On the outside or something like that
The Arrhenius definition of acid-base reactions, which was devised by Svante Arrhenius, is a development of the hydrogen theory of acids. ... An Arrhenius base is a substance that dissociates in water to form hydroxide (OH -) ions. In other words, a base increases the concentration of OH - ions in an aqueous solution.

Answer:
Transition from n = 4 to n = 1 corresponds to shortest wavelength.
Explanation:
Process 
A 0.9375
B 0.75
C 0.0421
D 0.1875
According to Rydberg equation for electronic transition in H-like atoms:
where, 
is wavelength of light emitted or absorbed, 
is Rydberg constant.
So, higher the value of 
, lower will the corresponding wavelength of light.
Hence process A will be associated with shortest wavelength.
Answer:
0 °C
Explanation:
The melting point of a substance is the temperature at which it changes state from solid to liquid.
Different substance have different melting point.
The melting point of ice at 1 atmosphere of pressure is very to 0 °C this is also known as the ice point.
