Best Answer

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)

What is the difference between monobasic and dibasic acids?

A monobasic acid releases on H+ when dissolved in water. Whereas a dibasic acid will release 2.

What is biprotic acid?

Diprotic or dibasic acids are those which may produce two protons (H+ ions) per molecule in aqueous solutions as H2SO4.

Is malonic acid a diprotic acid?

Yes, it is diprotic, HOOC-CH2-COOH

Why sulphuric acd is dibasic acid?

sulphuric acd is dibasic acid.It is because it can give two hydrogens which makes it dibasic acid.

What is difference between H2SO3 and H2SO4?

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.

Is permanganic acid a diprotic acid?

No, permanganic acid (HMnO4) is monoprotic.

Why is phosphorus acid dibasic?

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.

Is sulphuric acid monobasic?

No. It is dibasic.

What is the basicity of oxalic acid?

Is oxalic acid dibasic?

Yes, oxalic acid is a compound just like all other acids.

Is ascorbic acid monoprotic or diprotic?

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.

Is succinic acid polar?

Succinic acid is a weak diprotic acid (CH2COOH).
