I honestly don’t know if this I right but that would be my guess
Answer : The pH of the solution is, 5.24
Explanation :
First we have to calculate the volume of 
Formula used :

where,
are the initial molarity and volume of
.
are the final molarity and volume of
.
We are given:

Putting values in above equation, we get:

Now we have to calculate the total volume of solution.
Total volume of solution = Volume of
+ Volume of 
Total volume of solution = 160.0 mL + 1086.79 mL
Total volume of solution = 1246.79 mL
Now we have to calculate the Concentration of salt.

Now we have to calculate the pH of the solution.
At equivalence point,
![pOH=\frac{1}{2}[pK_w+pK_b+\log C]](https://tex.z-dn.net/?f=pOH%3D%5Cfrac%7B1%7D%7B2%7D%5BpK_w%2BpK_b%2B%5Clog%20C%5D)
![pOH=\frac{1}{2}[14+4.87+\log (0.0437)]](https://tex.z-dn.net/?f=pOH%3D%5Cfrac%7B1%7D%7B2%7D%5B14%2B4.87%2B%5Clog%20%280.0437%29%5D)


Thus, the pH of the solution is, 5.24

Answer:
Scientific Method.
Explanation:
A scientific method is basically a method or a process when you conduct an experiment. Normally, the process goes like this:
1. You make like a question or something that you want to investigate, it's like the aim of the experiment.
2. You make an experiment and a hypothesis. A hypothesis is basically a guess on how the results of the experiment would turn out. You don't have to be correct for the hypothesis since there is no right or wrong answer.
3. Conduct the experiment. I don't think this needs a detailed explanation since experiments vary from one another.
4. Collect results. The data you collect come in different ways based on your experiment, but it is crucial you get data so that you can answer your question in 1.
5. Make inferences. You can't directly get a conclusion or answer from the results, so inferences are needed.
6. Craft a conclusion or answer. This is the final step when conducting an experiment and the part where you have the answer you needed when you conducted the experiment :)
