What is hydrogen sulfide pH VALUE?
Hydrogen sulfide (H₂S) is a weak acid in aqueous solution, and its pH value depends on the concentration of H₂S and the presence of other ions in the solution. When dissolved in water, hydrogen sulfide partially ionizes to form hydrosulfide (HS⁻) and sulfide ions (S²⁻), which can lower the pH, typically resulting in a pH value below 7. However, the exact pH can vary widely based on concentration and environmental conditions.
What is the pH of a 0.140 M solution of oxalic acid?
14For any acid pH always
What is the pH value of electricity?
Electricity itself has no pi-Hydronium (pH) number. pH is a property that only applies to electrolytes (ionic compounds: acids, bases, and salts) dissolved in a water solution. It is a result of partial disassociation of water molecules under the electrostatic influence of the ions of the solute material(s) into hydronium (H3O+) and hydroxyl (OH-) ions.
What microbe appear white on mannitol salt agar?
Staphylococcus aureus is a bacterium that appears white on mannitol salt agar due to its ability to ferment mannitol, which produces acid. This acid production causes a change in the pH indicator in the agar, turning it from red to yellow for most staphylococci, but white for S. aureus.
What is the purpose of phenolpthalein?
Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
What s a pH value of 1?
acid

What is the name for a substance in the pH scale that is under 7?
It`s called acid(such as HCl,,,,PH=1)
Is NO3 a base or acid?
NO3- is a pH neutral ion as it s the conjugate base of a strong acid.
What part s of the digestive system have secretion with a pH of 2?
The stomach, particularly the acid that the stomach makes, typically has a pH of around 1 to 2, the lowest of the digestive system.
the pH level of greg´s bodliy fluids is low. what does that mean?
his fluids are acid -apex
Can limestone be used to lower water PH?
No, lime is a base chemical not an acid compound. Acids lower Ph, base raises Ph. Besides limestone is s stone not lime.
A scientist wants to test how much of an acid can be added to a solution before the pH of the solution changes to below a certain point. The starting pH of the solution is 6.0 and the s?
The scientist can gradually add the acid to the solution, measuring the pH at each addition, until the pH drops below the desired point. By monitoring this change, the scientist can determine the maximum amount of acid that can be added before reaching the desired pH. Controlled conditions and accurate measurements are essential for reliable results.
What is pH of a substance?
The pH of a substance tells if it's an acid, neutral, or a base. With all deference to the asker and to the previous answerer, technically substances don't have pH's. Aqueous solutions have pH's, and the pH tells you (on a logarithmic scale) the concentration of H+ (or more precisely H3O+) in that solution. A substance is an acid if it lowers the pH of a solution when it is dissolved. It does this by donating protons (H+'s) to water molecules to create more H3O+. A substance is a base if it increases the pH of a solution by accepting a proton from water molecules to form OH-. H3O+ and OH- are in equilibrium with each other in solution, so the more OH- you create, the less H3O+ will be in solution and the higher the pH. So a better answer to the question is that "The pH of a solution tells you if its an acidic, neutral, or basic solution."
Which is the most acid likely pH for a solution of a weak acid?
The most acidic likely pH for a solution of a weak acid is around 3-4. This is because weak acids only partially ionize in water, resulting in a lower concentration of H+ ions compared to strong acids.
What is a neutralzation reaction?
A neutralization reaction occurs between an acid and a base. As you may know, acids have a pH between 0 and 7, neutral substances have a pH of 7, and bases have a pH between 7 and 14. In a neutralization reaction, the pH's of the reactants are such the product(s) has/ have a pH of 7.
