Which solution is the least concentrated?
O 2 moles of solute dissolved in 4 liters of solution
Answer:
(a)
(b)
(c)
(d)
Explanation:
Hello,
In this case, we define the pH in terms of the concentration of hydronium ions as:
Which is directly computed for the strong hydrochloric acid (consider a complete dissociation which means the concentration of hydronium equals the concentration of acid) in (a) and (c) as shown below:
(a)
(b)
Nevertheless, for the strong sodium hydroxide, we don't directly compute the pH but the pOH since the concentration of base equals the concentration hydroxyl in the solution:
Thus, we have:
(b)
(d)
