Since you've put NaCl on both sides of your reaction, do you assume the NaCl is some sort of catalyst? For what, sort of reaction, exactly? Also, like Borek: said, you're taking two common, stable solids, and assume by mixing them in water, you get a solid that can't exist (you have a disodium citrate -- but two more H, one to replace the Na and another to go -- where?) and something that reacts with water. If the world worked like that, we would all be in constant danger of an aggressive reaction. And we're not, generally. So it won't, logically. You're really going to have to explain better how you came up with this reaction.
