What is the name of the compound with the formula #Na_2CO_3#?

Answer 1

#"Sodium carbonate........."#

The salt derives from #Na^+#, and #CO_3^(2-)#. #CO_3^(2-)# is called the carbonate ion You will need 2 sodium ions (#Na^+#) to even out the charges:

#2Na^+ +CO_3^(2-) ->Na_2CO_3#

Bicarbonate, also known as sodium hydrogen carbonate, is:

#Na^(+) +HCO_3^(-) ->NaHCO_3#
