... 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 hydrogen chloride known as?
Hydrogen chloride in aqueous solution is commonly known as hydrochloric 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?
To separate hydrated copper sulfate from its aqueous solution, you can use the process of evaporation. Heat the solution to evaporate the water, leaving behind solid copper sulfate crystals. These crystals can then be collected through filtration or decantation.
What is acidity of hydrogen chloride?
Hydrogen chloride is an acid and its acidity depends on the concentration of the solution. For example, a 0.1M solution of HCl has a pH value of 2.0
How do you make a 0.001N HCL solution?
Add 50 mL of HCl 1 N in a 1 L volumetric flask, class A or B; add ca. 900 mL distilled water to the flask. Place the flask in a thermostat at 20 0C. After 30 min add slowly distilled water to the mark (1 L) and stir well the closed flask. Pour the solution in a bottle. Place a label with the date, concentration, name of the solution on the bottle.
Calculate the mole fraction of HCl in 20 percent aqueous solution?
The mole fraction of HCl in a 20% aqueous solution can be calculated by converting the percentage to a molarity concentration. Assuming the density of the solution is 1 g/mL, a 20% solution means 20g of HCl in 100g of solution. If the molar mass of HCl is 36.5 g/mol, we can calculate the molarity and then use it to find the mole fraction of HCl in the solution.
What is hydrochloric acid in aqueous solution?
This is a solution of hydrogen chloride (HCl) in water.
What is the pH of 0.0001M aqueous solution of hcl?
The pH of a 0.0001M aqueous solution of HCl is 4. The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution. Since HCl is a strong acid that dissociates completely in water, the concentration of H+ ions in a 0.0001M solution of HCl is also 0.0001M.
Is HCL acidic in aqueous solution?
Yes, hydrochloric acid (HCl) is acidic in aqueous solution. It dissociates into H+ and Cl- ions in water, resulting in the release of hydrogen ions that make the solution acidic. It has a pH lower than 7.
Why is HCL gas not an acid but HCL aqueous an acid?
HCl gas is not an acid because it does not produce H+ ions in solution when dissolved in water. However, when HCl gas dissolves in water to form hydrochloric acid (HCl aqueous), it dissociates into H+ and Cl- ions, making it acidic.
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?

What is Aqueous HCi?
Aqueous HCl refers to hydrochloric acid that has been dissolved in water, resulting in a solution of HCl molecules and water molecules. In this form, HCl can conduct electricity due to the dissociation of the acid into H+ ions and Cl- ions.
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.
The pH of a 0.1 molar aqueous solution of HCl would equal -?
The pH of a 0.1 molar aqueous solution of HCl would be 1. This is because HCl is a strong acid that completely dissociates in water to produce H+ ions, resulting in a high concentration of H+ ions in solution, leading to a low pH value.
What is aqueous HCl?
An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations by appending (aq) to the relevant formula. The word aqueous means pertaining to, related to, similar to, or dissolved in water. As water is an excellent solvent as well as naturally abundant, it logically has become a ubiquitous solvent in chemistry.An aqueous solution is a solution in which the solvent is water.

What is the pH of an aqueous solution of HCl with a concentration of 42m?
The pH of a 42m HCl solution would be approximately -log(42) = -1.62. This solution is strongly acidic.
