Title: How would you quickly determine whether a cleaning agent contained sodium carbonate or sodium phosphate? Post by: tremack on Nov 10, 2012 How would you quickly determine whether a cleaning agent contained sodium
carbonate or sodium phosphate? Clearly, hitting the agent with acid will result in bubbles only with sodium carbonate. Na2CO3(s) + 2H (aq) ΒΈ H2O + CO2(g) + Na (aq) Title: How would you quickly determine whether a cleaning agent contained sodium carbonate or sodium phosphate? Post by: Junior. on Nov 10, 2012 OK. You've answered your own question. Sodium carbonate and an acid will generate CO2 gas, and it will be visible as bubbles. With Na3PO4, no bubbles.
Your equation is a bit sketchy. Na2CO3(s) + HCl(aq) --> NaCl(aq) + CO2(g) + H2O(l) net ionic: Na2CO3(s) + H+ --> Na+ + CO2(g) + H2O(l) |
