Question 3

1) What is the H+ concentration for an aqueous solution with pOH = 4.09 at 25 ∘C? Express your answer to two significant figures and include the appropriate units.

2)

Arrange the following aqueous solutions, all at 25 ∘C, in order of decreasing acidity.

Rank from most acidic to most basic. To rank items as equivalent, overlap them.

Ph=5.45 POH=8.55 .0018MKOH .0023 M HCL

3)

At a certain temperature, the pH of a neutral solution is 7.33. What is the value of Kw at that temperature?

Express your answer numerically using two significant figures.

Solutions

Expert Solution

1.   pH = 14 - pOH

pH = 14- 4.09
pH = 9.91
H+ concen = 10-pH
H+ = 1.230 X10-10


so in words:
pH is equal to 14 minus the pOH. this is because the pH scale is out of 14.
next, the H+ concentration is equal to 10 raised to the negative pH.
Just plug in these numbers into these formula .
