Eli5: why is ph scale 7 considered the neutral point?

379 viewsChemistryOther

So why is 7 the neutral value on this scale?

Wouldn’t it been easier to have it as 0 so every negative number was considered acid and so on?

Its not a linear scale. And therefore, it doesnt go from 0 to 14 (or rather – 7 to 7 as u suggest) but rather, it goes from 10^0 to 10^14. This is logarithmic scale.

Thats the easiest i can deconstruct this :

pH = | log(conc of H+ ions) |
