The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
Balanced Chemical Equation:<\/strong><\/h3>\n\n\n\n
The given reaction involves calcium sulfite (CaSO3\\text{CaSO}_3CaSO3\u200b) reacting with hydrochloric acid (HCl\\text{HCl}HCl). Calcium sulfite is a salt of a weak acid (sulfurous acid, H2SO3\\text{H}_2\\text{SO}_3H2\u200bSO3\u200b) and a strong base (calcium hydroxide). When this salt comes into contact with a strong acid like hydrochloric acid, a reaction does occur. This is an example of an acid-sulfite reaction, which typically produces a salt, water, and sulfur dioxide gas.<\/p>\n\n\n\n
The hydrogen ions from the hydrochloric acid react with the sulfite ion (SO32\u2212\\text{SO}_3^{2-}SO32\u2212\u200b) in calcium sulfite to form sulfurous acid (H2SO3\\text{H}_2\\text{SO}_3H2\u200bSO3\u200b). However, sulfurous acid is unstable and readily decomposes into sulfur dioxide (SO2\\text{SO}_2SO2\u200b) and water (H2O\\text{H}_2\\text{O}H2\u200bO):H2SO3\u2192SO2(g)+H2O(l)\\text{H}_2\\text{SO}_3 \\rightarrow \\text{SO}_2(g) + \\text{H}_2\\text{O}(l)H2\u200bSO3\u200b\u2192SO2\u200b(g)+H2\u200bO(l)<\/p>\n\n\n\n
Simultaneously, the calcium ion (Ca2+\\text{Ca}^{2+}Ca2+) combines with the chloride ions from hydrochloric acid to form calcium chloride (CaCl2\\text{CaCl}_2CaCl2\u200b), which is soluble in water and remains in the aqueous phase.<\/p>\n\n\n\n
To balance the overall equation, two moles of hydrochloric acid are needed for each mole of calcium sulfite. One mole of HCl\\text{HCl}HCl neutralizes one hydroxide equivalent (due to the 2+2+2+ charge on calcium), and the other proton contributes to forming H2SO3\\text{H}_2\\text{SO}_3H2\u200bSO3\u200b.<\/p>\n\n\n\n
The visible signs of this reaction include the evolution of sulfur dioxide gas (which has a sharp, choking odor) and the dissolution of the solid calcium sulfite. This reaction demonstrates both acid-base behavior and gas evolution, making it a type of double displacement followed by decomposition.<\/p>\n\n\n\n
Because gas is released and products are formed, this is not a case of \u201cno reaction.\u201d The reaction is chemically feasible and proceeds as written.<\/p>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
