A pH scale is shown, fading from red at the left end to blue at the right. Above the scale, pOH is shown in even increments from 14 to zero, and below the scale, p H is shown in even increments from 0 to 14. Points marked are: A at 1 on the p H scale, B at 7 on the p O H scale, C at 13 on the p H scale, and D at 6 on the p H scale.
Based on log rules and the way pH is calculated, what is the difference in [OH– ] concentration between point A and point B.
