A solution of oxalic acid is mixed with a solution of cesium hydroxide. This chemical reaction requires double displacement. I got this as my chemical equation:
$$\ce{C2H2O4 + CsOH -> H3O + CsC2O4}$$
My teacher says it is wrong, is it really incorrect?
Is the one below the right one?
$$\ce{C2H2O4 + CsOH -> CsHC2O4 + H2O}$$
