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! :)
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.
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).
