what are the solute particles present in boric acid (H3BO3)?
I assume you mean in a water solution.
I will write it as B(OH)3.
B(OH)3 + HOH ==> H^+ + B(OH)4^-
H3BO3 is not a Bronsted-Lowry acid but it acts as a Lewis acid.
the question was to check all that apply:
It doesn't make sense to me to talk about solute particles when there is no solvent. In water solution the particles would be H^+, H3BO3, and B(OH)4^- but that last one is not listed.
