pH = -log [H+]
So collect the hydrogen gas in a syringe and measure the volume.
Moles of hydrogen can be found using;
n = PV / RT
Pressure should be 1atm
Temperature will be around 293K
R is 8.314 * atm/mols
V is the reading on the syringe
Now that n (of hydrogen gas) is calculated we can find the moles of hydrogen ions using a stoimetric (balanced) equation
With that done use;
C = n/V
V being the volume of the solution that you electrolysed
The C is the concentration of H+ ions and now can be subed into the equation;
pH = -log [H+]
to give pH

What does the pH of a dilution measure?
pH is a measure of the hydrogen ion (H+) activity in a solution.
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
What is the pH solution defined as what of the hydrogen ion concentration?
The pH is a measure of the activity of the ion H+ in a solution.
What is the system devised to measure the hydrogen ion concentration in a solution?
pH
What scale measures the concentration of hydrogen ions?
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
What are the advantages of using glass electrode for determining pH of solution?
The advantage of using the glass electrode for determining the PH of a solution is because the glass electrode is very sensitive to any change.
What is the measurement of hydrogen ion concentration?
A measurement of hydrogen ion concentration is pH, which equals-log[H+], which is the negative logarithm of the hydrogen ion concentration (actually activity, but that is usually ignored). This quantity can be measured with a hydrogen electrode (as found in a pH meter), which is a type of ion selective electrode.
What receptor can detect changes in hydrogen ion concentration?
A chemoreceptor can detect changes in hydrogen ion concentration.
What does the pH of a dilution measure?
pH is a measure of the hydrogen ion (H+) activity in a solution.
Ph meter is an electronic instrument with an electrode that is sensitive to the what ions?
The pH meter measures the concentration of hydrogen ions (H+) in an aqueous solution
How can hydrogen be used as pH indicators?
The negative logarithm of the hydrogen ions activity is a measure of pH in the solution.
What can measure pH?
The concentration of hydrogen ions
Can you find the pH level of the inside of a plant?
Yes, using a pH-meter and a special designed combined electrode.
What does the pH scale measure the concentration of?
The pH scale is a Science indicator, Not a Mathmatical one :-)
Is pH chemical?
The pH is a measure of the hydrogen ion (H+) activity in a solution.
How can you measure the pH of an unknown liquid?
It is very easy to measure pH using a pH meter.
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
