Question

SNL 4) Classify each of the following as non-ionized, partially-ionized, or ionized. Write each compound as it exists in aqueous solution e.g. NaCl(aq) → Na' (aq) + Cl(aq) HCl(aq) - a strong acid Ca(OH)2 (aq) - a strong base HC,H,O, (aq) - a weak acid Ba(OH)2 (aq) - a weak base 5) For the chemical reaction H2SO, (aq) + 2 NaOH(aq) → Na2SO. (aq) + 2 H20 (1) Write the complete ionic equation: Write the net ionic equation: 6) For the chemical reaction KNO, (aq) + NaCl (aq) → NaNO, (aq) + KCl (aq) Write the complete ionic equation: Write the net ionic equation:

Answer 1

4) HCl : ionized (because it is strong acid and thus dissociate completely)

HCl(aq) $\rightarrow$ H⁺(aq) + Cl^-(aq)

Ca(OH)2 : ionized (because it is strong base and thus dissociate completely)

Ca(OH)2(aq) $\rightarrow$ Ca ²⁺(aq) + 2OH^-(aq)

HC2H3O2 : partially ionized ( because it is weak acid)

CH3COOH(aq) $\rightleftharpoons$ CH3COO^-(aq) + H⁺(aq)

Ba(OH)2 : partially ionized (because it is a weak base)

Ba(OH)2(aq) $\rightleftharpoons$ Ba ²⁺(aq) + 2OH^-(aq)

5) Completely ionic equation :

2H⁺(aq) + SO ₄^2-(aq) + 2Na⁺(aq) + 2OH^-(aq) $\rightarrow$ 2Na⁺(aq) + SO ₄^2-(aq) + 2H₂O(l)

Net ionic equation :

2H⁺(aq) + 2OH^-(aq) $\rightarrow$ 2H₂O(l)

6) Complete ionic equation :

K⁺(aq) + NO_{​​​​​3}​​​​^-(aq) + Na⁺(aq) + Cl^-(aq) $\rightarrow$ Na⁺(aq) + NO ₃^-(aq) + K⁺(aq) + Cl^{​​​​-}(aq)

Net ionic equation : No net ionic equation.
