Did you know?
WebConsequently, phosphorus acid (H3PO3 )is dibasic as it contains two P-OH bonds whereas phosphoric acid (H3PO4) is tribasic as it contains three P-OH bonds. Oxoacids of phosphorus having P-H bonds have strong reducing properties.On these grounds, we may conclude that hypophosphorus acid containing two P-H bonds and thus acts as a good … WebFor H3PO3, which is actually a diprotic acid, Ka1 = 1.50 x 10-2 and Ka2 = 1.87 x 107.
