What is the pH of a cleaning solution with a H3O 7.4 10-9 M H3O?
By definition: pH = -log[H3O+]So pH = -log(7.4*10-9) = 8.13
What is the pH of a solution with a H3O of 7.9x10-11 M?
pH = -log[H3O+] = -log(7.9*10^-11) = 10.1
How is the concentration of hydronium related to pH?
pH = -log[H3O+]
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."
What is the pH of a solution with 0001 M H3O?
3. since the [H+]=0.001 M then pH= -log[H+] -log(0.001)=3 pH=3.
What is the pH of a cleaning solution with a H3O 7.4 10-9 M H3O?
By definition: pH = -log[H3O+]So pH = -log(7.4*10-9) = 8.13
What is the pH of a solution with a H3O of 7.9x10-11 M?
pH = -log[H3O+] = -log(7.9*10^-11) = 10.1
What formula can you use to calculate the H3O plus?
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
How is the concentration of hydronium related to pH?
pH = -log[H3O+]
What does pH measure How is pH defined?
The pH is a measure of how acidic or basic(alkaline) an aqueous solution is.Pure water is neutral, with a pH = 7. Things with a pH 7 are basic.The theoretical pH of an aqueous solution is defined this way:pH = -log10 [H3O]Related Information:The pH approximates the negative logarithm, base 10, of the Hydronium ion (H3O+) molar concentration of an aqueous solution. It's an indicator of the relative acidity or basicity (alkalinity) of the solution.What makes a solution acidic is the amount of H3O+ in it. A highly acidic solution will have a high concentration of H3O+, and so it will have a low pH. A basic solution has a very low concentration of H3O+, and so it has a high pH. Note that H3O+ and H+ really refer to the same thing, but H+ doesn't actually exist by itself in water: it immediately combines with an H2O molecule to form H3O+ instead.Substances with very high, or very low, pH are dangerous to human hair, eyes, and skin.Examples: pH of common substances are:Stomach acid -- 1Lemon juice -- 2.2Pure water -- 7Milk of magnesia -- 10.5
What expression represents the pH of a solution?
Concentration of hydrogen ions in the solution
What is the pH of a naturall solution?
The pH of a neutral solution is 7 and the concentration of H+ or H3O+ in the solution would be 1.0 X 10-7.

What is the H3O plus concentration in a solution that is 100 times less acidic than one having a pH of 3.22?
The H3O+ concentration in a solution with pH 3.22 = 1x10^-3.22 M or 6.03x10^-4 M.If a solution is 100 times less acidic, then the H3O+ concentration will be 6.03x10^-6 M.Put another way, 100 times less acidic will have a pH of 5.22 and H3O+ = 1x10^-5.22 = 6.03x10^-6M
The following are pH values cola 2 orange juice 3 beer 4 coffee 5 human blood 7.4 Which of these liquids has the highest molar concentration of OH?
The pH is a measure of the concentration of H3O+ in a solution. The lower the pH, the higher the concentration of H3O+. This is because of the way it is defined:pH = - log10 [H3O+]or in other words, the pH is the negative logarithm (in base 10) of the concentration of H3O+.Water, and water-based solutions have a special property: if you multiply the concentration of H3O+ and the concentration of OH-, you always get a constant number, no matter what. Mathematically, that is:[H3O+] * [OH-] = 1 x 10-14This also says the the two concentrations are inverselyproportional. So when one is high, the other has to be low.So, getting back to your question, we know the pH of each solution. From that we know the concentration of H3O+. Again, lower the pH, the higher the concentration of H3O+. And since the concentrations of H3O+ and OH- are inversely proportional, when H3O+ is high, the OH- concentration is low. So which solution has the lowest amount of H3O+? That's the one that has the highest pH, and that will also have the highest concentration of OH-.See the Related Questions for more information about pH, acids and bases.
What is the pH of a solution with H3O plus equals 1 x 10-9M?
pH = -log(hydronium concentration) [Hydronium is H3O.-log(1 x 10-9) = 9
