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 is log -10 display an error on the calculator?
In the real numbers, the logarithm is only defined for positive numbers. The logarithm of zero or a negative number is undefined. (For calculators who work with complex number, only the logarithm of zero is undefined.) This follows from the definition of the logarithm, as the solution of: 10x = whatever "Whatever" is the number of which you want to calculate the logarithm. Since 10x is always positive, that means you can't find an "x" such that the power results in a negative number, or in zero. The same applies if you use a base other than 10, for example the number e = 2.718...
What the PH?
pH stands for "potential of Hydrogen" and is a measure of how acidic or basic a solution is on a scale of 0 to 14. A pH of 7 is considered neutral, while values below 7 are acidic and above 7 are basic. It is an important parameter in chemistry, biology, and environmental science.
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.
What are characteristics of pH?
pH is the negative logarithm of the hydrogen ion activity in a solution.
Is the pH of solution is the negative logarithm of its hydroxide ion concentration?
No, the pH of a solution is the negative logarithm of its hydrogen ion concentration, not its hydroxide ion concentration. The formula for pH is pH = -log[H+].
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.
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 expansion for pH?
The expansion for pH is "potential of hydrogen." It is a measure of the acidity or alkalinity of a solution and is calculated as the negative logarithm of the hydrogen ion concentration in moles per liter.
What is the meaning of pH and why is the H a capital letter?
pH is a measure of the acidity or basicity of a solution. It stands for "potential of Hydrogen" because it represents the concentration of hydrogen ions in the solution. The capital letter "H" is used to denote the element hydrogen in chemical formulas.
What is the abbreviation of PH?
pH is the negative logarithm of the activity of the hydrogen ion in a water solution; it is used to evaluate the acidity/alkalinity of a solution.The letter H is the symbol of hydrogen; p is very probable from power.
