Question

For the reaction HBr + NaOH → Water + Salt, identify the formulas:

The acid anion formula is:
a) HBr
b) OH⁻
c) Br⁻
d) H⁺

Answer 1

The acid anion for the reaction HBr + NaOH → Water + Salt is Br⁻, which comes from the dissociation of hydrobromic acid (HBr) in water.

Step-by-step explanation:

For the reaction HBr + NaOH → Water + Salt, the formula for the acid anion is Br⁻. When hydrobromic acid (HBr) reacts with sodium hydroxide (NaOH), it forms water (H₂O) and sodium bromide (NaBr), which is the salt. The HBr dissociates into H⁺ (the acid cation) and Br⁻ (the acid anion), while NaOH dissociates into Na⁺ (the base cation) and OH⁻ (the base anion).

The correct answer to the question is c) Br⁻, which is the anion that comes from the acid HBr after it has dissociated in water.
