Question

Select an acid and a base for a neutralization reaction that results in the formation of

(a) potassium bromide;
(b) zinc nitrite;
(c) calcium cyanide,
(d) potassium phosphate.

write the balanced equation for each reaction

Answer 1

Selecting acids and bases for neutralization reactions involves pairing substances that, when reacted, form the desired salt and water. The resulting balanced equations for potassium bromide, zinc nitrite, calcium cyanide, and potassium phosphate demonstrate the stoichiometry of such reactions.

Step-by-step explanation:

Selecting Acids and Bases for Neutralization Reactions

To select appropriate acids and bases to react together and form specific salts through neutralization reactions, we must consider the ionic components that make up the desired salt product. Below are the acid-base pairs and balanced equations for the formation of various salts:

1. Potassium Bromide (KBr): The reaction between hydrobromic acid (HBr) and potassium hydroxide (KOH) yields potassium bromide and water.
   
2. Zinc Nitrite (Zn(NO2)2): The reaction between nitrous acid (HNO2) and zinc hydroxide (Zn(OH)2) yields zinc nitrite and water.
   
3. Calcium Cyanide (Ca(CN)2): The reaction between hydrocyanic acid (HCN) and calcium hydroxide (Ca(OH)2) yields calcium cyanide and water.
   
4. Potassium Phosphate (K3PO4): The reaction between phosphoric acid (H3PO4) and potassium hydroxide (KOH) yields potassium phosphate and water.
