Under the microscope, H. pylori (Helicobacter pylori) is a spiral shaped rod, gram negative, 3*0.5 micrometers in size, and has 4-6 flagella. They are aerobic bacteria that are responsible for 80% of stomach ulcers. Besides microscopically observing stomach (stool) samples, one can also determine the presence of H. pylori by:

culture of stomach fluid sample
urea breath test
measuring antibodies to urease in blood, saliva, or stool. However, these antibodies may persist long after the infection has been eradicated, so it is less useful than the breath test.

Another property of the H. pylori allows for the urea breath test. Since H. pylori contains high levels of urease, an enzyme which degrades urea to carbon dioxide (CO2), patients can swallow a dose of urea labeled with C13, then have their breath collected. The Collected exhale (labeled CO2) will then be measured in a mass spectrometer to determine if the concentration of CO2 indicates an H. pylori infection. This is an accurate test for H. pylori.

What ion is responsible for acidic properties of a liquid solution?

The hydrogen ion (H+) is responsible for the acidic properties of a liquid solution. In acidic solutions, there is an excess of H+ ions, which lowers the pH of the solution.

The particle responsible for acid properties in water is?

The particle responsible for acid properties in water is the hydrogen ion (H+). When an acid is dissolved in water, it releases H+ ions, which give the solution acidic properties by increasing the concentration of hydronium ions (H3O+).

What ion is responsible for acidic properties?

The hydrogen ion (H+) is responsible for acidic properties. In acidic solutions, there is a higher concentration of H+ ions, which gives the solution its characteristic sour taste and ability to conduct electricity.

What Properties do Arrhenius acids have in common?

Arrhenius acids have common properties of producing hydrogen ions (H+) when dissolved in water and increasing the concentration of H+ ions in a solution. They also have a sour taste and can conduct electricity.
