They both mean the same thing:
acid molecules with 2 protons: e.g. H2O and H2S and ....
H2S --> H+ + HS-
HS- --> H+ + S2-
The two sulfides (HS- and S2-) are both base, so H2S is dibasic (= forming two bases)
Two protons are freed, so H2S is diprotic (= forming two protons)
Yes, carbonic acid is dibasic acid because it gives two H+ions on IONIZATION hence it also gives two types of salts carbonates and bicarbonates.
Monobasic acids can donate only one proton (H+) per molecule in a reaction, while dibasic acids can donate two protons per molecule. This means that dibasic acids have double the acidic strength compared to monobasic acids.
Yes, malonic acid is a diprotic acid because it has two ionizable hydrogen atoms that can donate protons in aqueous solution.
The chemical difference is the oxidation state of sulfur, but only this makes a great difference in the allover chemical properties:H2SO3, sulfurous acid, oxidation state +4, weak diprotic acid, only stable in water, without it will decompose into sulfurous oxide (gas, SO2)H2SO4, sulfuric acid, oxidation state +6, strong (second protolysis is relatively strong) diprotic acid, hygroscopical with and very stable in water.
Corrected Answer:Three main members of the phophORUS acid group are: (protons are in bold capitals)H3PO4; Phosphoric acid, PO(OH)3, tribasic acid, contains P in oxidation state +5H3PO3; Phosphorous acid,HPO(OH)2, dibasic acid, contains P in oxidation state +3H3PO2; Hypophosphorous acid, H2PO(OH), monobasic acid, contains P in oxidation state +1There is only one diprotic: H3PO3.When more structurally written as (HO)2HPOyou can see why it is diprotic: only from a P-(O-H) group the H can be ionised as H+ and can be donated as proton to a water molecule (acidic property). The H-P=O is NOT ionisable, thus not acidic.

Sulfuric acid is considered dibasic because it can donate two protons (H+) per molecule in acid-base reactions. This means it has two replaceable hydrogen atoms, allowing it to form two sets of salts.
Oxalic acid is a dicarboxylic acid and has two carboxylic acid groups. Therefore, it is a dibasic acid, meaning it can donate two protons per molecule in acid-base reactions.
Yes, oxalic acid is a dibasic acid, meaning it can donate two protons (H+) in chemical reactions. This property enables oxalic acid to form two types of salts when reacting with bases.
Oxalic acid is an organic compound, a diprotic acid, with the molecular formula H2C2O4.
No, permanganic acid (HMnO4) is monoprotic.
Diprotic, hence polyprotic.We'll documented by NIH.The two reactive hydrogen are found bonded to C2 And C3 in the molecule. You can also check the molecular formulae for ascorbic acid and dehydroascorbic acid and note the loss of TWO hydrogen.
A diprotic acid. These acids have two acidic hydrogen ions that can be donated in a chemical reaction. Examples of diprotic acids include sulfuric acid (H2SO4) and carbonic acid (H2CO3).
