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.
You want to divide 10 by 4 to get the number of hours it will take for the water to get to the springs, which is 2.5, so it would take the water 2.5 hours to revel to it’s spring
Answer:
Ionic Substance is....
Explanation:
In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.
