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?
In: Chemistry
The pH scale is not built around a neutral of 7. The neutral of 7 is more or less an accident. It’s not even always true – the 7 thing is just a property of water.
pH is a measure of how densely packed hydrogen ions are in the liquid. It’s a logarithmic scale so 7 is very very different from 14.
