sodium carbonate diagram The Student Room

I can't get the electrons to add up at all in the CO 3 and I'm completely lost where the Na comes into it, but this might be because I'm completely wrong about how it's all together. ! The carbonate ion is CO 32-. so the total number of valence electrons is: C = 4. 3 x O = 18. 2 minus = 2. ------------. 24 electrons.

Sodium carbonate Essential Chemical Industry

Sodium carbonate is either found naturally or is manufactured from sodium chloride (common salt). It has many uses, notably to make glass. Uses of sodium carbonate. Two forms of sodium carbonate (soda ash) are used -heavy and light. The light form is obtained first and some is then converted into the heavy form. Light sodium carbonate contains less than 0.5% sodium chloride. Heavy sodium carbonate is obtained by hydrating light sodium carbonate
