Hello,
I am writing to request assistance in characterizing a mineral solution that I have developed, known to possess basic properties with a pH level of 14.
My objective is to gain a comprehensive understanding of its composition through detailed analysis.
Specifically, I am interested in identifying the elemental composition, molecular structure, and any additional properties that define its nature.
Does someone have any insights or recommendations on tests or analyses that could elucidate its properties.
Thank you very much.
Hello,
A basic mineral solution with a pH of 14 is highly alkaline. The pH scale ranges from 0 to 14, with 0 being extremely acidic, 7 being neutral, and 14 being extremely alkaline or basic. A solution with a pH of 14 is at the highest end of alkalinity.
Certainly, conducting various tests and analyses can provide valuable insights into the properties of a basic mineral solution with a pH of 14. Here are some suggested tests and analyses:
- pH Measurement
- Titration
- Ion Analysis
- Conductivity Measurement
- Dissolution Tests
- Stability Testing
- Environmental Impact Assessment
- Mass Spectrometry
Dear Ines Bennour and Ali Akram derardja ,
before to discuss further, plz, answer three questions:
1. What is pH? Give a definition.
2. Can pH be higher than 14?
3. How to measure experimentally the pH of highly alkaline solutions?
Dear Yurii V Geletii
1. What is pH? Give a definition.
pH is a measure of the acidity or alkalinity of a solution. It is defined as the negative logarithm (base 10) of the concentration of hydrogen ions (H+H+) in a solution. The pH scale typically ranges from 0 to 14, where a pH of 7 is considered neutral. Solutions with a pH below 7 are acidic, while those with a pH above 7 are alkaline or basic. The lower the pH, the more acidic the solution, and the higher the pH, the more alkaline the solution. The pH scale is logarithmic, meaning each unit change represents a tenfold difference in acidity or alkalinity.
2. Can pH be higher than 14?
No, in the commonly used pH scale, which ranges from 0 to 14, pH values above 14 are not considered possible.
3. How to measure experimentally the pH of highly alkaline solutions?
Measuring the pH of highly alkaline solutions can be challenging, as traditional pH meters and indicators may not be suitable for extremely high pH values. In such cases, specialized equipment and precautions are necessary.
1. pH "is defined as the negative logarithm (base 10) of the concentration of hydrogen ions (H+H+) in a solution." Wrong!
2. Yes, pH can be higher than 14.
3. It's challenging, but possible. A common equipment with precautions can be used.
I asked these three basic questions to show how complicated would be dealing with highly alkaline solutions. I have asked the first question to more than thousand scholars in chemistry. Only three gave the correct answer.

Thank you for your answer:
These are my responses to your questions.
1- pH is a measure of the acidity or basicity (alkalinity) of a solution. It is a numerical scale typically ranging from 0 to 14, where a pH of 7 is considered neutral. A solution with a pH below 7 is considered acidic, while a pH above 7 is deemed basic or alkaline.
The pH scale quantifies the concentration of hydrogen ions (H⁺) in a solution. A lower pH indicates a higher concentration of hydrogen ions, signifying greater acidity. Conversely, a higher pH indicates a lower concentration of hydrogen ions, indicating a more alkaline or basic solution. pH can affect chemical reactions, biological processes, and the behavior of various substances in a solution.
2- Theoretically, we can have a negative pH value for very acidic solutions and a value greater than 14 for highly basic solutions, but these instances are not commonly encountered in typical laboratory or everyday situations.
3- Measuring the pH of highly alkaline solutions requires special considerations due to the limitations of conventional pH meters. However, there are methods to measure the pH of highly alkaline solutions experimentally:
Specialized pH meters: These meters might have electrodes made of materials that are resistant to high pH, such as glass electrodes
Dilution: Diluting the highly alkaline solution with distilled water to bring the pH into a measurable range

It's possible to do a mass spectrometry analysis for liquid sample?
Dear Ines Bennour .
"The pH scale quantifies the concentration of hydrogen ions (H⁺) in a solution" The quantification suggests that there is a formula linking pH and [H+]. Plz read the thread

Dear Ines Bennour .
It's possible to do a mass spectrometry analysis for liquid sample?
Yes, mass spectrometry (MS) can be used for the analysis of liquid samples. In fact, MS is a versatile technique that can analyze a wide range of sample types, including gases, liquids, and solids.
There are different methods for introducing liquid samples into a mass spectrometer, depending on the specific type of mass spectrometry being used.
Electrospray Ionization (ESI): This method is commonly used for analyzing large biomolecules like proteins and peptides. The liquid sample is sprayed into a fine mist, and the droplets are charged. The solvent evaporates, leaving charged ions that can be analyzed by the mass spectrometer.
Gas Chromatography-Mass Spectrometry (GC-MS): If your liquid sample can be volatilized, you can use GC-MS. In this technique, the liquid sample is injected into a gas chromatograph, where it is vaporized and separated into individual components. These components are then introduced into the mass spectrometer for analysis.
The choice of method depends on the nature of your sample and the information you are seeking. Each technique has its advantages and limitations. If you have a specific type of liquid sample in mind or a particular analysis goal, feel free to provide more details, and I can offer more tailored advice.
