H+ and SO4 (2-) above the 4
In an aqueous solution of H2SO4 (sulfuric acid), the predominant ionic species present are H+ (hydrogen ions) and HSO4- (bisulfate ions). These ions are formed as sulfuric acid dissociates in water.
If water is present in the volumetric flask when transferring the H2SO4 solution from the pipette, the final concentration of H2SO4 will be diluted. This is because the water will mix with the H2SO4 solution, increasing the total volume in the flask without adding more H2SO4 molecules. As a result, the concentration of H2SO4 will be lower than intended.
To standardize 1N H2SO4 with KHP, you would first prepare a solution of KHP of known concentration. Then, titrate the KHP solution with the 1N H2SO4 solution until the endpoint is reached. The volume of H2SO4 used in the titration can then be used to calculate the exact concentration of the H2SO4 solution.

The concentration of hydrogen ions in a 0.1M solution of H2SO4 is 0.2M.

When sulfuric acid (H2SO4) dissolves in water, it ionizes into hydronium ions (H3O+) and sulfate ions (SO4^2-). The equation for this dissociation is: H2SO4 + H2O → H3O+ + HSO4-.
To prepare 1N H2SO4 from 95% H2SO4, you would first need to dilute the 95% H2SO4 with water by adding the appropriate amount of water to achieve the desired concentration. To calculate the volume of 95% H2SO4 needed to make 1N solution, you need to use the formula: (Normality of stock solution) * (Volume of stock solution) = (Normality of diluted solution) * (Volume of diluted solution). Adjust the volumes accordingly to prepare the desired 1N solution.
To prepare a 0.005 M solution of H2SO4 with pH 4, you can first calculate the concentration of H+ ions needed to achieve a pH of 4. Then, use the dissociation of H2SO4 to determine the amount of H2SO4 needed to provide that concentration of H+ ions. Finally, dilute the calculated amount of H2SO4 with water to reach the desired volume of the solution.
The aqueous solution of H2SO4 is called sulfuric acid.
First, calculate the mass of the H2SO4 in 16.4 mL of the solution using its density. Then, determine the mass of H2SO4 in the 16.4 mL solution by multiplying the mass of solution by the percentage of H2SO4. Next, convert the mass of H2SO4 to moles using its molar mass to find the number of moles.
Yes, a solution of SO2 can be acidic because it reacts with water to form sulfuric acid (H2SO4). SO2 dissolves in water to produce sulfurous acid (H2SO3), which can further react to form sulfuric acid, increasing the acidity of the solution.
The first solution is more concentrated because it contains 6 moles of H2SO4 per one liter of solution. The second solution is less concentrated because it contains 0.1 moles of H2SO4 in one liter. In equal amounts of each example, the first would have more H2SO4.
