The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. ... When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.

Answer: pH of the given solution is 8.7.
Explanation:
For the buffer mixture, initial pOH will be given as follows.
pOH =
=
=
= 5.523
When 0.05 mol NaOH is added to this buffer solution then concentration of species present will be as follows.
0.05 mol 0.25 0.75 0
0 0.20 (0.75 + 0.25) 0.05
Hence, the volume of solution will be 1 liter.
[BOH] = , [Salt] =
So, pOH = [/tex]
= 6 - 0.69
= 5.30
Now, we will calculate the pH as follows.
pH = 14 - 5.30
= 8.7
Thus, we can conclude that pH of the given solution is 8.7.
