What Is the Net Ionic Equation for the Reaction Ba(OH)2 + H2SO4 ===> BaSO4 + 2H2O?
Dear friends: Like many of yourselves, I try to help students by answering their questions. In this question, it comes down to: What are they to know, and how are they to know it? In particular, what does a test grader want to see:
2H+ + 2OH- ===> 2H2O, or
H+ + OH- ===> H2O
Glad of your help.
I agree with Kumifo. Let me extend the question to ask: What are teachers in the "real world" taught to accept? What do textbook publishers and test preparation companies accept?

I wouldn't mark either of them wrong, but personally, I prefer to see the second equation. It uses the simplest possible coefficients and shows at a glance that you only need 1 unit of each of the H^+ and OH^- ions. This eliminates possible ambiguity, and it looks a little neater.
But as said before, neither equation is wrong, in my eyes.

You wrote the equation incorrect. Cu disappears interior the products. in case you meant CuSO4 and CuCl2, then it rather is it: known: CuSO4 + BaCl2 --> CuCl2 + BaSO4 internet ionic: SO4-2 + Ba+2 --> BaSO4 :D I have been given slightly puzzled because of the fact once you assert stability it rather is many times coefficients, however the formula for the induvidual molecules necessary to be fastened instead. All have a coefficient of a million, if the molecules are top.
