pH Measurement

Stable chemical compounds, are electrically neutral when mixed with water.
In order to form a water solution, dismember in positive or negative charged particles.
These charged particles are called "i ”. When we apply differential potential in two electrodes immersed in a
solution, it is possible to verify that positive ions (H , Na and more) will migrate to the negative terminal, that is
why we call them cations. The reverse happens with negative ions (OH , Cl and more) that will migrate to the
positive terminal and we call them anions. The ions freedom to migrate thru a solution is measured with
the solution ". Chemical compounds that produce conductive solutions are called
" ". Those that totally dissociate (strong acids, strong bases and salt) are called "

lectrolytes Strong

The others whose dissociation is not big (acids and weak bases) are called " ". For an
hypotetical chemical compound "MA" that dissociates in cations and anions , the reaction can be written as:

The extension that this reaction moves to the right or left, varies from one compound to the other and with the solution
Temperature.
For a specific temperature, there is a relation between the ions activity and the non dissociated molecules, that can vary
between 0 up to 100%. This relation is called K Dissociation and it is expressed by the equation:

K = aM * aA- / aMA (EQ-1)

Where: K =

ions activity M+.

For Chloridric acid, the is practically infinity, caused by the complete dissociation for ions and So it is a strong acid:

pH Measurement (cont.)

At 25°C the of water has a value of 10 where we can take that is the activity product (aH+) by

"K" dissociation (EQ-1)

(aOH-) is equal to ion OH-, the solution is neutral and activities of H+ and OH- must be both of 10 mols / L.
If a strong acid, such as HCl, is added to water, many ions H+ are added; this should reduce the number of ions OH-. For
example: if added HCl until the OH+ activity turns 10-2 the OH- activity must turn 10-12. The hydrogen potential scale is
Established by a definition merely operational, the acid degree or activity of ions H+ will be expressed by therm "pH”
(Hydrogenionic potential).

The pH will be defined as:

pH=-log |aH+|

If the activities of ion H+ is 10-x so pH is "x".For example, at pure water @ 25°C, the hydrogen ion activity is 10-7, so the pH
Is 7 @ 25°C.An acid solution has more ions H+ then OH-.So the ions H+ activities will be bigger than 10-7, being, 10-6, 10-5
and more. The pHof an acid solution by definition, must be lower than 7, will be 6, 5, 4...
If the OH- number exceed the number of ions H+ the H+ activity must be lower than 10-7, being, 10-8, 10-9 and more... The
pHwill be bigger then 7, will be 8, 9, 10...
To avoid solution ionic concentration modification being measured it is necessary that the current that goes thru the circuitry
composed by the galvanic cell (pH electrode) be minimum (I < 1pA), such as the voltage drop caused by the internal
resistance of the same electrochemistry cell being null, not to cause measuring errors. Such condition restrict the choice to

had an acid reserve and/or alkaline. Selected solutions are used as standard for calibration of ph meters based on operational
definition. They are fixed points that define the pH scale. Composed, usually, by a weak acid mixed with its own strong base salt.

Oxide Redox Potential Measurement

In order to measure potential redox it is used metallic electrodes, generally Platinum or Silver. This type of
electrode refers to chemical reactions in solutions that operate only by electrons transference. Such reactions
occur with composed elements presenting two or more oxidizing stages. Ex.: Fe2+ / Fe3+. The redox
measurement applications in a determined process, complies with previous knowledge of certain factors:
presence of infectants capable of competing with the main redox reaction, approximate values of the ions activity
coefficients entering the final equation of the potential differential, approximate speed of the reaction to be
controlled, necessary or not to control the pH. At Oxide reduction systems where the ions H+ take part at the
reaction, the redox potential depends on the pH. In order to obtain a complete description of such systems it is
necessary to indicate, besides the reference electrode, the pH value. The temperature has two effects over the
redox potential. First it enters as a factor over the logarithem of equation. This means that a determined
reason of the ionic activity, the electrode will develop a different potential. Second, the temperature influence the
Ionic activity on each ion of the solution.

Equipment Maintenance

For instrument cleaning, use isopropilic alcohol, using a clean tissue and drying it just after. After this operation, it is
suggested to use a clear wax using a fine tissue and wax the instrument body but not the tactile membrane keyboard.
Remove excess wax from the body, polishing it.

Electrodes Maintenance

1 - For storage purpose the electrodes must be dipped at the same electrolyte reference solution as used internally at the
electrode, with Electrolyte Fill Hole (9) closed.
2 - In order to avoid Reading errors, the Bulb (1) and the Punctual Ceramic (3), must be always cleaned.
3 - For cleaning purpose, wash the electrode using neutral detergent, rubbing with your own fingers and rinse it using
plenty of distilled water. Dip the electrode for about 15 minutes in Thiourea Solution and after this, dip it for 15
minutes in PEPSIN Solution.
4 - If necessary dip it for 5 minutes in HCl 0.1N and for 5 minutes in NaOH 0.1N. Repeat this operation and then rest the
electrode for 30 minutes in 3 MKCl.
5 - In case noticed that the internal Electrolyte Reference is hazy or contaminated, replace it by removing the internal
reference, using a syringe through Fill Hole (9) and wash the electrode internally using distilled water. Repeat this
operation 3 times, then refill the electrode using the appropriate internal reference, depending on the electrode type.
6 - The membrane (1) must be cleaned manually using lint free absorbent paper. Any grease should be removed using
benzine, or any other solvent.
7 - For though dirt, use Chloridric Acid 0.1N and or suphochromic solution. After this, leave the bulb of the electrode
submersed for 12 hours, then dip it in 3 MKCI solution.
8 - Dehydrated membranes, must be dipped for about 30 seconds in HF (1-2%) solution, fro renewal of the gel cap. After
this, dip the bulb for 12 hours in 3 MKCI solution.
