Is there a negative answer on logarithm?
Logarithms of numbers less than one are negative. For example, the logarithm of 1/2 will be negative.
Can base of a logarithm be negative?
no
What is the pH of an aqueous solution with a H plus concentration of 1 X 10-3 M?
3: The negative of the logarithm (base 10) of the concentration. The logarithm of 1 is 0 and the logarithm of 10-3 is -3; the logarithm of their product is the sum of their individual logarithms, -3 in this instance, and the negative of -3 is +3.
Is it possible for a logarithm to equal a negative number?
Yes. The logarithm of 1 is zero; the logarithm of any number less than one is negative. For example, in base 10, log(0.1) = -1, log(0.01) = -2, log(0.001) = -3, etc.
Why log 0 is minus infinity?
The logarithm of zero is defined as approaching negative infinity because logarithmic functions represent the exponent to which a base must be raised to produce a given number. As the input to the logarithm approaches zero from the positive side, the exponent needed to achieve that value becomes increasingly negative. Therefore, ( \log_b(0) ) tends toward negative infinity, indicating that no finite exponent can result in zero when using positive bases.
How is the numerical value of pH determined and how does its magnitude relate to acidity or basicity?
The pH scale measures how acidic or basic a substance is. The numerical value of this scale is the negative base 10 logarithm of the concentration of hydrogen ions.
How can hydrogen be used as pH indicators?
The negative logarithm of the hydrogen ions activity is a measure of pH in the solution.
Is the pH of solution is the negative logarithm of its hydroxide ion concentration?
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
What are characteristics of pH?
pH is the negative logarithm of the hydrogen ion activity in a solution.
Why is there a minus sign on the definition of pH?
pH of a solution is the negative logarithm of the hydrogen-ion concentration
PH is the negative logarithm of the?
PH is the negative logarithm of the hydrogen ion concentration in a solution. This measurement is used to indicate the acidity or alkalinity of a solution on a scale of 0 to 14, with lower values representing higher acidity and higher values representing higher alkalinity.
What does -log represent in the pH formula?
The -log in the pH formula represents the negative logarithm base 10 of the concentration of hydrogen ions in a solution. It is used to convert the concentration of hydrogen ions into a more manageable scale for measuring acidity or basicity.
Is there a negative answer on logarithm?
Logarithms of numbers less than one are negative. For example, the logarithm of 1/2 will be negative.
Can base of a logarithm be negative?
no
What expression is used to represent the concentration of OH- ions?
pOH is the expression used to represent the concentration of OH- ions. It is calculated as the negative logarithm of the hydroxide ion concentration in a solution.
What is the expansion for pH?
pH=potential of HydrogenIt is a negative logarithm to the base 10 of hydrogen ion concentration.For example the concentration of hydrogen ions in water is 1.0 x 10-7 g ions/litre.This is expressed as-log10(1.0 x 10-7)=7Water has a pH value of 7.
What is the meaning of pH and why is the H a capital letter?
the p stands for "negative logarithm" or -log, a mathematical function. the H is the chemical symbol for hydrogen, in the case it represent the concentration of hydrogen ions (H+) in a solution. pH is the negative logarithm of the hydrogen ion concentration or -log[H+]. This is a good measurement of acidity or alkalinity as acids increase the H+ concentration and bases decrease it.
