✦ Synopsis

The reaction products obtained by treating C A'nH20 with various . . . . . . 4 ° inorgan~c salts and acid-containing solutlons were characterlzed. The anions taken into consideration were+carbonates_ chlori~e,~T nitrate, sulfate and acetate. As counter-cation H , NH , Na and Ca were 4 chosen, thus obtaining different pH values according to the specific solution utilized.

C4A.nH20 gives place to two c2mpeting and reversible reactions: exchange of the interlayer OH anions according to the following selectivity sequence:

and an antacid behaviour towards aqueous solutions containing less selective anions.
