... carbonic acid
Indeed, H2CO3 is called "carbonic acid." And you would think that since it is a weak acid, that there should be non-ionized molecules of H2CO3 in solution just as there are molecules of CH3COOH in a solution of ethanoic (acetic) acid. But that simply isnt the case. It has also been said that H2CO3 is an "unstable" molecule and quickly decomposes. Recent work has shown that in the absence of water, H2CO3 moleculs are quite stable. It is the pesky water moleucle that is the issue. H2CO3 molecules don't exist in aqueus solution. What we call "carbonic acid" is actually a solution of CO2 in water in equilibrium with H+ and HCO3-.
CO2(aq) + H2O(l) <==> H+ + HCO3- ..... Ka is small
Since the Ka for this equilibirum is small, the equilibrium lies far to the left, with CO2. Therefore, we see CO2 as the predominant species in a solution of "carbonic acid."

What is the state symbol for sodium hydroxide?
According to the MSDS HCl is a Liquid. It is also found dissolved in water.
How do you separate hydrated copper sulphate from its aqueous solution?
Cupric oxide (black, CuO) is not soluble, so it is easily fitered off from the cupric sulfate solution (blue, CuSO4).
The pH in aqueous solution of hcl at 25c is 4 hcl0.003 moles was added to 1l of this solution calculate the new pH in the solution assume complete dissociation of hcl?
if its complete dissociation, then the products would be a salt and water, which means the pH is 7 or neutral. OMG, if the pH is currently 4 then [H+] = 1.0 e-4 M (pH = -log[H+]) if you add 0.003 moles then 1.0e-4 M +.003 M = .0031 M (Since the strong acid HCL completely dissociates in aq solution) pH = -log [.0031M] = 2.51
Why add water to hcl solution?
To dilute it.
What was given off when ammonium chloride was heated?
since ammonium chloride is a subline solid, it gets converted into gaseous state directly without changing into liquid state
Is HCL acidic in aqueous solution?
If it is only HCL, yes.
Calculate the mole fraction of HCl in 20 percent aqueous solution?
The mole fraction of HCl in 20 percent aqueous solution is 0.21.
What is hydrochloric acid in aqueous solution?
This is a solution of hydrogen chloride (HCl) in water.
What has a pH of 1 and completely ionizes in aqueous solution?
HCl
What is the mole fraction of HCl in an aqueous solution that is 27.2 percent HCl by weight?
The mole fraction of HCl is 0.34.
What is hydrochloric acid and acid in a aqueous solution?
HCl is ionozed in aq solution HCl + H2O = H3O(+ CHARGE) + Cl (- CHARGE) HCl FORMULA WILL REAMAIN HCl OT WILL BOT CHANGE
The pH of a 0.1 molar aqueous solution of HCl would equal -?
1
Aqueous solution of gaseous HCl is acidic but solution of HCl gas in benzene has no acidic property?
This is because of the polarity of the solvents. Aqueous solution (H2O) is very polar and will produce H+ ions when HCL is added, thus resulting in a acidic solution. On the other hand, benzene, a nonpolar solvent will not produce H+ ions and no acidic properties.
How many liters of water must be added to 1 liter of an aqueous solution of hcl with a pH of 1 to create an aqueous solution with pH of 2?
9
What is the systematic name for aqueous HCl?
Hydrochloric acid
What is the molarity of H plus in an aqueous solution that is 0.17 M HCl?
0.17 Molar
What is the solute and solvent of muriatic acid?
The aqueous solution of HCl is the Muriatic acid so HCl gas is solute and water is solvent.
