Hello!
First, we need to determine the pKa of the base. It can be found applying the following equation:
Now, we can apply the
Henderson-Hasselbach's equation in the following way:
![pH=pKa+log( \frac{[CH_3NH_2]}{[CH_3NH_3Cl]} )=10,65+log( \frac{0,18M}{0,73M} )=10,04](https://tex.z-dn.net/?f=pH%3DpKa%2Blog%28%20%5Cfrac%7B%5BCH_3NH_2%5D%7D%7B%5BCH_3NH_3Cl%5D%7D%20%29%3D10%2C65%2Blog%28%20%5Cfrac%7B0%2C18M%7D%7B0%2C73M%7D%20%29%3D10%2C04)
So,
the pH of this buffer solution is 10,04Have a nice day!
The precipitate that forms when aqueous solutions of barium nitrate and sodium sulfate are mixed is barium sulphate.
Barium Nitrate is a colorless to white, odorless, crystalline powder. It is used in making fireworks, for green lights and neon lights, and in ceramic glazes.
Sodium Sulfate Anhydrous is the anhydrous, sodium salt form of sulfuric acid. Sodium ion is the principal cation of the extracellular fluid and plays a large part in the therapy of fluid and electrolyte disturbances.
When aqueous solutions of barium nitrate and sodium sulfate are mixed is barium sulphate, one soluble salt, sodium nitrate, and an insoluble salt, barium sulphate.

The types of proton that will cause spin-spin splitting of each other's 1H NMR signals are the protons that are not in same chemical environment.
<h3>What are the protons that cause splitting?</h3>
The NMR spectroscopy is the acronym for the term nuclear magnetic resonance. This process could only be carried out on a nucleus that has an odd number of protons such as 1-H and C-13.
The splitting would be caused by the protons that are not in the same chemical environment as others. This implies that, the types of proton that will cause spin-spin splitting of each other's 1H NMR signals are the protons that are not in same chemical environment.
