How is the pH scale shifted by the use of hydrogens ions?
pH is a measure of Hydrogen concentration pH = -log10[H+], where [H+] is the concentration of hydrogen ions. From this equation, we can see that an increase of hydrogen ions will lower the pH, and a decrease of hydrogen ions will raise the pH. =D
Does the pH scale indicate the consentration of hydrogen ions or hydroxide ions?
pH stands for power of hydrogen and indicates concentration of Hydrogen ions. pOH indicates concentration of hydroxide ions.
How is the concentration of hydrogen ions and hydroxide ions related in aqueous solutions?
Hydrogen ions: pH under 7.Hydroxide ions: pH over 7.
How do you measure the PH value of hydrocarbon?
Since hydrocarbons do not dissolve in water, they have no pH. That is to say, they do not influence the concentration of either hydrogen or hydroxide ions. They do contain hydrogen, but the hydrogen in a hydrocarbon does not ionize.
The regulation of pH is the control of which ions?
hydrogen ions.
Which ions do not affect ph of a solution?
Any ion that doesn't undergo hydrolysis in solution, and other than hydrogen and hydroxyl ions, does not change the pH value of the solution. Eg: alkali metal ions
What does the pH scale measure the concentration of?
The pH scale is a Science indicator, Not a Mathmatical one :-)
How does the phosphate buffer system help in maintaining the pH of our body?
The phosphate buffer system consists of two ions: dihydrogen phosphate ions and hydrogen phosphate ions. When the number of hydrogen ions in a body's bloodstream increases (pH drops), hydrogen phosphate ions accept hydrogen ions in order to maintain the equilibrium between the concentration of hydrogen and hydroxide ions within the bloodstream. When the number of hydrogen ions in the bloodstream decreases (pH increases), the resulting dihydrogen phosphate ions release hydrogen ions in order to increase the number of hydrogen ions in the blood.
When the pH is high what is true about the concentration of hydrogen ions?
A numerically high pH , the hydrogen ions are very low . e,.g, pH 12 is a very alkaline solution. A numerically low pH , the hydrogen ions are very high . e.h. pH 2 is very acidic .
What the pH number of an indicator for the concentration of?
The pH value is an indication of the acidity/alkalinity of a solution. More precisely, the pH value is a representation of the concentration of hydrogen cations (hydronium ions) in a solution.
Is it possible for a solution to have a pH value less than 0?
pH is roughly minus log (molar concentration of hydrogen ions) so pH=7 means molar concentration = 10^-7 M This means that a pH of 0 corresponds to 1 mole per litre of hydrogen ions and that yes the pH can go negative. e.g. 2 moles per liter of hydrogen ions means pH= -0.3 but clearly there is a limit to how many hydrogen ions you can fit in a liter. 10M HCl has a pH of -1 The most negative pH for a real solution that I could find is -3.6
How do ions relate to something's pH?
The pH is related to the activity of hydrogen ions (H+) in a solution.
