In the English alphabet, each letter has a pronunciation (or many) as well as a name (that is used when referring to the letter as an entity, when spelling, etc.). As far as I know, in Japanese, the kana have a pronunciation only and each kana's name is its pronunciation.
So my question is, "How do you verbally refer to a specific kana in Japanese?"
Specifically, I'm particularly interested in how to refer to ん (given that it represents a nasal sound and has no pronunciation by itself) and を (given that it sounds the same as お).
For example, how would one speak the following sentence:
How do you read "ん" and "を"?
By the way, if the above sentence is not grammatical or unnatural, please correct me.
