Answer:
pH = 3; acidic
Explanation:
The equation to find pH given [H+] is:
pH = -log[H+]
In the question it gives us the concentration of [H+], which is 0.0010 M.
Now just plug this into the equation to solve:
pH = -log(0.0010)
pH = 3
This would make the solution acidic as it is less than 7.
Hope this helps!!
Answer:
63.6g/mol
Explanation:
Use the equation of effusion:
47.8/24=
solve for x you get 63.6g/mol
Using a thin stationary phase supported by an inert backing, thin layer chromatography (TLC) is a chromatographic technique used to separate the components of a mixture.
It can be carried out on an analytical scale to track the development of a reaction or on a preparative scale to purify minute quantities of a chemical. Because of its simplicity, comparatively low cost, great sensitivity, and rapid separation, TLC is an extensively used analytical method. Similar to all chromatography, TLC works on the premise that a chemical will have varying affinities for the mobile and stationary phases, which will influence how quickly it migrates. TLC aims to produce well-defined, well-separated spots.
