Hi everyone,
My understanding is that pure carbon is highly stable at room temperature and does not react with alkaline solutions like that of Ca(OH)2. However i am struggling to find any reference that i can quote justify this statement. Due to university shutdowns i can't even carry out this experiment. I have pure carbon in my blended cement composite that shows increased calcite content. This increased calcite content is most likely because of the carbonation of portlandite from atmospheric CO2 and not from the pure carbon present in the blended cement composite. However, i don't have a reference to cite this statement nor can i do my own experiment anytime soon. Just wondering if anybody know of any publication that i can site in regards to the stability of pure carbon in alkaline environments?
Dear Rajeev Roychand, I did not find any specific article on this, but in the Wikipedia entry on Carbon it is stated that "It does not react with sulfuric acid, hydrochloric acid, chlorine or any alkalis."
Dear Rojeev,
The recent development and market introduction of a new type of alkaline stable imidazole-based anion exchange membrane and related ionomers by Dioxide Materials is enabling the advancement of new and improved electrochemical processes which can operate at commercially viable operating voltages, current efficiencies, and current densities.
