Question

7. What does the term 'hydrate' mean? What would a pentahydrate formula be? How many water molecules are included in the formula? Draw the structure of oxalic acid (ethane dioic acid) C2H2O4. 8. 9. When the hydrogens on this molecule are removed with the help of ammonia as a base what will the charge on the molecule be? Draw it. 10. Look at the charge on cobalt and the charge on the oxalate ion you drew. What do yor now expect the formula of cobalt oxalate to be? 11. What type of bonding is taking place in this compound?

Answer 1

hydrate means water molecules: penta hydrates means 5 H₂O [Xosho ® ethane dioic acid C2H24 O=c-O-H O= CO-

Oxalic acid with NH₂ COOH COOH 7 43 őoo 030-0=o i oxalate anion - Cobalt ion = Cota Cobalt Oxalate is Cota lonic bond aco takes Place
