At first scientists/researchers observe a natural phenomenon. after enough observation, they make predictions why that phenomenon is happening and the reasons that lead to that particular phenomenon. then they generate scientific hypothesis to explain that phenomenon and after getting enough data they develop tests and perform experiments.

What you have to keep in mind is that
pH = - log[H+]
so 3.75 = -log[H+], we get [H+]=
,
that is [H+]≈1.77827941×
(i see this result on calculator)
this is just what you want!
