## anonymous 4 years ago which of the following solutions would contain the highest concentration of sodium ions? A) 0.10M sodium chloride B) 0.20M sodium carbonate C) 0.10M sodium sulfate D) 0.10M sodium phosphate E) 0.20M sodium bromid

i guess B)

First, you need to convert these concentrations into moles of each compound. You can do this using this equation...$c_i=\frac{n_i}{V_{sol'n}}$Try this first.

whats your reason for picking over E. they both have the same 0.20

4. anonymous

ci is the concentration of the species ni is the number of moles of the species V is the volume of the solution. Assume 1L.

Bis Na2CO3 it has 2 Na atoms in one molecule hence its concentration would be highest.

well i think we have to decide it with normality isntd??

7. anonymous

max. normality is of B

8. anonymous

and as far i do we have to mulitply its concn by charge to get normality dats mine reason to pick B
