A solution with pH = 2 is more acidic then one with a pH = 6 , by a factor
Options
(a) 4000
(b) 5000
(c) 8000
(d) 10000
Correct Answer:
10000
Explanation:
pH = -log[H⁺] ,
⇒ 2 = -log[H⁺]₁, and 6 = -log [H⁺]₂
⇒ log[H⁺]₁/log[H⁺]₂ = 10⁻²/10⁻⁶ = 10⁴ = 10,000.
Therefore,acidity is more in pH = 2 than pH = 6 by an order of 10,000.
