Aitch-two-O

Yes. Water.

thank you

so, it is acceptable to write it like that ? (I know that it sounds like the letters in the formula)

You wouldn't write it that way in any serious context. It might be acceptable in a humorous piece of writing.

Thank you!

Would it be acceptable in the context of a story aimed at 12-13 year old science students?

Only use it in a funny story. "Aitch" sounds like something painful, like "ache."

This seems to me to be a representation of a cockney pronunciation, beginning with a broad A. What do you think, A

A cockney would say Haitch.

How do you say it?

Blue JayA cockney would say Haitch.

With the H? I thought they dropped the initial h. As 'enry 'iggins' in "My Fair Lady".

Yes. They drop the H when it should be there, and sometimes insert it when it shouldn't be there.
RP speakers say Aitch, but many other Brits say Haitch. It is said that in Northern Ireland the Protestants say Aitch and the Catholics say Haitch, which enables you to tell them apart.
