.what are carbonates and acid carbonates??

Question

any example equations?

Answer 1

Carbonates contain the (CO3)2- ion.

Acid carbonates or hydrogencarbonates contain the HCO3- ion.

Answer 2

Carbonate are salts of acid carbonic and a metal, such as

CaCO3, CuCO3, Na2CO3...

Most of carbonates are insoluble in water (except for those of Alkali)

Carbonic acid (acid usually end with a "ic", not an "at"), well are the acid of CO2

Answer 3

>>

.carbonates are compounds containing the carbonate ion..

.acid carbonates are compounds containing the hydrogen carbonate ion..

.just as acid-base reactions are an important type of double substitution reaction, the reactions of carbonates and acid carbonates with acids are an important subtype of acid-base reaction..

.carbonates undergo double substitution reactions with acids to form carbon dioxide and water or acid carbonatees, depending on the relative quantity of acid added:

  K2CO3(aq)  +  2 HCl(aq)  --> 2 KCl(aq)  +  CO2(aq)  +  H2O(l)

   K2CO3(aq)  +  HCl(aq)  -->  KCl(aq)  +  KHCO3(aq)

.the acid either totally or partially neutralizes the carbonate..

.carbon dioxide, an acidic anhydride, can react with a base to form a carbonate or an acid carbonate:

   CO2(g)  +  2 NaOH(aq)  --> Na2CO3(aq)  + H2O(l)

     CO2(g)  + NaOH(aq)  --> NaHCO3(aq)

.the base either totally or partially neutralizes the carbon dioxide..
