A log-log scale is a set of axes where each axis is logarithmic in scale.
pH is a logarithmic scale; because of the way calculus and maths works, graphing such a scale against a log results in a straight line.
Whenever the data covers a very large range of values a log scale if very useful. Earthquakes and hearing are common examples.
No. The log of a quotient is the log of a denominator subtracted from the log of the numerator.

The anti-log of what ??? If log(12) = 1.07918, then antilog(1.07918) = 12 Did you want the anti-log of 12 ? That's 1,000,000,000,000.
It is called the magnitude scale. It is a log scale.
Many scales such as sound and PH are log scales. The scale used to measure earthquakes is also a log scale. Whenever the data has a very wide range, a log scale might help.
One axis (usually the vertical axis) is on a log scale, the other is a linear scale.
Yes. The pH scale is an inverse log scale of the [H].
pH is a logarithmic scale; because of the way calculus and maths works, graphing such a scale against a log results in a straight line.
The Doyle Log Scale, developed around 1825, is based on a mathematical formula and is widely used throughout the southern United States. This rule allows for a saw kerf of 5/16 inch (most circular mills). Because of this, the Doyle Rule is somewhat inconsistent; it underestimates small logs and overestimates large logs. To use a Doyle Log Scale measure the diameter of the log (not including the bark) and the length. Then using the Doyle scale you can calculate the board foot content of a log.
The pH scale is called a log scale because each unit increases or decreases logarithmically. What this means is that if you were to go from a pH of 7 to a pH of 8 you have increased your concentration of -OH ions ten fold or from a pH of 7 to a pH of 9 would be a 100 fold increase of -OH concentration. Incidentally, pH refers to a mathematical equation where p is the inverse log of H+ (acid/protons) concentration in solition. Thus we are measuring the inverse log concentration of H+ ions or simply put: pH.The equation looks like the following: pH = -log[H+]
Verners are a measuring device used to measure size that is based on the log scale.
The Ph scale doesn't have units it's a model to show where solutions rank based on the -Log of the concentration of H+ ions
It is a coordinate system or graph paper in which one axis (usually the y-axis) is to a logarithmic scale and the other (x-axis) is "normal".
Well...zero isn't really the lowest number on the pH scale. To simplify things, we teach kids that the scale goes from 0-14, but in reality, a solution can have a negative pH. The pH is the negative log of the hydrogen concentration or -log[H+]. So for -log[H+] to be negative, log[H+] has to be positive; therefore, [H+] would have to be greater than one. A solution that has a negative pH is extremely acidic! For example, a solution with a hydrogen concentration of 2.2 M would have a pH of -log[2.2] = -0.342 The reason we use 0-14 in abstraction is because pH + pOH = 14
Semilog (applied to a graph) means that one scale is logarithmic, the other not. The prefix "semi-" means "half" or "partially". The scale that is not logarithmic is, of course, linear.
