Why is the graph of log against pH a straight line?
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.
Logarithmic scales are used to measure what?
Whenever the data covers a very large range of values a log scale if very useful. Earthquakes and hearing are common examples.
The log of a quotient is the log of a numerator divided by the log of the denominator?
No. The log of a quotient is the log of a denominator subtracted from the log of the numerator.
How do you get log in the wwwfriendstercom?
to log in friendster.com
If log 12 equals 1.07918 then the anti-log equals?
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.
What is the brightness of a star measurable by a scale called?
It is called the magnitude scale. It is a log scale.
How are logarithms used in our society?
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.
Why semi log paper is named so?
One axis (usually the vertical axis) is on a log scale, the other is a linear scale.
If you have a lower pH will you have higher proton concentration?
Yes. The pH scale is an inverse log scale of the [H].
Why is the graph of log against pH a straight line?
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.
Explain how to use a Doyle log scale?
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.
Why is the PH scale called a log scale?
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+]
What are verners?
Verners are a measuring device used to measure size that is based on the log scale.
What makes up PH 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
What is a semi-log scale?
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".
Why is zero the lowest number on the pH scale?
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
Why the semi log was in linear?
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.
