Acids and Bases

Question

The following acid-base reactions take place. Write the balanced molecular and net-ionic equations for each.

a.) Cyanic Acid and Sodium Hydroxide

b.) Hydrochloric Acid and Sodium Hydroxide

c.) Nitrous Acid and Rubidium Hydroxide

d.) Acetic Acid and Potassium Hydroxide

Answer 1

Anytime you have an acid + base reaction, you will end up with a salt + water and the net ionic will be some multiple of H⁺_(aq) + OH^-(aq) ==> H₂O(l)

(a) HCN(aq) + NaOH(aq) ==> NaCN(aq) + H₂O(l) ... molecular equation

H⁺(aq) + OH^-(aq) ==> H2O(l) ... net ionic equation

(b) HCl(aq) + NaOH(aq) ==> NaCl(aq) + H₂O(l) ... molecular equation

H⁺(aq) + OH^-(aq) ==> H2O(l) ... net ionic equation

(c) HNO2(aq) + RbOH(aq) ==> RbNO2(aq) + H2O(l) ... molecular equation

H⁺(aq) + OH^-(aq) ===> H₂O(l) ... net ionice equation

(d) CH3COOH(aq) + KOH(aq) ==> CH3COOK(aq) + H2O(l) ... molecular equation

CH3COOH(aq) + OH^-(aq) ==> CH3COO^-(aq) + H₂O(l) ... net ionic equation
