What are some common logarithmic scales?
The Decibal scale for sound measurement is an example of a logarithmic scale. The Richter scale, the pH scale, the magnitude scale for stars, the multiplicative scales on a slide rule
Formula for calculation pH and pOH?
pH + pOH =14
What is the formula for a cube?
S=ph+2b
What type of substance have a pH between 1 and 6?
Acids.
What are logarithms used for today?
Here are just a few modern uses for logarithms:The Saffir-Simpson Hurricane Scale, Richter Magnitude Scale, and pH scale are all based on logarithms.You see brightness on a logarithmic scale, so as light becomes constantly brighter, it starts having less relative affect on your vision.Musical notes are measured logarithmically, and the frets on a guitar grow closer together as the notes become higher in pitch.Engineering data is sometimes graphed on a logarithmic scale.
Give an example of logarithmic formula that give the pH of a substance?
pH=-log(H+)
How is pH scale applied to logarithmic equation?
It isn't. It is how acidic or basic a substance is.
A substance with a pH of 11 is what times more what than a substance with a pH of 8?
A pH of 11 is 1000x more alkaline than a pH of 8. The pH scale is a logarithmic scale. This means that in a pH scale, a change of one whole number represents a tenfold change in the pH. So a pH of 8 is 10x more alkaline than a pH of 7.
The term pH is used in measuring?
pH is measured on a logarithmic scale of 1 to 14. 1 is the most acidic, and 14 is the most alkalinic. An acidic substance has a high amount of H+ ions and an alkalinic substance has a high amount of OH- ions.
What is the causes of acid and base?
A substance is classified as an acid or a base, based on the pH of the substance. pH is the rating of a substance compared to water, which is considered neutral. Water has a pH of 7.0. A substance with a pH less than water is considered acid and higher than water is considered a base. The pH of a substance is determined by a mathematical formula that represents the concentration of hydronium ions in a solution.
What two term determines the pH scale?
the pH scale is a measurement of acidity of liquids. it ranges from a rating on 1 to 14. when it is at 1, it is very acidic and at 14 it is a strong alkali but at 7, its neutral like water. the pH scale also shows acidity by colour- at 1 it is a strong red, at 7 it is a green and at 14, it is a purple. ;)
If solution a has a pH of 5 and solution b has 100 times the hydrogen ion concentration of solution A what is the pH of solution B?
3. pH is a negative logarithmic scale. Therefore a difference of 100 times more is translated to -log(100) = -2. Recall the formula pH = -log([H+]).
PH is expressed in units of?
pH, technically, is unitless due to its logarithmic nature. However, some prefer to say that pH 14.0 is '14 pH units'.
How is each step on the pH scale different?
The pH scale is logarithmic; the difference between two units is x10.
What is pool pH?
pH is the hydrogen or hydroxide concentration in your pool. pH is a logarithmic scale ranging from 0-14 and 7 being neutral.
If the ph of a substance is 11 then that substance is?
If a substance has a PH of 11 then the substance is basic.
Is a solution with a pH of 2 twice or half as acidic as a pH of 1?
No. As the pH scale is logarithmic, a solution with a pH of 1 is 10 times more acidic than a solution with a pH of 2.
