Question 12. What is the pH of a 0.0023 M hydrochloric acid solution? 7.93 11.36 6.07 2.64 7.00 Classify sulfurous acid, H_2 SO_3 shown here in a neutralization reaction with ivy dioxide. H_2 SO_3(a q) + 2 OH^-(a q) SO^2_3 (a q) + 2 H_2O(I) H_2SO_3 is an Arrhenius acid, but not a Bronsted -Lowry acid. H_2SO_3 is a Lewis base. H_2SO_3 is neither an Arrhenius acid nor a Bronsted-Lowry acid.H_2SO_3 is an Arrhenius base and a Bronsted-Lowry base. H_2SO_3 is both an Arrhenius acid and a Bronsted-Lowry acid.

Explanation / Answer

12)

Ahrrenius base = will donate OH- ions

Ahrrenius acid = will donate H+ ions

Bronsted base = will accept protons, i.e. H+

Bronsted acid = will donate H+ ions, i.e. H+

Lewis base = electron pair acceptor

Lewis acid = electron pair donor

now...

in this case, SO3 is definitivly donating H+ ions so

it is an Ahrrenius ACID and a Bronsted acid

answer is e
