A seguir são apresentadas algumas afirmações. Classifique-as como verdadeiras ou falsas. No caso de afirmações falsas, reescreva-as, corrigindo o que for necessário.

a) o ácido conjugado de HPO42 - é PO43-

b) a teoria de Bronsted-Lowry pode ser aplicada a qualquer solvente.

c) o ácido conjugado de NH3 é NH4+

d) a teoria de Arrhenius diz que ácido é qualquer substância que perde H+.

Below are some statements. Classify them as true or false. In the case of false statements, rewrite them, correcting what is necessary.

a) HPO42 - conjugated acid is PO43-

b) the Bronsted-Lowry theory can be applied to any solvent.

c) the NH3 conjugate acid is NH4 +

d) Arrhenius' theory says that acid is any substance that loses H +.

Answer:

A) false

B) false

C) true

D) true

Explanation:

The conjugate acid refers to the acid which donate proton so the conjugated acid of HPO42 - is not PO43. it is H2PO4. The Bronsted-Lowry theory can be applied to most of the solvent not all solvents. The conjugate acid of NH3 is NH4 +

. Arrhenius' theory says that acid is any substance that loses H + during a chemical reaction while the base is those substance which donates OH - ion.
