Chemistry help please !!!!!!!!!!!!!!

Question

solid titanium (IV) carbonate hydrochloric acid

Please help with this equation

Answer 1

The carbonate ion is expected to react with acids by liberation of carbon dioxide.

CO3(2-) + 2H+ -----> (H2CO3) -----> H2O + CO2

So, we expect the reaction to proceed:

Ti(CO3)2 + 4HCl -----> TiCl4 + 2CO2 + 2H2O

However, that's not the end of the story. TiCl4, containing a high-valent metal, is easily hydrolyzed by water to give the oxide and HCl, so...

TiCl4 + 2H2O -----> TiO2 + 4HCl

If you add this to the equation above, you get

Ti(CO3)2 -----> TiO2 + 2CO2

So, in actual fact, HCl is a catalyst for the decomposition of titanium(IV) carbonate to titanium(IV) oxide and carbon dioxide.

Edit: There is no evidence that titanium(IV) carbonate actually exists.
