Complete these Bronsted-Lowry reactions.
reaction 1: H2PO4– + H+ ⇌
reaction 2: H2PO4– + OH– ⇌
♦ Relevant knowledge
Bronsted-Lowry theory suggests that acids are proton donor whereas bases are proton acceptor. It’s a more comprehensive classification of bases and acids as compared to Arrhenius theory due to the fact that bases are Bronsted bases that don’t make hydroxide when dissolving in water. This is similar to ammonia.
SOLUTION:
REACTION 1:
In this case, H2PO4– is Bronsted-Lowry base and it accept proton (H+).
REACTION 2:
H2PO4– acts Bronsted-Lowry acid and it gives proton (H+).
