Question

write the net ionic equation for the following molecular equation.
hbr is a strong electrolyte. hf is a weak electrolyte.
kf(aq)+hbr(aq)→kbr(aq)+hf(aq)
(use the lowest possible coefficients. be sure to specify states such as (aq) or (s). if a box is not needed, leave it blank.)

Explanation:

Step1: Write the complete ionic equation

Since \(HBr\) is a strong electrolyte (\(HBr(aq)\to H^{+}(aq)+Br^{-}(aq)\)), \(KF\) is a strong electrolyte (\(KF(aq)\to K^{+}(aq)+F^{-}(aq)\)), and \(KBr\) is a strong electrolyte (\(KBr(aq)\to K^{+}(aq)+Br^{-}(aq)\)), while \(HF\) is a weak electrolyte (remains as \(HF(aq)\)).
The complete ionic equation is:
\(K^{+}(aq)+F^{-}(aq)+H^{+}(aq)+Br^{-}(aq)\to K^{+}(aq)+Br^{-}(aq)+HF(aq)\)

Step2: Cancel the spectator ions

The spectator ions (\(K^{+}\) and \(Br^{-}\)) cancel out.

Answer:

\(F^{-}(aq)+H^{+}(aq)\to HF(aq)\)
