Is H2CO3 a base acid or salt?
Carbonic acid is a weak acid.
Carbonic acid gives an acid salt but hydrochloric acid does not Explain?
Carbonic acid gives an acid salt but hydrochloric acid does not
Which acid and base is used to make salt potassium carbonate?
Neither, it is a salt. Dissolved in water it has a pH of 7 (neutral).
Is carbonic acid base or acid?
As the name implies, it is an acid.
Is calcium carbonate carbonic acid?
No, calcium carbonate (CaCO3) is the calcium salt of carbonic acid (H2CO3). If a compound has the name of a metal in it (sodium, calcium, copper, etc) it is generally not an acid but a salt. A salt is formed when a metal ion or other positive ion takes the place of hydrogen in an acid.
Why carbonic acid gives acid salt but hydrochloric acid does not?
Hydrochloric acid (HCl) is a strong acid, and when reacted with a strong base will give a neutral salt. When reacted with a weak base it will give an acid salt. Example, HCl + NH3 => NH4Cl.Carbonic acid (H2CO3) is a weak acid and is actually CO2 + H2O. When reacted with a strong base, it will give an alkaline salt and when reacted with a weak base will give a solution the pH of which will depend on the Kb and Ka of the reactants.
Is K2CO3 acidic basic or neutral?
Considering that CO3, or carbonic ACID, this substance would be considered an acid. * actually, whoever wrote this is wrong. CO3-2 is the conjugate base of a weak acid (HCO3-, bicarbonate) K2CO3 is actually a base. and CO3, isn't called carbonic acid, it is called carbonate.
What gas is produced by adding carbonic acid to salt?
Hydrochloric acid.
Why the carbonate ion is a strong base?
It is the conjugate base of a weak acid (carbonic acid).
The conjugate acid of HCO3- is?
You mean,HCO3 - = bicarbonateH2CO3 = carbonic acid and the conjugate of the above base.
Combining a base and an acid form?
Combing an acid and a base produces a salt and water. Here are the general acid equations. Acid + Base = Salt + Water Acid + Alkali = Salt + Water Acid + Metal = Salt + Hydrogen Acid + Carbonate = Salt + Water + Carbon Dioxide. NB An Alkali is a soluble Base.
Is carbonic acid by itself a good buffer?
No. A buffer needs to have a weak acid and its conjugate base or a weak base and its conjugate acid. Additionally carbonic acid is unstable as it spontaneously decomposes into water and carbon dioxide.
