Why is there a minus sign on the definition of pH?
pH of a solution is the negative logarithm of the hydrogen-ion concentration
Concentration of hydrogen ions in solution is called?
Concentration of hydrogen ions in a solution is called: Acid concentration and pH = - log10(hydrogen ions concentration, in mol/l)
What is the definition for pH?
pH is equal to the negative log of the concenetration of hydrogen ions in a solution. More simply, pH=-log[H+]. The hydrogen ion concentration is in moles/liter.
Do bases have a high or low concentration of hydrogen ions?
Bases have a low concentration of hydrogen ions. In contrast, acids have a high concentration of hydrogen ions.
What is the mathematical definition of pH?
pH is the negative log of the hydrogen ion (hydronium ion) concentration. It is - log [H+] or - log [H3O+]
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.
Which substances decrease the hydrogen ion concentration in a solution?
Adding a base the hydrogen concentration decrease.
What is the concentration of hydrogen ions commonly expressed as?
The concentration of hydrogen ions is commonly expressed as pH.
What is the pH of a hydrogen solution that has a hydrogen concentration of 10-2?
If concentration of Hydrogen in solution is 10-2 then its pH must be 2.
Does a acid or a base contain a higher concentration of hydrogen ions?
Concentration or quantity? Bases have more hydrogen.
What is the pH of a solution that has a hydrogen ion concentration of 110?
A hydrogen ion concentration of 110? 110 what? Or is that supposed to be 1x101
How is the Hydrogen ion concentration of stomach acid - with a pH of 2.0 - found?
The definition of pH is used, which is, pH=-logH+concentration.Since you know the pH, this turns into an algebra problem:2.0 = -logH+concentrationThen, logH+concentration = -2H+concentration = 10-2, or 1/100. The H+ concentration is 0.01 M.
