Two samples were obtained from two different societies. The ratio of hydroxyl ion in the samples is 1:5 (Society : Society 2). The pH of the sample obtained from society 1 is 5.9. What is the pH of the sample from society 2? (round up to 1 decimal place)
  • a)
    6.5
  • b)
    6.7
Correct answer is between '6.5,6.7'. Can you explain this answer?

Two samples were obtained from two different societies. The ratio of ...
(pH)1 = 5.9, (pOH)1 = 14 - 5.9 = 8.1
{OH-}1 = 10-8.1 mol/L ⇒{OH-}2 = 5 x 10-8.1 mol/L
p(OH)2 = - log{5 x 10-8.1} = 7.4
pH2 = 14 - 7.4 = 6.6
