The pH scale is an inverse logarithmic representation of hydrogen proton (H+) concentration. Unlike linear scales, which have a constant relationship between the item being measured (H+ concentration in this case) and the value reported, each individual pH unit is a factor of 10 different than the next higher or lower unit. For example, a change in pH from 2 to 3 represents a 10-fold decrease in H+ concentration, and a shift from 2 to 4 represents a one-hundred (10 Ã- 10)-fold decrease in H+ concentration.Andreas Isaksen said:0.5 on a ph scale isnt much...
Thanks for thatâ€¦ I was doing the math in my head when I glanced down and saw your post.MalawiLover said:
No, the difference between 5.5 & 6 is the same as the difference between 4.5 & 5.nc_nutcase said:Since 7.0 is the balance pointâ€¦ and everything increases/decreases from there exponentiallyâ€¦ the difference between 6.5 & 7 is not that largeâ€¦
The difference between 5.5 & 6 will be far greater and the difference between 4.5& 5 is hugeâ€¦
