It's something to do with the weathering process. Eg. At night it's really cold, and in the day it's really hot. Because the temperature keeps changing dramatically day in and day out, the sand dunes start to be sort of hacked or re-shaped, or even formed.

Assume that acid rain has lowered the ph of a particular lake to ph 5.0. what is the hydroxide ion concentration of this lake?
Ray Of Light [21]

That acid rain has lowered the ph of a particular lake to ph 5.0. the hydroxide ion concentration of this lake is

1 × 10^-9 mol of hydroxide ions per liter of lake water

 pH  +  pOH  =  14

 pOH  =  14  - 5

 pOH  =  9.00

 pOH  =  -log [OH⁻]

[OH⁻]  =  10^-pOH

[OH⁻]  = 10^{-9} mol

Therefore,

the hydroxide ion concentration of this lake is 1 × 10^-9 mol

9. The hydrogen concentration of a solution is 5 x 10-8. What is the pH?
maria [59]

Answer:

pH = 7.30

Explanation:

You can find the pH using the following equation:

pH = -log[H⁺]

In this equation, [H⁺] represents the hydrogen ion concentration. You can plug the given value into the equation and solve to find the pH.

pH = -log[H⁺]

pH = -log[5 x 10⁻⁸]

pH = 7.30
