head of the prestigious Carlsberg Laboratory, Copenhagen [2] While working at the Carlsberg Laboratory he studied the effect of ion concentration on proteins [3] and, because the concentration of hydrogen ions was particularly important, he introduced the pH-scale as a simple way of expressing it in 1909 [4]
- pH indicator - Wikipedia
A pH indicator is a halochromic chemical compound added in pOH = pK b + log 10 they are usually destroyed at the extreme ends of the pH scale due to undesired
