∙ 14y agopH is approximately defined as
pH = - log10(concentration of hydrogen ions in mol/litre)
(note the minus sign in that equation). Therefore,
concentration of hydrogen ions in (mol/dm3) = 10-pH
For pH 10 therefore:
[H+] = 10-10 mole/dm3
Wiki User
∙ 13y agoBy definition [H+]=10-pH so pH = -log[H+].
So for 10 M HCl >>> pH = -log(10) = -1.0. This is only of theoretical importance because pH formula are for ideal solutions, which are only valid for diluted, not concentrated solutions. Also a pH-meter will not give relyable measurements at pH << 1.0 or below.

∙ 13y agoA pH of 10 means that there are 1x10-10 moles/liter of H+ in the solution. pH is the negative logarithm of the hydrogen ion concentration.

Describe the construction of calomel electrode?
It consists of tube in the bottom of which is a layer of mercury ,over which is placed a paste of Hg+HgCl2.The remaining portion of cell is filled with a solution of normal or decinormal or saturated solution of KCl. a platinum wire dipping into the mercury layer is used for making electrical contact. the side tube is used for electrode is formulated as;Hg,Hg2Cl2,KCl. the electrode can be coupled with the hydrogen electrode of unknown pH.
How should the values found using the zinc electrode as a standard compare with those based on the standard hydrogen electrode?
Perhaps a rephrasing of the question would help; I've never seen a hydrogen electrode so I don't know how it compares to zinc. The process being done would probably also help (are you electroplating or separating oxygen from hydrogen or ...?), as would the solution the electrodes are immersed in (does the solution react with zinc at room temperature, is it being used in a gas, ...?)
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
What type of electrodes are used in potentiometric titration?
Potentiometric titration is a method to detect potential difference between the indicator electrode and reference electrode and thus determine concentration of chemical component, which reacts with reagent added to a solution potentially in equilibrium at the beginning.The popularly used reference electrode is either silver-silver chloride or mercury sulfate electrode, and the indicator electrode is generally made of glass electrode, platinum electrode and silver electrode or ion selective electrode.
What is the basic technique or basic principle of amperometric titration?
The potential applied between the indicator electrode and the reference electrode is kept constant and the current through the electrolyte cell is then measured on addition of each increament oftitrating solution.
What is difference between standard hydrogen electrode and normal hydrogen electrode?
E(SCE)-E(H)=241 mV @25°C SHE is a primary standard electrode bt SCE is secondary reference electrode use for more easier work than SHE & SCE,s potential also measured by taking SHE as reference electrode.
The measurement of the concentration of hydrogen ions in a solution is called?
Potential of hydrogen or PH

What is the effetct of ionization enthalpy and electrode potentail on the stability of d block compound?
I know the smaller the I.E. stabler the compound and in the solution we use electrode potential rather tha I.E but I m asking for reason..
What is simply a measure of how many H positives there are in a solution?
The concentration of H+ ions is given by pH, a term that stands for potential Hydrogen (it's called potential hydrogen because hydrogen ions can potentially become hydrogen gas).
