Why does blowing carbon dioxide gas into aqueous barium hydroxide , Ba(OH)2,reduce the conductivity from a strong electrolyte to a weak electrolyte ?
Explanation / Answer
Ionic equation:
H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) ? Na+(aq) + Cl-(aq) + H2O(l)
Net ionic equation - delete spectator ions
H+(aq) + OH-(aq) ? H2O(l)
A net ioinic equation shows the products and the ions that formed the product. You need to start with the empirical (or molecular) equation. Solids, liquids, gases, and weak electrolytes are products - never aqeuous!
NH4OH + HCl ==> NH4Cl (aq) + HOH (l)
OH- + H+ ==> HOH
Molecular equation:
NH4OH(aq) + HF(aq) ? NH4F(aq) + H2O
NET IONIC EQUATION:
H+ (aq) + OH-(aq) ? H2O(l)
Tap water has a higher conductivity than distilled water and bottled water because it contains trace amounts of ions, such as sodium, copper, fluoride, and chloride ions, which distilled water and bottled water do not have. Distilled water should have no ions in it, and sometimes bottled water will contain very small amounts of sodium.
Similarly, in comparison of the Kool-Aid sample and the sugar water, the Kool-Aid allows conductivity while the sugar water does not. This is because sugar, although it dissolves in water, it does not form ions, which is needed for the solution to conduct electricity properly. Kool-Aid contains several electrolytes
