When KOH dissolves in water, it separates into K+ and OH-. Under the Arrhenius definition, how is KOH classified?
HCl(aq) reacts with water to form H3O+ and Cl-. Under the Arrhenius definition, how is HCl classified?
Ba(OH)2 dissolves in water as Ba2+ and 2OH-. What Arrhenius label fits Ba(OH)2?
HNO3 in water forms H3O+ and NO3-. Which Arrhenius classification applies?
NaCl dissolves in water as Na+ and Cl- and does not produce H3O+ or OH-. Under Arrhenius acid-base definitions, what is NaCl?
For NH3 + H2O ⇌ NH4+ + OH-, which reactant acts as the Brønsted-Lowry acid?
In HCl + H2O → H3O+ + Cl-, which reactant is the Brønsted-Lowry base?
In HSO4- + H2O ⇌ SO42- + H3O+, which species acts as the Brønsted-Lowry acid in the forward reaction?
For CO32- + H2O ⇌ HCO3- + OH-, which species accepts H+ in the forward reaction?
In HF + H2O ⇌ F- + H3O+, which reactant donates H+ in the forward reaction?
For H2PO4- + NH3 ⇌ HPO42- + NH4+, which reactant is the Brønsted-Lowry base?
For HCl + H2O → H3O+ + Cl-, which listed pair is a conjugate acid-base pair?
In NH3 + H2O ⇌ NH4+ + OH-, which pair differs by exactly one H+?
For HCO3- + H2O ⇌ CO32- + H3O+, which listed pair is conjugate acid-base?

For HCN + H2O ⇌ CN- + H3O+, which listed pair is a conjugate acid-base pair?
In NH3 + H2O ⇌ NH4+ + OH-, why can NH3 be a Brønsted-Lowry base even though it has no OH group?
Which requirement belongs to the Arrhenius definition but not to the Brønsted-Lowry definition?
HCl(g) transfers H+ to NH3(g) with no water present. Which definition can still classify HCl as an acid in that reaction?
