Im fed up with this assignment please help

The oxide formed when selenium burns in air dissolves in water to give a solution of selenious acid, H2SeO3. The solution conducts electricity, and turns blue litmus paper red.

State the evidence that supports classifying H2SeO3 as an acid, and identify the positively charged ion present in an aqueous solution of the acid.



Blue litmus turns red is an acid indiator.

H ions are the acid part of the molecule.


If you are fed up on this easy stuff (easy= memorization), you ought to drop the course now, and avoid grief when you have to start thinking and analyzing.
