PH is the negative logarithm of the?
hydrogen
What value is used to express the acidity or icity of a solution called?
The acidity and the basicity are expressed by pH (the negative logarithm of the hydronium ion activity).
Why you need pH?
pH is used as a measurement of the concentration of hydrogen ions in a solution. pH is the negative logarithm of the hydrogen ion concentration.
How is a change in hydrogen ion concentration reflected in the pH?
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
Does the pH scale measure the concentration of hydroxide ions?
Yes, if you use a little bit of math. Take 14 minus your pH and you get the negative decadic logarithm of the hydroxide concentration.
PH is the negative logarithm of the?
hydrogen
What do H ions do to pH?
pH of a substance is directly related to the the amount of H+ ions it produces in the solution. It is the negative logarithm of the concentration of the H+ ions in the solution of a substance.
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 is the negative logarithim to base 10 of the Hydrogen Ion concentration.
What the PH?
negative logarithm of hydrogen ion concentration
How is numerical value of pH determined?
pH is minus of logarithm of concentration of hydronium ion
Why is there a minus sign on the definition of pH?
pH of a solution is the negative logarithm of the hydrogen-ion concentration
What is the formula of calculating pH?
pH = - log [H3O+]. It is the negative logarithm of the hydronium ion concentration.
How can hydrogen be used as pH indicators?
The negative logarithm of the hydrogen ions activity is a measure of pH in the solution.
How do you calculate from scientific notation to pH?
take the negative logarithm ex. 10^-4 has a pH of 4
