The unknown acid H2X can be neutralized completely by OH according to the following (unbalanced) equation: H2X(aq)+ OH yields X^2-+ H2O The ion formed as a product, X2, was shown to have 36 total electrons. What is element X? Propose a name for H2X? To completely neutralize a sample of H2X, 35.6 mL of 0.175 M OH solution was required. What was the mass of the H2X sample used?
