H3O+ versus H+

Postby Katie Nye 2F » Mon Dec 07, 2020 5:24 pm

When calculating pH, I have seen calculations that use the concentration of H+ and calculations that use the concentration of H3O+. Is there a different calculation between the two? Or are they different because the question provided different information?

They are essentially the same thing. Lavelle likes to be more specific and say H3O+ because H+ ions wouldn't just be floating around in water, they would react with the water to make the hydronium ions. So H3O+ is just being more realistic I would say.

Both technically mean the same thing, but I would note that H+ is a shorthand of H3O+. The actual interaction causes the formation of H3O+ when water reacts with the H+ from an acid, but both should be acceptable. I hope this helps! :)

I believe they're referring to the same thing.

Most of the time, H+ is referring to H3O+. It is just a shorter way to write it. You have to remember that there is interaction with water H2O, so when you have that additional H+, you get H3O+ Hydronium.

Both mean pretty much the same thing. I think H+ is used as shorthand for H3O+ in the same way that we say "pH of 7" rather than "-log(1.0 x 10^-7)". One is just a more descriptive form of the other.

I think [H30+] and [H+] are basically the same thing, they are just different ways to represent proton concentrations.

They are the same thing, the only difference is that, experimentally, H30+ is technically more accurate given that is what is happening at a molecular level (the water molecule gains a proton, lowering the pH of the solution rather than just a H+ ion floating around in solution).

Pragmatically, you can think of them as the same thing when solving problems.

They are the same thing when it comes to solving acid and base problems.

It's just the difference between specifying if the H+ ion is bonded to the water or not. I think Dr. Lavelle wants us to practice using the full hydronium ion since the proton would be binding to a water molecule.

They are basically the same thing. When we say we donate a proton, typically means donating an H+ which will form H3O+, so theyre essentially saying the same thing.

Dr. Lavelle suggests that we treat them both as the same thing:) so [H+] and [H30+] are the same!
