Question

question 2 of 32 what are the products of the neutralization reaction between hcl and ca(oh)₂?
a. cl₂, cao, and h₂
b. cacl and h₃o⁺
c. cacl₂ and h₂o
d. cah and hclo

Explanation:

A neutralization reaction occurs between an acid (HCl, hydrochloric acid) and a base (Ca(OH)₂, calcium hydroxide). The general formula for a neutralization reaction is: Acid + Base → Salt + Water.

For HCl (acid) and Ca(OH)₂ (base):

• The cation from the base is Ca²⁺, and the anion from the acid is Cl⁻. Combining these, the salt formed is CaCl₂ (calcium chloride) to balance the charges (Ca²⁺ needs two Cl⁻ ions).
• The other product is water (H₂O), formed from the H⁺ ions from the acid and the OH⁻ ions from the base (H⁺ + OH⁻ → H₂O).

Now let's analyze the options:

• Option A: Cl₂, CaO, and H₂ are not products of a neutralization reaction between an acid and a base. This would be more like a redox or decomposition reaction, not neutralization.
• Option B: CaCl is incorrect (needs to be CaCl₂ to balance charges) and H₃O⁺ is not a product of this neutralization (the product is H₂O, not hydronium ions in this context).
• Option C: CaCl₂ (salt) and H₂O (water) match the products of a neutralization reaction between HCl and Ca(OH)₂.
• Option D: CaH and HClO are not products of this reaction. These compounds are not formed from the combination of HCl and Ca(OH)₂.

Answer:

C. CaCl₂ and H₂O
