Powdered aluminum serves the reducing agent for this reaction. Aluminum powder is known as a powerful reducing agent. <span>Iron(iii) ions would have greater electron affinity as compared to a metallic aluminum thus it would easily gain electrons from aluminum making it less positive in this case formed into a neutral atom. </span><span>The chemical reaction is </span>
<span>Fe2O3 + 2Al = Al2O3 + 2Fe.
</span>
<span>Oxygen in the oxide compound does not participate in this redox reaction, as it is not changed </span>chemically<span>. Fe2O3 is an ionic compound which has of Fe[3+] ions and O[2-] ions. So, the net ionic reaction would be</span>
<span>Fe3+ + Al + 3O2- = Al3+ + Fe + 3O2- </span>
<span>The ionization energy of aluminum is greater than that of iron, so the said reaction would generate large amount of heat which is needed in welding.</span>

A Brønsted-Lowry acid is defined as a compound that gives hydronium ions to another compound—for example, hydrochloric acid gives H+ ions to compounds it reacts with. Brønsted-Lowry bases are compounds that can accept hydronium ions—when ammonia gets a hydronium ion from HCl, it forms the ammonium ion.
Answer:
According to the Brønsted definition, an acid is a substance capable of donating a proton, and a base is a substance capable of accepting a proton. ... The species giving up the proton is HCl, an acid. The species accepting the proton is water, the base. The species Cl- is the conjugate base of HCl.
