pH 0-14
take the negative logarithm ex. 10^-4 has a pH of 4
A negative plus a negative still gives a negative answer.
A positive number. Positive Number x Positive Number = Positive Number Positive Number x Negative Number = Negative Number Negative Number x Negative Number = Positive Number
negative.
pH is a pure number. It doesn't have units. It is the negative log of the hydrogen ion concentration.
No, pH negative 3 is less acidic than pH positive 1. The pH scale is logarithmic, so each whole number difference represents a 10-fold difference in acidity. pH negative 3 is 10 times less acidic than pH positive 1.
pH is the Negative power of H+ ions so "neutral" is ten to the minus 7th power (or pH=7) so acid is a Lower number and alkaline is a Higher number.
Zero is the lowest number on the pH scale because it represents the highest concentration of hydrogen ions in a solution, indicating strong acidity. As the pH scale is logarithmic, each whole number change represents a tenfold difference in hydrogen ion concentration. In comparison, a pH of zero signifies the highest concentration of hydrogen ions, making it the most acidic point on the scale.
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+].
A substance with a negative pH value indicates a strong acid with high concentration of hydrogen ions (H+). The lower the pH value, the higher the acidity of the substance. Negative pH values are possible for highly concentrated acids, like hydrochloric acid.
Yes. An acid will have a negative PH under the circumstance that it is a strong acid as well as it has a concentration of over 1 mol/L as using the function -log(H3O+)... If a number above 1 is entered, it will yield a negative number.
The pH is the negative log of [H+].
A pH of 2 is more acidic than a pH of 6 because the pH scale is logarithmic, meaning each whole number difference represents a tenfold difference in acidity. Therefore, a pH of 2 is 10,000 times more acidic than a pH of 6.
pH is the negative logarithm of the hydrogen ion activity in a solution.
Hydrogen ion concentration increases.
There's no limit to acidity.
