What else can I help you with?
What is a numerical symbol used to represent the negative logarithm of the number of hydrogen ions present in 1 liter of a solution?
pH 0-14
How do you calculate from scientific notation to pH?
take the negative logarithm ex. 10^-4 has a pH of 4
What does a negative number plus a negative number equal?
A negative plus a negative still gives a negative answer.
What does a negative number multiplied by a negative number equal to?
A positive number. Positive Number x Positive Number = Positive Number Positive Number x Negative Number = Negative Number Negative Number x Negative Number = Positive Number
Does a negative number minus a negative number equal a positive or negative number?
negative.
What are the units for measuring pH?
pH is a pure number. It doesn't have units. It is the negative log of the hydrogen ion concentration.
Is pH negative 3 is more acidic than pH positive 1?
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.
What is the pH scale which way in acid which way is alkaline?
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.
What does a negative pH indicate in a solution?
A negative pH in a solution indicates that the solution is highly acidic.
Can pH ever be negative?
No, pH cannot be negative. The pH scale ranges from 0 to 14, with 7 being neutral. A pH below 7 is acidic, while a pH above 7 is basic.
Why is zero the lowest number on the pH scale?
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.
Can there be a negative pH in a solution?
No, a negative pH in a solution is not possible as pH values range from 0 to 14, with 7 being neutral. A negative pH would imply a concentration of hydrogen ions greater than 1 M, which is not physically possible.
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+].
How will you classify a substance having pH value negative?
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.
How does one calculate the pH of the solution?
The pH is the negative log of [H+].
Can the pH of sulfuric acid be below 0?
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.
Which is more acidic pH2 or pH6 Why?
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.
