Answer:
The pH of the sweater containing Hydrogen ion concentration
is
<u>8</u>
<u></u>
Explanation:
pH = It is the negative logarithm of activity (concentration) of hydrogen ions.
pH = -log([H+])
Now, In the question the concentration of [H+] ions is :
use the relation:
pH = 8
Note : <em><u> 1 times 10 to the power of 8 must be" 1 times 10 to the power of -8"</u></em>
If the concentration is
Then pH = -8 , which is not possible . So in that case the pH calculation is by other method
Answer:
2
Explanation:
Half-life
Concentration
We have the relation
So
Comparing the exponents we get
The order of the reaction is 2.
The rate constant is
