What makes the Arrhenius acid and an Arrhenius base definition incomplete or lacking

Answer:

See Explanation

Explanation:

The Arrhenius acid-base theory defines an acid as a compound which when added into water increases the hydronium ion (H₃O⁺) concentration and the base as a compound which when added into water increases the hydroxide (OH⁻) ion concentration. As such, an acid-base reaction is limited to proton transfer to only OH⁻ ions forming water. Such would imply that all acid-base reactions produce water only in addition to a salt. This is not always the case as conjugate base anions for many substances can receive proton transfer.

Example: The reaction HOAc + NaCN => HCN + OAc- will occur in aqueous media because the proton (H⁺) on acetic acid (HOAc) will transfer to the cyanate ion forming hydrocyanic acid (HCN). Such occurs because the CN⁻ ion is a stronger conjugate base than the acetate ion (OAc⁻) and forms the more stable weak acid. Such is the basis of the Bronsted-Lowry Acid-Base system and states that an acid (proton donor) will transfer its ionizable hydrogen to a conjugate base (proton acceptor) if the transfer forms a weaker acid.

Balance the following skeleton reactions and identify the oxidizing and reducing agents:(b) CrO₄²⁻(aq) + Cu(s) → CrOH₃(s) + CuOH

andrew-mc [135]

The balanced skeleton reactions are given below

2CrO₄²⁻(aq) + 3Cu(s) +8 $H_{2} O$ (l) → 2Cr(OH)₃(s) + 3Cu(OH)₂(s) + 6 $OH^{-}$ (aq)

The oxidising agent and reducing agents are Cr and Cu .

There are following steps involve in balance redox reaction in basic medium .

First divide the reaction into two half reactions which give oxidation and reduction half reaction.

Then balance the elements other than oxygen and hydrogen atom.

Balance the oxygen atom by adding $H_{2} O$ where number of oxygen is less .

Balance the hydrogen atom by adding $H^{+}$ on another side of where water molecule added.
Add $OH^{-}$ ions to both sides to neutralize $H^{+}$ ion.
Combine $H^{+}$ and $OH^{-}$ ion to make $H_{2} O$ .

Balance the charge by adding $e^{-}$ .

Add the half reaction .

The species which reduces the other species in the redox reaction is called oxidizing agent . Similarly , the species which oxidize the other species in the redox reaction is called reducing agent .
