Hi

my qestion is

in the non metal oxides there is one exception that is the oxide of hydrogen,What do we call this oxide ? WHat is its pH?

Will it be acidic like most other non-metals reacting with water ?

A strangely worded question.And I don't know what you mean by "one exception." One exception to what? I suppose you are referring to H2O which we call water (or dihydrogen oxide). The pH of a pure water solution is 7.0
