For each of the following aqueous reactions, identify the acid, the base, the conjugate base, and the conjugate acid. (Type your answer using the format [NH4] for NH4 and [Ni(CN)4]2- for Ni(CN)42-.) (a) Al(H2O)63 H2O equilibrium reaction arrow H3O Al(H2O)5(OH)2

Acid: [Al(H₂O)₆]³⁺

Base: H₂O

Conjugate base: [Al(H₂O)₅(OH)]²⁻

Explanation:

(a) For the reaction:

[Al(H₂O)₆]³⁺  + H₂O  ⇄  H₃O⁺ + [Al(H₂O)₅(OH)]²⁻

The acid: [Al(H₂O)₆]³⁺

The base: H₂O

The conjugate base: [Al(H₂O)₅(OH)]²⁻    

According to the Bronsted-Lowry acid-base theory, the reaction of an acid and base occurs by the exchange of a proton. The acid forms its conjugate base, and the base forms its conjugate acid in the reaction.

Hence, by the above definition, the [Al(H₂O)₆]³⁺ is the acid that forms its conjugate base [Al(H₂O)₅(OH)]²⁻ and the H₂O is the base that forms its acid conjugate H₃O⁺ when they react and the  [Al(H₂O)₆]³⁺ lose a proton to the H₂O.  

I hope it helps you!

It's all about understanding the concept, see my explanation.

Explanation:

A ionic bond is formed between a metal element and a non metal element always. On the other hand, a molecular bond or covalent bond is formed between 2 elements which are both non metals. A ionic bond is made when there is a electron transfer occurring meaning that one element is giving it's electron to another to ethier become a postive or negative ion. Whereas a molecular bond is made when two non metals elements share there electrons.

• An example of a ionic bond would be MgCl2 as we know magnesium is a metal and chlorine is a non metal.

• An example of a molecular bond would be NF

which we know are both non metals.
