When should we use logQ vs lnQ.

[Maya Beal Dis 1D]

If you are using the shortcut E=E(naught)-(0.05916/n)logQ, you need to use log. I think there is another number shortcut if you are using the equation with natural log.

Ln is easier and often used more.

If you are using the shortcut E=E(naught)-(0.05916/n)logQ, you need to use log. I think there is another number shortcut if you are using the equation with natural log.

Is this the equation given on the equation sheet?

[Celine 1F]

I don't think I saw the shortcut equation with .05916 on the equations sheet so I used Ln

[Daria MacAuslan 1H]

You usually use ln, just because it is more direct and it is also given to us on our equation sheets. If you want to use log however, just multiply by the conversion factor, it shouldn't really matter in the end

[Katie Kyan 2K]

You can use either but if you are trying to find the pH as in some of the HW problems, it would be easier to use the log version so you can find -log{H3O+].

[Anthony Hatashita 4H]

You can use either, the equation sheet lists both so whichever you are most comfortable using is best.

[Diana Andrade_4F]

You can use whichever you want to use!

[Ying Yan 1F]

When a problem is asking for you to solve for the pH or when you are given pH in a cell diagram, that's when you would usually use log instead of ln. Hope this helps!

lnQ can always be converted to logQ thru the equation: lnQ=2.303logQ
