Is calcium carbonate a salt base or acid?
Calcium carbonate is an alkali salt. Alkali salts are bases, and are formed from the neutralization reaction between a strong base and a weak acid. For example: Ca(OH)2 + H2CO3 --> CaCO3 + H2O strong base + weak acid ---> alkali salt + water
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.
The conjugate acid of HCO3- is?
You mean,HCO3 - = bicarbonateH2CO3 = carbonic acid and the conjugate of the above base.
Why is H2CO3 a base?
The question is wrong. H2CO3 is formed when we introduce CO2 in water. H2CO3 can't exist in non-aqueous solutions, can't be a solid nor a gas. So we can't dissolve it in water. And H2CO3 is definitely an acid. A weak one, but still an acid.By the Bronsted-Lowry definition of acids and bases, a conjugate base is a product when an acid dissociates. For carbonic acid, this means that CO3- ions have a probability of acting as a base by taking H+ from hydronium ions in solution.H3O+ + CO32- HCO3- + H2OThis is how an antacid works, for example.This effect is most important for buffer solutions, when a weak acid is mixed with a soluble salt that has the same anion.
C02 plus H20 is a base?
No, it forms an acid, H2O + CO2 --> H2CO3 (carbonic acid)
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).

No, it forms an acid, H2O + CO2 --> H2CO3 (carbonic acid)
Is CO2 a base acid or salt?
When CO2 is dissolved with water creates H2CO3 which is a acid
What is formed when an acid and a base is mixed?
when an acid and a base combine, salt and water are formed. This process of reaction of an acid and base is called neutralisation.
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.
Is CO2 a base?
It's not a base,it's an acid. CO2 in the air is actually neither a base or an acid. However, when it comes into contact with water it reacts to become H2CO3, which is an acid.
What kind of reaction is acid plus base equals salt plus water?
2H+ + CO3^2- ==> H2CO3 ==> CO2 + H2O This is acid + carbonateFor a specific reaction, such as 2HCl + Na2CO3 ==> 2NaCl + H2CO3 ==> CO2 + H2OSO, answer to the question is salt plus CO2 and H2O
Is MgBr2 an acid or a base or a salt?
MgCO3 is called magnesium carbonate. It's classified as salt.Since that the reaction of metal with acid forms salt of acid and hydrogen gas:metal + acid --> salt of acid + hydrogen gasmagnesium + carbonic acid --> magnesium carbonate + hydrogenMg + H2CO3--> MgCO3+ H2
