Hello!
This question can be solved using the Henderson-Hasselbach equation, but first we need to know the value of pKa
pKa= -log(Ka)= -log(7,1*10⁻⁶)=5,15
Now, we apply the equation:
![pH=pKa+log \frac{[A^{-}] }{[HA]} =5,15+log( \frac{0,025M}{0,037M} )=4,98](https://tex.z-dn.net/?f=pH%3DpKa%2Blog%20%20%5Cfrac%7B%5BA%5E%7B-%7D%5D%20%7D%7B%5BHA%5D%7D%20%3D5%2C15%2Blog%28%20%5Cfrac%7B0%2C025M%7D%7B0%2C037M%7D%20%29%3D4%2C98)
So, the pH of this solution would be 4,98
Have a nice day!

The organic product formed in the reaction shown in the image would be bromoethane.
<h3>Substitution reaction in alkanes</h3>Alkanes, such as ethane undergoes a substitution reaction with halogens such as bromine to produce haloethanes.
For example, the equation of the reaction between ethane and bromine water is as below:
The products formed are bromoethane and hydrobromic acid.
