The strong acids are fully ionized in aqueous solution, and they contains higher concentration of hydrogen ions. Strong acids are lower pH in nature. Some examples of strong acids are:

1) Hydrochloric acid.

2) Nitric acid.

3) Sulfuric acid.

The weak acids are not fully ionized, means they are partially ionized in aqueous solution, and they contains lower concentration of hydrogen ions. Weak acids are higher pH in nature than strong acid. Some examples of weak acids are:

1) Ethanoic acid.

2) Acetic acid.

3) Nitrous acid.

Calculate the wavelength for the transition from n = 4 to n = 2, and state the name given to the spectroscopic series to which t

finlep [7]

Answer:

The wavelength for the transition from n = 4 to n = 2 is 486nm and the name name given to the spectroscopic series belongs to The Balmer series.

Explanation

lets calculate -

Rydberg equation- $\frac{1}{\pi } =R(\frac{1}{n_1^2} -\frac{1}{n_2^2})$

where , $\pi$ is wavelength , R is Rydberg constant ( $1.097\times10^7$ ), $n_1$ and $n_2$ are the quantum numbers of the energy levels. (where $n_1=2 , n_2=4$ )
