Text: Predict the acidity or basicity (basicity alkalinity or being basic) of the aqueous solution if you put some NaCl in water to make a solution acidic basic neutral cannot be predicted none of the above. Predict the acidity or basicity (basicity alkalinity or being basic) of the aqueous solution if you put some NH4Cl in water to make solution acidic basic neutral cannot be predicted none of the above. The compound Na-CO2 is just a common simple ionic compound. When we dissolve Na-CO2 in water to make a solution, the solution has high pH. Correct choice to fill in the blank below: What is the reason? Choose Answer: The reason is because Na+ (aq) + H2O(l) → NaH(aq) + OH(aq). Na+ (aq) + 2 H2O(l) → 2 NaOH(aq). CO2 (aq) + OH (aq) + H2O(l) → HCO3- (aq) + OH (aq). HCO3- (aq) + OH (aq) + H2O(l) → CO3^2- (aq) + OH (aq). HCO3- (aq) + Na+ (aq) + OH (aq) + 2 H2O(l) → NaOH(aq) + 2 H2O(l) + HCO3- (aq) + OH (aq) + Na+ (aq) + 2 H2O(l) → NaOH(aq) + 2 H2O(l) + H2 (aq).
