The Rydberg equation can be applied to any one-electron atom or ion, but the value of the Rydberg constant needs to be multiplied by the square of the charge on the nucleus:

Where is the nuclear charge.

The side chains of amino acids are responsible for giving proteins their secondary and tertiary structure (they control the way the proteins fold). The two amino acids above are largely responsible for producing the protein structures known as α-helices. However, these structures are very sensitive to the pH of the solution in which the protein is suspended. Explain why these structures are particularly sensitive to pH.

Explain why buffer potential is maximised at the pH that matches the pKa of the weak acid of the buffer. What does this have to do with buffer capacity?

With reference to the diagram below and using the theory covered in this course, describe how soap works to remove dirt from human skin.
